  • Description:
  • Pneumatic eccentric rotary plug control valve Feature

    Pneumatic eccentric rotary plug control valve(also called camflex control valve) is a novel structure control valve. The gyration center of plug of Pneumatic eccentric rotary plug control valve is not concentric with rotary axis, which can ensure the reliable sealing and prolong the service life with a designed eccentricity. Also Pneumatic eccentric rotary plug control valve has the characteristics of small size , large flow capacity, wide adjustable range, good sealing performance, large pressure drop applicable, wide temperature range applicable and so on. The control valve equipped with pneumatic or electric actuator can meet various requirements of fluid control which is mainly used in the occasions of large viscosity and medium with solid.
  • Pneumatic eccentric rotary plug control valve Feature

    · Integrated valve body (cast with bonnet) design, no static or dynamic sealing except shaft seal
    · Double offset structure design, no "detachment effect" between the seat and plug
    · High fluid capacity and range ability for heavy duty industrial design
    · Decompress the liquid by inserting multi-hole plate in to the main body
    · Built-in type and the combined external type multi-hole plate
    · Heat jacket and erosion-proof treatment for crystallizable medium
    · Easy replacement of rotary, symmetrical plug and actuator
    · Metal seat for Class IV shut-off and Soft seat for Class VI shut-off
    · Accessibly connected actuator from outside, which the actuator pivots to axis of valve
    · Double sealing system between shaft and bonnet, which makes low leakage (equal to TA-Luft condition)
