Australian Pipeline Valve - Installation, Operation and Maintenance Manual2
INTRODUCTION
The majority of this information is common knowledge to experienced valve users. When properly
installed in applications for which they were designed, Flowturn valves will give long reliable service.
This instruction is only a guide for installation and operation on standard service and covers general
maintenance and minor repairs. A professional APV approved valve engineering facility should be utilised
for reconditioning or major repairs.
Note
We do recommend however that this entire document be read prior to proceeding
with any installation or repair. Australian Pipeline Valve and it’s parent company
take no responsibility for damage or injury to people, property or equipment. It is
the sole responsibility of the user to ensure only specially trained valve repair
experts perform repairs under the supervision of a qualified supervisor.
RESPONSIBILITY FOR SIGHT GLASS APPLICATION
The User is responsible for ordering the correct valves. The user is responsible for ensuring APV-Flowturn
Valves are selected and installed in conformance with the current pressure rating and design temperature
requirements. Prior to installation, the valves and nameplates should be checked for proper identification
to ensure the valve is of the proper type, material and is of a suitable pressure class and temperature
rating to satisfy the requirements of the service application.
Do not use sight glasses in applications where either the pressure or temperature is
higher than the allowable working values. Also sight glasses should not be used in
service media if not compatible with the sight glass material of construction, as this
will cause chemical attacks, leakage, valve failure.
RECEIVING INSPECTION AND HANDLING
Valves should be inspected upon receipt to ensure:
- Conformance with all purchase order requirements.
- Correct type, pressure class, size, body and trim materials and end connections.
- Any damage caused during shipping and handling to end connections, hand wheel or stem.
The User is advised that specifying an incorrect valve for the application may result
in injuries or property damage. Selecting the correct valve type, rating, material
and connections, in conformance with the required performance requirements is
important for proper application and is the sole responsibility of the user.

SAFETY INFORMATION
The following general safety information should be taken in account in addition to the specific warnings
and cautions specified in this manual. They are recommended precautions that must be understood and
applied during operation and maintenance of the equipment covered in this I.O.M.
To avoid injury, never attempt disassembly while there are pressures either
upstream or downstream. Caution is necessary to avoid possible injury.
To prevent bending, damage, inefficient operation, or early maintenance problems,
support piping on each side of the sight glass.
• A sight glass is a pressurised mechanism containing energised fluids under pressure
and consequently should be handled with appropriate care.
• Valve surface temperature may be dangerously too hot or too cold for skin contact.
• Upon disassembly, attention should be paid to the possibility of releasing
dangerous and or ignitable accumulated fluids.
• Ensure adequate ventilation is available for service.
This manual provides instructions for storing, general servicing, installation and removal of SLSG Series
Sight Glasses.
APV and it’s resellers refuse any liability for damage to people, property or plant as well as loss of
production and loss of income under any circumstances but especially if caused by: Incorrect installation
or utilisation of the valve or if the valve installed is not fit for intended purpose. It is the sole
responsibility of the user to ensure the valve type and materials are correctly specified.

SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual4
DURING OPERATION TAKE INTO ACCOUNT THE FOLLOWING WARNINGS:
a- Graphite body gaskets are very brittle, any impacting, twisting or bending should be avoided. PTFE
gaskets must not have any scrathes to surface.
b- The sight glass’s internal parts such as flow indicator, pin & gasket shall be handled with care.
c- All tools and equipment for handling the internal parts shall be soft coated.
d- Valves can be fitted with gaskets or seals in PTFE, Buna, EPDM, NBR, Viton, etc., hence chemicals or high
temperatures will damage sealing components.
For all operations make reference to position number on part list of the applicable drawing listed.
Bonnet seal could result in personal injury. Bonnet is tightened prior to shipping but
may require replacement seal or tightening to meet specific service conditions.
Personal injury may result from sudden release of any process pressure. APV
recommends the use of protective clothing, gloves and eye wear when performing
any installation or maintenance.
Isolate the sight glass from the system and relieve pressure prior to performing
maintenance.
Disconnect any operating line providing air pressure, control signals or electrical
power to actuators.
If a gasket seal is disturbed while removing or adjusting gasketed parts, APV
recommends installing a new gasket while reassembling. A proper seal is required
to ensure optimum operation.

SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual 5
1.0 INSTALLATION
Piping should be properly aligned and supported to reduce mechanical loading on
the end connections.
1.1 INSTALLATION POSITIONS
Sight valves fitted with flow indicators are uni-directional, the direction of flow will be indicated on the
valve body. Sight glasses with indicators should be used for horizontal lines with the bonnet facing up,
and vertical lines where the direction of flow as indicated on the valve body is upwards.
1.2 PREPARATION FOR INSTALLATION
• Remove protective end caps or plugs and inspect valve ends for damage to flange faces.
• Thoroughly clean adjacent piping system to remove any foreign material that could cause damage to
seating surfaces during valve operation.
• Verify that the space available for installation is adequate to allow the valve to be installed and to be
operated.
1.3 POST-INSTALLATION PROCEDURES
After installation, the line should be cleaned by flushing to remove any foreign material. When caustics
are to be used to flush the line, additional flushing with clean water is required. The valve should be
tested after installation to ensure proper operating function.
With the line pressurised, check the valve end connections, body to bonnet/cover joints and plugs for
leaks.
2.0 HANDLING
1. Take care in handling sight glasses especially the sealing faces.
2. Make sure that piping and equipment is clean of dust, rust and pipeline scale. Clean all adjoining pipe
and fittings. Remove end protector covers from the valves immediately prior to installation. Blow
compressed air inside the valves to remove residual dust, dirt, etc., from inside the sight glasses as this
could hamper the valves functioning and could also damage the seats.
3. Make bonnet joints tight but do not overstress them. Always tighten in a diagonal pattern, gradually
increasing torque settings. Refer to Appendix A, Diagram 1.
4. Install sight glasses in the connecting piping so that the arrow mark on the valve body coincides with
the flow direction in the pipe.
5. After installation it is advisable to once again flush the piping. Check carefully for visible leaks if any
and tighten bonnet nuts accordingly.

SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual6
6. If the leakage still persists change the bonnet gasket.
Proper safety equipment and apparel should be worn when preparing to service the
sight glass.
3.0 OPERATION
The sight glass operation is automatic and requires no assistance. When the flow exerts sufficient
pressure against the disc to overcome the flow indicator’s weight, the disc allows the flow to continue
through the piping system.
Flow indicators do not act as check valves.
4.0 MAINTENANCE DURING
OPERATION
The sight glass may experience leakage after a certain period of operation; maintenance should be
performed as follows:
4.1 LEAKING BETWEEN SIGHT GLASS BODY AND SIGHT GLASS CAP
After a period of operation, the tightening force between the sight glass body and sight glass cap could
become weaker, resulting in less pressure against the gasket and therefore a leak.
Adequately tighten the bolts connecting the cap to the body with a proper wrench, so as to enhance the
sealing effect of the gasket between the cap and the body by increasing the pressure and therefore
stopping the leak. Refer to Appendix A for bolting torques. For screwed bonnet deisng, utilise tightening
lugs on bonnet. If there is still a leak replace the bonnet gaskets.

SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual 7
Personal injury may result from sudden release of any process pressure. APV
recommends the use of protective clothing, gloves and eye wear when performing
any installation or maintenance.
Isolate the sight glass from the system and relieve pressure prior to performing
maintenance.
Disconnect any operating line providing air pressure, control signals or electrical
power actuators.
5.0 DISASSEMBLING SIGHT
GLASSES
1. Check that the line is in a complete shut down phase.
2. Pre-order all necessary jointing gaskets and parts.
3. Check to ensure the flow indicator is functioning correctly.
4. If the bolts and nuts are too tight, apply deep penetrating oil and then unscrew.
6.0 REPAIR
After a certain period of operation, the the product still leaks after the above mentioned maintenance,
repair should be performed as follows:
6.1 REPAIRING THE LEAK AT THE BODY-CAP JOINT & REPLACING BODY GASKET
Dis-assembly
a. Remove stud bolts joining the body and cap (or unscrew the bonnet in the case of screwed bonnet
version).
b. Remove the gasket
c. Remove the sight glass
d. Remove the gasket
Assembly
a. Place the new gasket in position; ensure that the gasket is smoothly placed.
b. Place the sight glass onto the gasket.
c. Place the new gasket onto the glass; ensure that the gasket is smoothly placed.
d. Place the cap onto the body and tighten the stud bolts.

SIGHT GLASSES - SLSG SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual8
7.0 REASSEMBLY
1. Re-assemble in reverse order of disassembly.
2. Refer Appendix A for bonnet bolt re-tightening procedure and torques.
8.0 PREVENTATIVE MAINTENANCE
Sight glasses require virtually no maintenance but ensure during normal functioning the flow indicator is
not hammering or slamming.
9.0 LEAKAGE ACROSS GASKET
Should any bonnet gasket leaks occur, tighten the bolts/nuts & studs (refer Diagram 1, Appendix A). If
leakage still persists, the bonnet gasket should be changed, refer to 10.1 below.
10.0 MAJOR MAINTENANCE
Only an expert valve re-conditioner should attempt the following major maintenance/repairs.
Sight glasses require very little maintenance. Generally, the only viable repairs are replacement of bonnet
gasket. However, see below for further extraordinary repairs.
Always replace the bonnet gasket whenever a sight glass is disassembled. Gasket seating surfaces should
be scraped clean (avoid radial marks). Bonnet bolts should be tightened in a diagonal pattern at several
different increasing torque settings in accordance with the recommended torque value (see Diagram 1,
Appendix A).
10.1 GASKET REPLACEMENT
1. Disassemble all cover bolts and nuts (or unscrew if a screwed bonnet).
2. The bonnet should be easy to remove without the aid of a mechanical lifting device. Gently break the
seal with a lever, gradually lifting the bonnet flange at intervals 360° around the bonnet.
3. Clean gasket surface areas, replace gasket and refit bonnet as detailed in 10.0 above.
10.2 SIGHT GLASS INTERNALS DISASSEMBLY INSPECTION AND REPAIR
1. Check that the (where applicable) hinge pin, nut and sight flow indicator are in good condition and
firmly connected. Replace damaged parts as necessary.
2. Lift and remove the sight flow indicator assembly. Movement should be free and not hindered by any
