As a key overpressure protection device for industrial pressure equipment, safety valves are indispensable in almost all industries involving pressure operation.CHOWHANG Safety Valvesseries products rely on reliable performance and strong scenario adaptability, and are widely applied in core fields such as petroleum and petrochemical, thermal power generation, metallurgical industry, urban gas, pharmaceutical and chemical industry, and new energy equipment, providing all-round safety protection for industrial production systems.

In the petroleum and petrochemical industry, production equipment and transmission pipelines need to work under high pressure and strong corrosion conditions for a long time, and the medium is flammable and explosive, putting forward extremely high requirements on the safety and stability of safety valves. CHOWHANG high-pressure pilot-operated safety valves and full-lift spring safety valves are specially designed for petrochemical working conditions. They adopt corrosion-resistant and high-temperature resistant materials, with stable pressure relief performance and good sealing effect, which can effectively avoid safety accidents such as medium leakage and explosion caused by equipment overpressure in crude oil processing, natural gas transmission and chemical reaction processes, ensuring the safe operation of petrochemical production lines.

In the power generation industry, boilers, steam turbines and thermal power pipeline systems have the characteristics of high temperature, high pressure and large pressure fluctuation range. Once overpressure occurs, it will cause serious equipment failure and production shutdown. CHOWHANG spring-loaded full-lift safety valves have fast pressure response and large-flow pressure relief capacity, which can quickly release excess system pressure when the boiler and steam system are overpressured, stabilize the operating pressure of the equipment, and effectively prevent boiler explosion and pipeline rupture accidents. The products have passed strict power industry standard tests and can operate stably for a long time in high-temperature steam environments.

In urban gas and municipal engineering fields, gas storage tanks, transmission and distribution pipelines and pressure regulating equipment are closely related to public safety. CHOWHANG micro-lift safety valves and low-pressure safety valve series products have precise pressure control and zero-leakage sealing performance, which can stably protect low and medium pressure gas systems, avoid gas leakage and overpressure explosion risks, and ensure the safe and stable supply of urban gas. In addition, the products are also applicable to water supply and heating pressure pipeline systems in municipal engineering, providing reliable overpressure protection for municipal pressure equipment.

In metallurgy, pharmaceutical, fine chemical and new energy industries, CHOWHANG provides targeted safety valve solutions according to different working condition characteristics. For high-temperature smelting equipment in the metallurgical industry, high-temperature resistant safety valve products are matched; for sterile and pollution-free production scenarios in the pharmaceutical industry, food-grade and corrosion-resistant safety valves are adopted; for new energy pressure storage equipment such as hydrogen energy and energy storage, high-precision pilot-operated safety valves are customized. With full-scenario coverage capability,CHOWHANG Safety Valvesmeet the safety production needs of various industries.
