8 3.Receipt and Installation 2021/12
3.6. ASSEMBLY
Install the valve in process pipework according to good trade practice.
Once the location of the valve has been established, the pipes can be connected by either welding to the body of the
valve or by means of hygienic unions. In the latter case ensure that seals are fitted and the joints fully tightened.
Before welding the bodies to the pipework, disassemble the valve to prevent damage to the
diaphragm.
Excessive stress should be avoided during the assembly of
the valves and special attention should be given to the
following:
•Vibration which may be produced in the installation.
•Expansion of the pipes during circulation of hot liquids.
•The weight that the pipes can withstand.
•Excessive intensity of welding.
For the valve to be completely drainable, it must be
placed at an angle of 2oto 3oin the line of the tube,
and 20oon a perpendicular plane to the tube, as
shown in the figure.
The designer and/or user is/are
ultimately responsible for drainage
of the process.
3.7. INSPECTING AND CHECKING
Check the following before use:
•Check that the screws are very tight. See
tightening torque in chapter 8. Technical
Specifications .
•Open and close the valve (applying
compressed air to the actuator or moving
manually if a handle is available) several
times to ensure that it operates correctly.
Check that the diaphragm closes completely.

Disassemble the valve before starting the welding work.
3.8.1. Weld/weld diaphragm valve.
•Disassemble the valve as indicated in section 7. Assembly and disassembly
•Weld the valve body to the pipework.
•When welding the valve body, it is very important to maintain the minimum distance (dimension A) enabling
disassembly of the valve for later checks and replacement of valve parts (e.g. diaphragm or actuator).
3.9. AIR CONNECTION TO ACTUATOR
•Connect and check the air connections as required. Single Acting Spring Return or Double Acting.
•INOXPA valves are supplied with Ø6 tube connections and a silencer in Single Acting actuators.
•Bear in mind the quality of the compressed air in accordance with the specifications described in chapter 8
Technical Specifications.
The compressed-air pressure for the NO and A/A actuators (normally open and double acting)
is less than in type NC (normally closed). See chapter 8. Technical Specifications.
Excess pressure may seriously damage the diaphragm and actuator.

4.Start-up
The start-up of the valve can be carried out provided the instructions indicated in Chapter 3 –Receipt and Installation
have been followed.
4.1. START-UP
Before start-up, the responsible persons should be aware of the operation of the valve and the
safety instructions to be followed. This instruction manual should be available to personnel at
all times.
This valve is suitable for use in food processes, cosmetics and pharmaceutical industry.
The following should be taken into consideration before starting up the valve/actuator:
•Check that the pipe and valve are completely free from any traces of weld or other foreign matter. Carry out
the cleaning of the system if required.
•Verify the smooth operation of the valve. If necessary, lubricate with special grease (see Chapter 6
Maintenance ) or soapy water.
•Check for possible leaks and check that all the pipes and connections are watertight and leak free.
•If the valve is supplied with an actuator, ensure that the actuator gives smooth operation.
•Check that the air pressure at the inlet to the actuator is as specified in Chapter 8. Technical Specifications
•Ensure the quality of the compressed air in accordance with the specifications described in Chapter 8 Technical
Specifications.
•Operate the valve.
4.2. OPERATION
Do not touch the moving parts of the valve when the actuator is connected to the compressed
air.
Never place fingers inside the body when you have assembled a pneumatic actuator.
Danger of burns! Do not touch the valve or pipes when hot liquids are circulating or when
cleaning and/or sterilization are being carried out.
Do not modify the operating parameters for which the valve has been designed without
written prior authorization from INOXPA.
Visually check that the sealed area has no leaks. The valves are provided with a leak detector.
The valve must be oriented so that the leak detector is visible to the plant personnel. In the
case of a leak, replace the diaphragm with a new one and clean the seal area of the actuator
of any fluid residue that may have remained.
Place the valve so that, if leakage occurs through the detector, the fluid cannot come into
contact with personnel. This is particularly relevant in the case when hot liquids are
circulating or cleaning and/or sterilisation is being carried out.
