The Groth 1800A Series Full Lift Type Valve is for applications requiring low fugitive emissions and operation near tank MAWP.
A Full Lift Type Valve is a relief valve which attains full stable lift at only 10% overpressure. Like all Groth Pressure/Vacuum Relief Valves, the Full Lift Type Valve is a modulating valve which offers near zero blow down, meaning it reseats at set pressure. This technology is possible due to the harmonization of the nozzle, seating, and pallet areas such that the valve will achieve stable lift at only 10% above the set pressure/vacuum.
