The Enardo™ 950 vent-to-atmosphere design maintains a tight seal until system pressure or vacuum exceed the set pressure of the valve. When overpressure 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.
Features
- 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% setpoint per valve) and provides excellent setpoint accuracy (+/-3%)
- Fully field replaceable pallet and seat assemblies.
- Available in ANSI, DIN and JIS flanges
- EN 13463-1 and EN 13463-5 certified
- Optional remote monitoring
