FEATURES

  • Non-rotating stem plug moves axially into and out of the seat without rotation to eliminate seat galling.
  • All bonnets are assembled with a locking pin to prevent accidental removal while in service.
  • The stem threads are rolled and lubricated to prevent galling and reduce operating torque.
  • Stem packing is below the thread to prevent thread from lubricant washout and secure no process contamination.  This ensures smooth valve operation and long service life. 
  • Valve seat and stem tip are particularly finished to extend service life.
  • Body to bonnet seal is metal to metal in constant compression, creating a reliable seal point to eliminate possible tensile breakage of bonnet and isolate the bonnet threads from process fluid corrosion.
  • Dust caps are fitted to contain stem lubricant and prevent the ingress of contaminants.
  • Low torque operating T bar handle
  • Optional panel nuts are available to secure valves to instrument panels.
  • All valves are hydrostatically tested to 1.5 times maximum working pressure prior to shipment.
  • The valves are heat code traceable.
