Pump Valve Rubber Diaphragm for Pneumatic Valves and Cylinders

Diaphragm parameters of pneumatic control valve:

Diameter: 5-1500mm
Material: Nitrile rubber natural rubber
Temperature Resistance: -35° C to 300° C
Tensile strength: ranging from 0.1 to 15Mpa

The installation steps of the pneumatic valve diaphragm are as follows:

1. Put the spring on the spring seat.
2. Install the diaphragm. When the diaphragm and the hard core are fixed, a loosening pad should be added to the screw cap to ensure that the diaphragm is flat and air-proof.
3. Therefore, grease should be applied to the fastening bolts before assembly, which is conducive to the next maintenance and lubrication.
4. Put on the upper membrane cover, fix it with a pair of eyebolts, and evenly and alternately tighten the eyebolts to complete the initial adjustment of the spring.
5. Tighten the fixed explosion nut on the membrane cover, and do not screw the eyebolt.
6. Install the connecting parts, and connect the supply line to the upper membrane cover.
7. After the above steps are completed, apply the following methods to verify:
1) Through the air supply line, the membrane air chamber is passed into the air supply pressure of 500KP, and use soapy water to check whether there is air leakage around the membrane.
2) Check whether the execution is flexible within the full stroke range (referring to the actuator itself).
