Test Specification:
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: 1.5 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

Butterfly Valve Applications: Water Treatment Plant, Paper Industry, Sugar Industry, Breweries, Chemical Industry, Waste Effluent Treatment Plant, Drilling Rigs, Gas Plant, Cooling Water Circulation, Heating & Air Conditioning, Pneumatic Conveyors, Compressed Air
