Circle Seal Controls 500 Series Relief Valves Product Leaflet
The 500 Series Adjustable Popoff & Inline Relief Valves provide over‑pressure protection for a wide range of systems. They use a resilient seal design that prevents leakage and a metal‑to‑metal poppet that opens when system pressure exceeds the set cracking pressure, allowing controlled flow.
These valves are suitable for storage tanks, refrigeration, medical equipment, pumps, and many other applications. The leaflet includes technical data, flow curves, material options, connection sizes, and ordering instructions, along with safety and certification information.
