To meet the diverse working condition requirements of different industrial fields, CHOWHANG has developed a complete series of safety valve products, covering mainstream types such as spring-loaded full-lift safety valves, spring-loaded micro-lift safety valves and pilot-operated safety valves. Each type of safety valve has unique structural design and functional advantages, targeting specific medium types, pressure ranges and application scenarios, providing precise overpressure protection for industrial equipment. This article will systematically introduce the core characteristics and applicable scenarios ofCHOWHANG Safety Valvesmainstream series.

First, CHOWHANG spring-loaded full-lift safety valve is one of the most widely used conventional safety valve products. This product adopts a spring direct-acting structure, with a simple and stable mechanical principle and high operational reliability. It can realize full-lift rapid pressure relief after reaching the set pressure value, with large pressure relief flow and fast response speed. It is suitable for gas, liquid and steam medium systems, and is widely used in pressure vessels, boilers, heat exchange equipment and pipeline systems in chemical, power and petroleum industries. The product supports multi-specification customization of pressure level and caliber, and all key parts are precisely processed to ensure accurate opening pressure and stable reset performance.

Second, the spring-loaded micro-lift safety valve launched by CHOWHANG is specially optimized for liquid medium working conditions. Different from full-lift products, the micro-lift safety valve only lifts slightly to release pressure when overpressure occurs, with small flow regulation and gentle pressure relief process, which can effectively avoid system pressure fluctuation caused by rapid pressure relief. It is mainly applicable to various liquid medium pressure pipelines and storage equipment in pharmaceutical, food, light industry and petrochemical industries. The product has excellent sealing performance, effectively preventing liquid medium leakage, and has low maintenance difficulty and long service life.

Third, CHOWHANG pilot-operated safety valve is a high-precision and high-performance upgraded product. It abandons the traditional spring direct-acting mode, and adopts pilot valve indirect control and sleeve piston type main valve structure. This innovative design greatly improves the action sensitivity and pressure control accuracy of the safety valve, with ultra-high repeatability of opening and closing pressure. The double-sealed valve seat structure realizes zero leakage under rated working pressure, which is more energy-saving and environmentally friendly. It is suitable for high-precision pressure control scenarios such as high-pressure petrochemical equipment, natural gas transmission pipelines and industrial precision pressure systems, and can adapt to complex working conditions with strict pressure fluctuation requirements.

AllCHOWHANG Safety Valvesare standardized in production and customizable in parameters. Customers can select matching products according to medium type, working pressure, temperature range and equipment parameters, and obtain professional type selection technical support from the team to ensure that the safety valve perfectly matches the actual working conditions.
