Description
Designed to provide overpressure relief for large cryogenic storage volumes; enables emergency capacities protecting against adverse conditions.
- Large orifice area reduces dramatically the number of valves needed to provide safety.
- O-ring seat provides bubble-tight performance to 90% of set pressure.
- A combination of tension link and spring force holds the valve closed to provide positive opening at set pressure and bubble tight shut-off at reseat.
- Full open at set pressure with no overpressure required for rated capacity.
- Flange mounting with a flat face, smooth finish.
- Reseat pressure is 50% of set.
