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