Safety Relief Valves

Description

Armstrong’s 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 capacity.
