  • Pneumatic WC6 WC9 steam control valve description

    Pneumatic WC6 WC9 steam control valve is a top entry globe type valve.The body of channel Pneumatic WC6 WC9 steam control valve is streamlined by S shape with low pressure loss, high capacity,wide regulating range, and high accuracy in flow characteristics. Pneumatic steam control valve plug features with guiding area and good vibration resistance. Pneumatic WC6 WC9 steam control valve is equipped with mult-spring diaphragm actuator and compact in structure as well as big in output force. This Pneumatic WC6 WC9 steam control valve is designed to control a broad variety of fluids, like steam, water, most of the medium and gases.
  • Pneumatic WC6 WC9 steam control valve feature

    Reduced trim can be chosen to provide wide capabilities for site applications
    Balanced trims are suitable for high pressure drop and shutoff
    Hardened trims to handle high pressure drop applications
    Bellows seal for special medium
    Extended bonnet for low temperature
    Finned bonnet for high temperature
    Higher maximum valve flow coefficients
    Bigger body volume to reduce cavitations
