July 7, 2009 - PRLog -- GROTH CORPORATION INTRODUCES THE NEW FULL LIFT TYPE VALVE AT 10% OVERPRESSURE

Liberty, Missouri – July 7, 2009 - Groth Corporation announces the new 1800A Series Full Lift Type Valve at 10% Overpressure for applications requiring low emissions and operation near tank Maximum Allowable Working Pressure (MAWP).

A Full Lift Type Valve is a relief valve which attains full stable lift at only 10% overpressure.  This new valve is a modulating valve offering near zero blowdown and reseats at near set pressure.  Operating within 10% of the tank MAWP greatly reduces the breathing losses of the product in the tank.

The Groth Corporation 1800A Series Full Lift Type Valve performs better than the API Bulletin 2521 and ISO 28300 seat leakage requirements.  Available in 2” (DN 50) through 12” (DN 300) flange sizes, the 1800A Series valve provides the user with reduced vapor emissions and better tank corrosion maintenance.

Established in 1960, Groth Corporation is a global leader in manufacturing pressure/vacuum relief valves, deflagration and detonation flame arresters, blanket gas regulators, and other low pressure relief products. Groth pressure relief products have been protecting refineries, chemical processing plants, and facilities with atmospheric storage tanks for more than 40 years.
