Product overview
Three points ($) flow control valve with double valve on the lower guide structure, equipped with pneumatic or electric actuator actuator, valve three
Through the structure, namely the one into two (shunt), two into a (confluent), so as to achieve the fluid mixing heating or cooling, or fluid not equivalent shunt, meet the demand of different industrial requirements. The valve has the advantages of compact structure, light weight, flexible action, small pressure drop loss, valve capacity, flow characteristics of accurate and convenient repair. Can be used in variety of working conditions, automation control system of temperature control system is especially suitable for the oil industry, heat exchangers and other various industries.
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, VI; 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. "
