1.Pneumatic single seat control valve Product overview

Pneumatic diaphragm control valve with top guide structure, equipped with multi spring actuator, flow channel was streamlined S. Has the advantages of compact structure, light weight, flexible action, small pressure drop loss, valve capacity, flow characteristics of precision, convenient maintenance and so on, can be used in harsh working conditions. Particularly applicable to allow a small amount of leakage, the valve before and after the pressure is not the occasion. This series of products are the normal temperature, high temperature, low temperature, regulating off type, bellows seal type, jacket insulation type and other types of. Valve caliber range is DN20-300, a variety of grades suitable fluid temperature range of -196-+560 ℃. Leakage level IV, V, VI class. There is a straight line, the percentage of properties such as flow characteristics. A variety of different specifications are available.
