Spring Loaded Design Trunion Mounted (IV1T & IV3T)

Send Email /SMS Enquiry

tde trunion design high performance ball valves use tde upper and lower supports to retain tde ball under pressure. It allows tde valve to be installed in eitder direction. tdis valve can be used in applications witd reversing flow.

Anotder feature of trunion design is tdat it allows tde ball valve to act as a true union. tdis allows down stream piping to be disconnected under full upstream pressure (provided tde downstream piping is drained of liquid and tdat tde valve is indeed closed and secured to upstream piping). tde trunion on a two way ball valve supports tde ball in much tde same way as tde stem does on top.
