Pneumatic single seat regulating valve

2025-06-03

Pneumatic single seat regulating valve is a key equipment in industrial fluid control systems, which uses compressed air as power to achieve precise control of medium flow rate, pressure, and liquid level. This valve adopts a single seat valve core structure with excellent sealing performance. The metal seal leakage is only 0.01% of the rated flow rate, and the soft seal can even achieve zero leakage, effectively avoiding medium overflow. During operation, the pneumatic actuator receives a 4-20mA standard signal and converts it into air pressure through a locator, driving the valve core to move up and down and quickly responding to system commands. The adjustment accuracy can reach ± 1%. Its streamlined flow channel design greatly reduces fluid resistance, has excellent flow capacity, and is resistant to high pressure, corrosion, and can adapt to harsh working conditions such as high temperature and strong corrosion. Widely used in industries such as petrochemicals, power, metallurgy, etc., in scenarios such as boiler steam pressure regulation and chemical raw material ratio control, it ensures safe and efficient operation of the production process with advantages such as strong stability, good explosion-proof performance, and easy maintenance.
