The Vanessa 30.000 series valve is a quarter turn design which enables users to cover almost all the applications in which a gate, globe, ball, plug and high performance butterfly valve can be used.
The bidirectional zero leakage shut-off combined with the application flexibility of a gate valve allows operation from cryogenic temperatures to 815 deg C. The valve is metal to metal seated and inherently 'fire-safe'.
The Series 30.000 can be used for isolation and control of virtually all fluids.
