The new ZXG series of films through single seat pneumatic control valve driven by the top structure, equipped with multi spring actuator. The advantages of compact structure, light weight, flexible action, fluid channel is S streamline, pressure drop loss, large valve capacity, accurate flow characteristics, convenient assembly and disassembly, etc.. Widely used in precise control of gas, liquid and other media, process parameters such as pressure, flow, temperature, liquid level is maintained at a given value. Particularly suitable for the small amount of pressure difference before and after the leakage of small valve.
This series of products of the standard type, regulating cut off type, bellows seal type, jacket insulation type and other varieties. Product nominal pressure level is PN10, 16, 40, 64; body diameter range DN20~200. Applicable fluid temperature range from -200 to ~560. Leakage standard has IV or VI level. The flow characteristic is linear or equal.
