Groth Valves for Tank Venting

Groth Valves for Tank Venting

The Groth Gas Blanket Regulator ensures that a constant gas pressure is maintained in the vapor space of a storage tank. When liquid is pumped from a tank or the temperature drops, a vacuum condition would develop. With the Groth regulator, a blanket gas is delivered to maintain the desired tank pressure. Blanket gas pressure can be maintained as low as 0.5" W.C. This reduces evaporation of stored product to a minimum and prevents the introduction of air and moisture to the tank. This conserves product and greatly reduces emissions. It also assists with providing fire protection by maintaining an inert gas environment in the tank.
