Manual control valve | Mastery ventilation equipment factory (certified) | valve

 One of the development process of regulating valve: regulating valve development has been eight years of history since the initial valve factory of the 20th century, has produced a ten categories of regulating valves, self-operated valves and positioners, etc., in the 1920s : The original stable pressure regulating valve used to come out. 1930s: in a "V" notch valve seat and single seat valve for regulating valve V-representative products available. 1940s: the emergence of positioning, control valve further improved new varieties. After the self-pressure regulating valve without external energy regulator, the use of the medium itself was transferred energy as the power source, the introduction of the actuator control valve spool position manually change the pressure and flow control valves at both ends of the specifications, the front valve (or valves ) pressure stability. A sensitive, tightness, pressure set-point fluctuations, etc, are widely used in gas, liquid and steam medium voltage vacuum regulator or relief automatic control. This series has a pressure regulator before the role of type (B-type) and pressure relief valve pressure regulator (K-type) after decompression valve. Pressure segment is adjustable from 15 ~ 250KPa. May need a combination of conditions to meet user requirements. Manual control valve | Mastery ventilation equipment factory (certified) | valve provided by the Texas Mastery ventilation equipment.
