Features

  • The actuator/valve assembly action can be converted from push-down-to-open to push-down-to-close, or vice versa, without additional parts.
  • Both the metal and soft seal rings have pressure-assisting sealing action that ensures tight shutoff regardless of pressure drop.
  • Standard valve construction includes conductive packing to provide electrical bonding for hazardous area applications.
  • The valve will operate at elevated temperatures, with the appropriate trim components.
  • Additional travel indication can be achieved by using the indication line on the shaft, along with the disk position markings on the packing follower.
  • Redundant shaft retention provides added protection. The packing follower, anti-blowout ring, and shaft groove interact to hold the shaft securely in the valve body.
