316 Stainless Steel 3 Piece Ball valve with full bore and NPT threaded end connections. This high performance valve is suitable for many applications such as the water, chemical, petrochemical, marine and general industries. With an ISO pad and Lockable Lever, this makes this valve a versitile fit for many applications, whether by Manual Lever or Actuator / Gearbox.

  • NPT Threaded End Connections, Length to DIN3202-M3
  • Reinforced PTFE Seats suitable for a wide range of media and temperatures up to 180°C (Refer to Pressure Temperature Curve and Material Data sheets for Chemical Compatibility). 50% Stainless Steel & 50% PTFE seats available as an option for higher temperature service
  • Self Adjusting Stem Packing by the use of Belleville washers which assist with temperature fluctuations and vibrations.
  • ISO5211 Mouting pad with holes pre drilled to Metric sizes to support a range of actuators
  • Vented design on the Neck of the Valve allows for a reduction in thermal transfer from the valve to the actuator
