Product Overview:
Foot valves are consists of valve body,bonnet,disc,sealing ring and gasket etc parts.The disctypes are divided in to single disc,double disc and multi-disc.After installing the foot valves on the pipes,medium flow to the body from bonnet.The liquid pressure act on disc to make it open.When the medium pressure in body change er disappear,the disc will close to prevent medium backflow."

Inspection and 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.
