Vanessa™ Series 30,000 Triple Offset Valve for Gaseous Oxygen (GOX)
This Vanessa Series 30,000 Triple Offset Valve configuration features a full metal construction, frictionless trim rotation, and torque seating. This, combined with innovative material selection and a dedicated manufacturing process, ensures outstanding isolation and control functions at high pressures in gaseous oxygen (GOX) applications.
Features
- Robust, fire-resistant, inherently antistatic all-metal construction.
- Burn-resistant Stellite® grade 21 seat overlay provides excellent durability.
- Die formed packing rings, obtained from Sigraflex® unreinforced foil, are oxygen compatible and oxidation resistant.
- Two-piece packing gland minimizes external emission risk.
- Nitronic® 50 round solid seal ring (or copper beryllium alloy in case of Monel valve body) with molybdenum disulfide dry antifriction coating tested for oxygen compatibility.
- Robust one-piece shaft is designed to transfer/maintain torque efficiently.
- Key secured shaft-to-disc connection ensures maximum shaft integrity.
- Handling of shaft extrusion risk in compliance with international standards.
- Spot-faced flanges ensure maximum joint-to-pipe integrity.
- Screw securing ring eliminates risk of in-pipe screw dispersion.
