Brief Description

AJL Pressure Relief Valve (soft‑seal ball structure) is designed for overpressure protection and safe pressure release in ball valves, gate valves, and wellhead equipment for the oil, gas, and water treatment industries. It features a 316SS/304SS body, INCONEL X-750 spring, and PEEK seal, with a working pressure up to 10000 PSI. Standard connections include 1/4-18NPT, 3/8-18NPT, 1/2-14NPT, 3/4-14NPT, and 1-11.5NPT. Customization is available, and it is equipped with a safety lead wire for reliable pressure release under severe conditions.

Detailed Description

AJL Pressure Relief Valve (PRESSURE RELEASE VALVE) is a core safety component for the oil, natural gas, and water treatment industries. It is specially designed for pressure control systems of ball valves, gate valves, and wellhead equipment, automatically opening to release pressure when system pressure exceeds the set value, ensuring equipment and personnel safety.

Key Advantages

High-Performance Materials

The body is made of 316SS/304SS stainless steel (customizable), the spring is INCONEL X-750, and the seal is PEEK. It offers excellent corrosion resistance, wear resistance, and high‑temperature resistance, suitable for various harsh working conditions.

High Pressure & Reliable Relief

The soft-seal ball structure has a rated working pressure of ≤10000 PSI (approx. 68.9MPa). It has passed strict pressure tests to ensure accurate opening and stable pressure relief under overpressure conditions, eliminating the risk of leakage and failure.

Safety Structure Design

Equipped with a safety lead wire that can be linked to safety systems to prevent misoperation. The relief pressure is clearly marked on the valve body (MARK RELIEF PRESSURE) for easy on‑site identification and maintenance.

Flexible Connection Options

Standard ports include 1/4-18NPT, 3/8-18NPT, 1/2-14NPT, 3/4-14NPT, and 1-11.5NPT. Non-standard customization is supported to match various wellhead equipment and valve connections.

Applications

Widely used in oil drilling platforms, natural gas long-distance pipelines, oil and gas processing plants, industrial water treatment systems, and other fields. As a supporting safety relief valve for core equipment such as ball valves, gate valves, and wellhead Christmas trees, it undertakes key tasks such as overpressure protection and pressure release, ensuring the safe and stable operation of industrial systems.
