Features:

1. Small in size and light in weight. Easy to install and maintain.Can be installed wherever needed.
2. Simple and compact construction, 90 ° rotating ,open and shut rapidly
3. Small operating torque, energy saving.
4. Discharge characteristic tend to straight line,good regulation performance.
5. Completely sealed, zero gas leakage test
6. The number of open and close test reaches as many as tens of thousands of times, long service life.
7. Applicable to a variety of medias when using different materials.

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.
Special Test: On request, any other test can be carried out according to special instruction by client.
