Two-seat valve is a pressure balance valve, the cage-type sleeve guide, single-seat sealing structure, equipped with multi-spring actuator or electric actuator, flow channel was streamlined S, imported seal ring. Overall with stable, allowing a large pressure difference, flow characteristics of precision low noise characteristics. Especially suitable for not high, requirements on the leakage of valve and pressure of work.
This series of products are the normal temperature, high temperature, low temperature, regulating and cutting type, bellows seal type and other types of. Product nominal pressure level of a PN1.6, 4, 6.4; body diameter range of DN20-DN300; a variety of grades suitable fluid temperature of -150 ℃ -+560 ℃ range; leakage level atmosphere is divided into grade IV, V; linear, equal percentage flow characteristics. Available in various sizes.
This series of regulating valve adopts a modular design, with different combinations, with a variety of accessories. "
