ZOBAI Valve Ltd.
The pilot-operated safety relief valve is a safety valve with a novel structure. Mainly used in fields such as oil and gas, chemical industry, electric power, metallurgy and city gas, it is the best overpressure protection device for pressurized equipment, containers or pipelines. Its main advantage is that the direct action of the spring is changed to the indirect action of the pilot valve, which improves the sensitivity of the action. The main valve adopts a sleeve piston type, which has high action accuracy, good repeatability, high seat back pressure, good sealing performance, and can carry high back pressure. It has high pressure discharge, stable and reliable operation, can be adjusted online, and is easy to operate and maintain.
