The VTR ASME Series is a forged trunnion mounted ball valve that offers a large range of applications. It features a 3-piece body construction and uses C-RPTFE seats for maximum chemical compatibility combined with minimum coefficient of friction. It is a bi-directional, single piston effect, zero leakage valve and has an ISO 5211 top works, which simplifies the actuator and gear operator mounting. It is available in up to CL2500. The high-quality forgings makes it a reliable solution for the toughest requirements.
