4.5 Function
Design The gate valve comprises the pressure-retaining parts (body 1, bonnet 8, bonnet
extension 10 and yoke 23), the functional unit (stem 4, wedge 2 and bellows 9) and
the actuating element.
Function The valve is operated by a manual actuating element (handwheel 20) or a mechanical
actuating element (gearbox 28). Handwheel 20 is fitted on stem nut 18 by means of a
square drive or hexagon drive and secured with dust-proof nut 21.
Sealing Bonnet 8 is bolted to body 1 with studs 5 and nuts 7; the joint is sealed to
atmosphere by gasket 6. Bonnet 8 is welded with bonnet extension 10, which is
sealed with yoke 23 by means of studs 26 and nuts 25. The joint is sealed to
atmosphere by gasket 11.
The passage of stem 4 through bonnet 8 and bonnet extension 10 is sealed by
bellows 9. Back-up gland packing 13 is tightened at gland follower 16 by means of
eyebolt 15 and nuts 17. The stem seal with bellows 9 is maintenance-free. Bellows 9 is
welded to bellows end fitting 12.
The seating surfaces of seat ring 3 and wedge 2 are made of rust-proof material.

5 Installation at Site
5.1 General information/Safety regulations
Responsibility for positioning and installing the valve lies with the consultant, the
engineering contractor or the operator. Planning errors and installation errors can
prevent the reliable function of the valves and pose a substantial safety hazard.
DANGER
Dead-end valve
High-pressure hazard!
Risk of burns!
▷Protect the valve against unauthorised and/or unintentional opening.
WARNING
Exposed rotating parts
Risk of injury!
▷Do not touch rotating parts.
▷When the equipment is in operation, perform any work with utmost caution.
▷Take suitable precautions, e.g. provide safety covers.
CAUTION
Improper installation
Damage to the valve!
▷Protect the body and body bonnet/cover from any impacts.
5.2 Installation position
Always install the bellows-type gate valve vertically in a horizontal pipe. Installation
with the stem in an upward inclined, horizontal or downward inclined position (as in,
e.g. a vertical pipe) is not permitted.
Make sure that the non-rising handwheel can be operated and that there is sufficient
clearance available for the rising stem.
The position and flow direction must be in accordance with the manufacturer’s data.
The valve must not be fitted downstream of tees and level or three-dimensional
double bends.
5.3 Preparing the valve
CAUTION
Outdoor installation
Damage due to corrosion!
▷Provide weather-proof protection to protect the valve against moisture.
1. Thoroughly clean, flush and blow through all vessels, piping and connections.
2. Remove the valve's flange covers before installing it in the piping.
3. Check that the inside of the valve is free from any foreign objects. Remove any
foreign objects.
4. If required, install a strainer in the piping.

5 Installation at Site
17 of 34
ECOLINE GTB 150-600
7355.81/01-EN
5.4 Piping
CAUTION
Painting of the piping
Valve function impaired!
Loss of important information provided on the valve!
▷Protect stem and plastic components prior to applying paint.
▷Protect printed name plates prior to applying paint.
▪Lay the piping in such a way that detrimental thrust forces and bending forces
are kept away from the valve body.
▪For any further work (e.g. construction work, cleaning measures) protect the
piping against contamination (e.g. by covering it with a tarpaulin).
5.4.1 Flange connection
Fasteners Only use fasteners and sealing elements of approved materials. Always use all flange
bolt holes provided when connecting the valve to the pipe.
Flange connection üThe mating flange faces are clean and undamaged.
üVerify that the pipe is correctly aligned and the flanges are parallel.
1. Properly insert the sealing elements at the valve flanges.
2. Align the valve between the pipe flanges.
3. Use an appropriate tool to evenly tighten the fasteners crosswise.
5.5 Valve with actuator
WARNING
Impermissible loads resulting from operating conditions, add-on parts and valve-
mounted components, e.g. actuators
Leakage from or rupture of the valve body!
▷Lay the piping in such a way that detrimental thrust forces and bending forces
are kept away from the valve body.
▷Additional loads, e.g. traffic, wind or earthquakes are not taken into account
for standard variants; these require a separate design.
▷Support the valve including add-on parts and valve-mounted components.
Install valves with gearboxes or actuators with the stem axis in a vertical position. If
this requirement cannot be met, adequately support the actuator on site or consult
KSB.
Electric actuators
DANGER
Unqualified personnel performing work on valves with actuator
Danger of death from electric shock!
▷Ensure that the connection to the power supply and the process control system
is performed by a trained electrician.
▷Observe regulations IEC60364 and, for explosion-proof models, EN60079.

5 Installation at Site
18 of 34 ECOLINE GTB 150-600
7355.81/01-EN
WARNING
Incorrect connection to the mains
Damage to the power supply network, short circuit!
▷Observe the technical specifications of the local energy supply companies.
CAUTION
Change of limit switch points
Impairment of the functional reliability!
Damage to the actuator!
▷Never change the pre-set limit switch points.
Mounted actuators are factory-set and ready for operation.
Electric actuators are factory-set ready for operation and wired as follows:
▪Valve CLOSED: travel-dependent
▪Valve OPEN: travel-dependent
Circuit diagrams, see the manufacturer’s operating manual for the electric actuator.
Pneumatic actuators
DANGER
Work on valves with energy storage, e.g. spring mechanisms or compressed air
storage
Danger to life resulting from incorrect assembly
▷Ensure that work on the actuator is performed by qualified specialist personnel.
▷Observe the actuator’s operating manual.
5.6 Insulation
WARNING
Cold/hot piping and/or valve
Risk of thermal injury!
▷Insulate the valve.
▷Fit warning signs.
CAUTION
Outdoor installation
Damage due to corrosion!
▷Provide weather-proof protection to protect the valve against moisture.
For any insulation fitted on the valve observe the following:
▪The valve's function must not be impaired.
▪The sealing areas at the bonnet/cover joint and at the stem passage (gland
packing) must be directly accessible and visible.

Overloading of valve
Damage to the valve!
▷The nominal pressure classes only apply at room temperature. Refer to the
pressure/temperature ratings tables for higher temperature values. . Using the
valve in conditions deviating from those specified will lead to overload which
the valve cannot withstand.
CAUTION
Aggressive flushing liquids and pickling agents
Damage to the valve!
▷Ensure that cleaning procedure and duration match the valve body materials
and seal materials when performing flushing and pickling.
▷Responsibility for the compatibility of the pickling media used and the pickling
procedure itself lies with the pickling company.
Before commissioning/start-up of the valve ensure that the following requirements
are met:
▪The valve has been connected to the piping at both ends.
▪The shut-off function of the installed valve has been checked by opening and
closing it several times.
▪Gland packing 13 has been checked for leakage before it is subjected to load
conditions for the first time. If gland follower 16 has loosened, evenly re-tighten
nuts 17 crosswise.
▪Studs 5 and 26 as well as gaskets 6 and 11 have to be checked for any leakage
after the first rise in temperature. If any leakage has occurred, evenly re-tighten
the studs crosswise. Prior to re-tightening studs 5 and 26, slightly open the valve
to prevent jamming of the seat.
▪The actuator has been connected to the power supply in accordance with the
actuator's operating manual.
▪The piping has been flushed.
▪For valves with electric or pneumatic actuators travel limits have been set.
▪The material, pressure data and temperature data of the valve are compatible
with the operating conditions of the piping. (ðSection6.2,Page20)
▪The material's chemical resistance and stability under load have been checked.

6.1.2 Valve actuation
NOTE
Viewed from above, the valve is closed by turning the handwheel in clockwise
direction, and opened by turning the handwheel in counter-clockwise direction.
Direction symbols are marked on the top of the handwheel.
CAUTION
Excessively long idle periods
Damage to the valve!
▷Check the function by opening and closing the valve at least once or twice a
year.
CAUTION
Use of levers
Damage to the valve as a result of excessive forces!
▷Only actuate handwheel-operated valves by hand.
▷Levers may only be used in exceptional cases and in compliance with the
following tables.
▷Do not use levers in the area of the position indicator.
