Groth Pilot Operated Relief Valves
Product Overview
Pilot operated relief valves use tank pressure to keep the valve seat closed and are typically used when operating close to the MAWP. As pressure rises, the plate force overcomes the spring force, causing the dome to leak and the valve to open. POVs reduce risk not only by relieving tank pressure but also help keep you compliant with strict environmental regulations. They also improve efficiency by controlling losses due to evaporation. Groth offers two types of pilot operated relief valves, the 1600 series and the 1400 series.
