MPBT Medium Pressure Trunnion Ball Valves

Brand: Bifold - by Rotork
The bifold range of medium pressure trunnion ball valves have been developed to the highest quality for uppermost performance. 

They are available in a wide range of configuration for most liquid service applications up to 20,000 psi / 1,379 bar. 

An extensive range of seal materials available, which are suitable for extreme environments.
Features
  • Blow out proof stem design
  • Maintenance free stem sealing
  • Low operating torque
  • Pressure loaded seats creating a positive seal
  • Bi-directional straight through flow path minimizing pressure drop
  • High tensile 316L CW stainless steel bodies as standard
  • Glass reinforced PEEK seats as standard for excellent chemical resistance
  • Exotic materials available upon request
  • Traceability via a unique serial number stamped on the valve body, Gland and collar
  • Available in a number of temperature ranges from -46° to 225°C (-20° to 180°C as standard)
  • Nace MR-01-75 / ISO 15156 compliant materials of construction are available upon request
