Product Overview:


Adopt double number guide structure, with multi spring holding mechanism. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient disassembly and assembly. Widely used in the accurate control of gas, liquid, steam and other media process parameters such as pressure, flow rate, temperature, liquid level to keep in the given value. Especially suitable for large pressure difference, allow leakage is also large and not very clean medium occasions.
ZMAP pneumatic film through single-seat regulating valve, ZMAN pneumatic film through two-seat regulating valve products have standard type, bellows seal type, jacket insulation type and many other varieties. The nominal pressure grade of the product is PN16, 40, 64; Valve body caliber range DN25 ~ 400. Applicable fluid temperature range of -250ºC ~ +560ºC in a variety of grades. The leakage standard is3grade and 4 grade. Flow characteristics are linear or percentage. A wide variety of specifications are available.
