Emerson Fisher 1/4 in. MNPT External Relief Valves for Hydrostatic Containers – 450 PSIG

Description

Emerson Fisher 1/4 in. 450 PSIG, MNPT External Relief Valves for Hydrostatic ContainersUL Listed external relief valves used on Hydrostatic containers. The relief valve is held close by the spring force seating the rubber valve disc against the orifice. When the tank pressure exceeds the spring force, the valve disc lifts off the orifice allowing gas to discharge through the valve to the air. When the tank pressure decreases enough, the spring force closes the valve disc back against the orifice stopping further discharge. All working parts of theses valves are outside the container connection so they must be protected against mechanical damage.This product is backed by a 10 year warranty.FeaturesSpace Saving Construction: Small relief valve size allows installation where space is limitedEconomical: Low initial cost, easy installation, and high capacity per dollar invested reduces total cost of having relief valve capabilities in your systemDurable: Brass body construction and stainless steel spring reduce susceptibility to corrosion damage and the preset, pinned spring retainer prevents relief valve setpoint tamperingSpecificationsContainer Type: HydrostaticContainer Connection: 1/4 in.
