4.4. POSITIONING
Position the valve in a way that facilitates inspections and reviews. Allow sufficient space around the valve
for adequate review, dismantling and maintenance (see table in section 4.8.1. Single seat relief valve,
weld/weld).
4.5. DIRECTION OF FLOW
The following image indicates the recommended direction for product flow, as well as the direction of
closing, depending on the type of valve. Following these indications will prevent water hammer and its
consequences to the extent possible, which can occur when single-seat valves close.
The recommended direction will always be contrary to the movement of valve closing; that is, when the
valve is closing, the valve will always work against the pressure of the fluid.
4.6. GENERAL INSTALLATION
After the location of the valve is defined, the pipe can be joined by welding the valve housing or using
fittings. In this case, do not forget the seals, and tighten the unions
properly.
Before starting to weld the valve housings to the pipe, disassemble the
valve to prevent damage to the joints, following the instructions in
section 7.4. Assembly and disassembly.
Avoid using excessive force when assembling the valves, and pay special
attention to:
Vibrations that may be produced on the facility.
Thermal dilation that the pipe may undergo when hot fluids are
circulating.
The weight that the pipe can support.
Excessive welding current.

10 4. Installation (0) 2018/05
4.7. CHECKING AND REVIEW
Perform the following checks before using:
Check that the clamps and nuts are well secured.
Open and close the valve (applying compressed air to the actuator) several times to make sure it
operates correctly and to make sure that the shaft joint is coupled smoothly to the valve housing.
4.8. WELDING
Welding work should only be done by qualified persons who are trained and equipped with
the necessary equipment to perform this kind of work.
Before starting welding, disassemble the valve as explained in section 7.4. Assembly and disassembly.
4.8.1. Single seat relief valve, weld/weld
Disassemble the valves as indicated in section 7.4. Assembly and disassembly.
Weld the valve housing to the pipes.

5. Start-up
Valve start-up can be done if the instructions detailed in chapter 4. Installation have been followed first.
5.1. USES OF THE VALVE
It is widely used as a bypass valve for the positive displacement pumps. It is also used to protect the
equipment in case of excessive pressure.
5.2. START-UP
Prior to start-up, the persons in charge must be duly informed about how the valve works
and the safety instructions to follow. This instruction manual will be available to personnel
at all times.
Before putting the valve/actuator into service, the following must be taken into consideration:
Check that the piping and valve are completely free of possible traces of welding slag or other
foreign particles. Clean the system if necessary.
Check to make sure the valve moves smoothly. If necessary, lubricate it with special grease or
soapy water.
Check for possible leaks, and make sure the pipes and their connections are sealed and do not
have any leaks.
If the valve has been supplied with an actuator, make sure that the alignment of the valve shaft
and the actuator shaft enables smooth movement.
Check that the compressed air pressure at the inlet to the actuator matches what is indicated in
the Technical specifications.
Consider the quality of the compressed air, according to the specifications described in chapter 8.
Technical specifications.
Actuate the valve.
5.3. OPERATION
Do not modify the operating parameters for which the valve has been designed without
prior written authorisations from INOXPA.
Do not touch the moving parts of the coupling between the actuator and the valve when the
actuator is connected to the compressed air supply.
Burn hazard! Do not touch the valve or the pipes when hot fluids are circulating or when
cleaning and/or sterilization are being carried out.

(0) 2018/05 5. Start-up 13
5.4. VALVE SETTING
Type J valve can be set by client. Calibration requires a pump, a pressure gauge (to measure the
pressure), a shut-off valve and Type J valve.
Start up the pump with the shut-off valve in the closed position. The liquid will pass through the Type J
valve, which will act as a bypass (recirculation). Tighten the top screw (previously loosening the lock nut)
on the TypeJvalveuntilthepressuregaugeindicatesthepump’smaximumworkingpressure.Thevalve
will then be set to the pressure indicated on the pressure gauge; if this pressure is exceeded, the valve
will close and the flow will be recirculated, thus preventing any damage to the system.
