Vanessa, triple offset rotary process valve

Vanessa valves has a torque generated elastic metal seal provides zero leakage performance as from API 598 & API 6D. Torque seating ensures continuous bi-directional zero leakage performance.
Quarter turn non-rubbing design is achieved by unique triple offset geometry, completely eliminating all seat to seal rubbing throughout the valves 90 degrees rotation.
Stellite hardfaced standard integral seat results in broader applications, longer valve life and less maintenance.
Single-piece cast body with face-to-face in acc to ISO 5752, ASME B16.10 and API 609 provides interchangeability with gate, high performance butterfly, plug and other valvesfor simpler and more flexible installation.
SIL approval IEC 61508 (ESD applications) and can be delivered as a package with SIL approved actuator and solenoid valve and/or positioner.
