Single Seat  Control Valve top guide plunger valve core, floating compression sleeve, self centering valve seat structure, modular design. Large circulation capacity, high adjustment accuracy, wide adjustable range, capable of achieving minimal flow control, simple and reliable structure, good sealing performance, and easy on-site maintenance. Suitable for situations with small pressure difference, high requirements for valve seat leakage and control accuracy.

Performance characteristics：
1. Composed of a pneumatic multi spring actuator and a precision small valve body. Easy assembly, unobstructed flow channel, with a large flow coefficient;
2. Suitable for occasions with strict leakage requirements, low pressure difference before and after the valve, certain viscosity, and a small amount of fiber medium;
3. The sealing surface adopts stainless steel surfacing Stellite alloy, titanium and corrosion resistant alloy, which have good wear resistance and corrosion resistance;
4. The temperature can be selected from -20 ℃ to 200 ℃, -40 ℃ to 450 ℃, and -40 ℃ to 540 ℃ based on actual usage.
