Safety Relief Valves


safety relief valves for refrigeration service are designed to provide
emergency relief from excessive pressure in refrigerant containing
vessels. These tamper-resistant valves are accurately set and sealed by
qualified technicians at the factory.

Our safety valve design features the most reliable method of safely
relieving pressure. The Teflon seal combined with a stainless steel
crown ring provides outstanding sealing action. This combination assures
a non-stick and accurate pop-off pressure release. The design
incorporates an extra lift and pop-open feature for high-relieving
