  • Materials meet API specification 6-A & 6-D, for low temperature -46C (-50F)
  • A.C.E standard MR-01-75 for sour service
  • The Valve Ball is type 300 stainless steel, surface hardened by Nitrating to resist scratching & corrosion.
  • Various valve coatings or material options available for customer specifications
  • Seat carriers are type 300 stainless steel with seat inserts of various materials to meet specified applications.
  • The 2″ & 3″ Barber Pigging Valves have a seat supported ball.
  • The 4″ through 8″ Barber Pigging Valves have a trunnion-mounted ball to reduce low turning torque.
  • On flow line applications that transition from 2″ to 3″ or from 3″ to 4″ the larger valve can be installed to receive and send both sizes of pigs thus simplifying applications and reducing costly expenses.


  • Over-sized entry bore to accept swollen pigs
  • Entry cap vent holes to provide positive release of trapped pressure before removal.
  • Bleed valve connections (1/2″ NPT) to facilitate a choice between venting and draining
  • Integral Flanges
  • Easy shop/field maintenance.
  • Replacement parts and seal kits are readily available
  • Positive stop plate is easily repositioned 90 degrees on the operating stem to accommodate flow direction.
  • Operating stem is easily marked to verify the position of the ball
  • Cap lugs ensure that pigs are fully inserted into the ball cavity eliminating binding when rotating the valve

Enhanced Design Features

  • New seat pocket & seat design features to incorporate sealant fittings allow for on-site servicing
