Adoptive standards:

Size Range: 2~12"(DN50~DN300)
Pressure: PN10, PN16, Class125
Body Materials: Cast Iron, Ductile Iron ;
Seat Materials: NBR, EPDM ;
Disc Materials: Ductile Iron + EPDM/NBR lined ;
Stem Materials: SS416,304
End Connection: Grooved
Operate: Manual, Worm gear, Pneumatic, Electric-Motorized
Both AS and BS standard are available.

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.
