950 PVRV Vent-to-Atmosphere

Main Features

Vent to atmosphere at the end of the pipe
Advanced composite thermoplastic Polyphenylene Sulfide (PPS) materials for seat and pallet provide superior resistance to corrosion, chemical attack, liquid and vapor adhesion, temperature extremes (-50 to 500°F) and sticking due to valve seat freeze
Enardo Saber® Guide valve system provides for smooth valve stroke during operation and reduces valve wear
Exceeds the most stringent standards for allowable leakage (1 SCFH at 90% set point per valve) and provides excellent set point accuracy (+/-3%)
Fully field replaceable pallet and seat assemblies.
EN 13463-1 and EN 13463-5 Certified
Optional Remote Monitoring

Applications

Vent-to-atmosphere design maintains a tight seal until system pressure or vacuum exceed the set pressure of the valve. When over pressure occurs the weighted pallet lifts, breaking the seal between the seat and pallet, allowing vapors to pass through the valve orifice and relieving the pressure or vacuum buildup. The valve reseals upon relief and remains sealed.
