Product overview
Single-seat regulating valve with top guide structure, equipped with multi-spring or electric motor actuators, channel was streamlined S. Has the advantages of compact structure, light weight, flexible action, small pressure drop loss, valve capacity, flow characteristics of precision, easy maintenance, 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 and cutting type, bellows seal type, jacket insulation type and other types of. Product nominal pressure level of a PN1.6, 4, 6.4, 10; body diameter range of DN20-300, a variety of grades suitable fluid temperature of -196-+560 ℃ range. Leakage level IV, V, VI. Flow characteristics are linear, equal percentage characteristics of a variety of different specifications to choose.
This series of regulating valve adopts a modular design, with different combinations, with a variety of accessories. "
