Description
Henry Standard Range pressure relief valves are designed to protect refrigeration system components from dangerous overpressure conditions. These safety devices automatically discharge vapor when pressure exceeds the preset limit, then reseat once safe pressure levels are restored. Manufactured with precision‑machined components and a non‑stick, chemically inert PTFE seal, Henry PRVs deliver reliable, repeatable performance and long service life. Valves are factory set, tamper‑proof, and maintenance‑free. Brass and stainless steel construction options are available, with multiple connection sizes and pressure settings to suit a wide range of applications. Henry pressure relief valves are suitable for use with common refrigerants including HFC, HCFC, HFO, CO₂, R290, and—with stainless steel models—ammonia where materially compatible. Common applications include receivers, vessels, heat exchangers, and other refrigeration system components requiring dependable overpressure protection.
