Pneumatic single-seat regulating valve-Control valve series-调节阀厂家-上海冠环阀门制造有限公司

Product overview

Fine small pneumatic single-seat regulating valve is composed of pneumatic multi-spring film actuator and low flow resistance through single-seat valve, single-seat valve body through single-seat cover guide structure, the spool is a plunger type structure, compressed air as the power by accepting industrial signals to drive the valve stem spool operation to achieve flow control and regulation. It is suitable for the occasions where the leakage requirement is strict, the pressure difference between the front and back of the valve is low, and there is a certain viscosity and a small amount of fiber medium.

Product characteristics
1, composed of pneumatic multi-spring actuator and fine small valve body. The assembly is simple, the flow channel is smooth, and the flow coefficient is large.
2, suitable for strict leakage requirements, low pressure difference before and after the valve and a certain viscosity and containing a small amount of fiber medium occasions;
3, the sealing surface is made of stainless steel surfacing Stelli alloy, titanium and corrosion resistant alloy with wear resistance and good corrosion resistance.
