Description

SS Relief Valves Supplied by HA Tradings

At HA Tradings, we supply premium SS relief valves sourced from verified and trusted international manufacturers, engineered to safeguard industrial systems by relieving excess pressure in gas and liquid applications. Designed for B2B bulk buyers, these valves ensure corrosion resistance, rapid response, and compliance for enhanced safety and efficiency.

Key Specifications & Technical Standards

Our SS relief valves meet stringent global standards including ASME Section VIII, API 520/527, and ISO 4126, ensuring reliable overpressure protection. Constructed from SS316 or SS304 for bodies, discs, and springs, available in sizes from 1/2″ to 6″ (DN15 to DN150) with threaded (NPT) or flanged ends (ANSI B16.5). Rated for set pressures up to 1500 PSI (103 bar) and temperatures from -46°C to 350°C, featuring pop-action or proportional lift designs. Equipped with PEEK or metal-to-metal seats for zero leakage and adjustable blowdown settings. Safety includes manual test levers and bellows for backpressure compensation. Each valve undergoes set pressure testing, seat tightness checks per API 598, and certification by TUV or NB, compliant with UAE pressure safety and NACE MR0175 for sour service.

Features & Benefits for Bulk/Industrial Buyers
