Temperature proportional control valve, steam pressure control valve, electric flow control valve

First, the electronic electric control valve Overview electronic electric valve is a pressure balance valve, using the guide sleeve cage, single-seat seal structure, equipped with multi-spring actuator or electric actuators, flow channel S streamlined, Selection of imported seal ring. Whole has to work smoothly, allowing the pressure, flow characteristics of precision and low noise. Specially adapted to allow small differential pressure, differential pressure valve before and after large workplace. This series of products are normal temperature type, high temperature, low temperature, adjust the cut-off, bellows seal type and other types. Electronic electric control valve nominal pressure rating has PN1.6,4.0 6.4,10.0; body diameter range of DN20-DN300; applicable fluid temperature -150 ℃ - + 560 ℃ in the range of various grades; leak into atmosphere Ⅳ grade level, Grade Ⅴ, Ⅵ level; flow characteristics are linear, equal percentage.

High temperature valve cover additional heat sink can be used for medium temperature -60- + 450 ℃ occasions. Bellows sealed to move up and down the stem to form a complete seal, blocking absolutely fluid leakage. Low temperature plus the use of extended bonnet insulation board structure may -196 ℃ cryogenic applications. Electric temperature control valve http://www.sjv8.com
