Standard Test

Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

 

Seat Test: 1.1 times the working pressure with water.

Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.

 

Features:

1. Small in size, light in weight, easy installation and maintenance.

2. Simple and compact construction, quick 90 degree on-off operation.

3. Minimized operating torque, energy saving.

4. Flow curve tending to straight line, excellent regulation performance.

5. Long service life, standing the test of tens thousands opening/closing operations.

6. Wide selection of materials, applicable to various medium.
