ZXP Pneumatic Diaphragm Single Seat Control Valve

With a top-guiding structure adopted and equipped with a multi-spring actuator,ZXP Pneumatic Diaphragm Single Seat Control Valve has the advantages of compact structure, light weight, motion-sensitive, streamlined channel, little loss of pressure decreasing, bulky, accurate flow characteristics, easy disassembly and so on. This product is used to regulate and control the pressure, flow and liquid level of gas, fluid, or steam media, and is particularly applied for occasions where the pressure drop is small and the medium is quite clean.
