Features & Benefits
  • Lower maintenance costs and improved equipment life span offered by the wedge design that allows for thermal expansion at high/low pressures, thereby minimizing contact between pressure loaded parts and ensuring extended seat life and sealing capability
  • Improved process integrity through performance stability and longevity by use of high strength materials, customized seat options and multiple pack offerings that meet requirements related to leakage rates and fugitive emissions
  • Highly durable and greater performance in low temperature applications through a unique cryogenic design that lowers fugitive emissions, provides leakage resistance and adheres to fire safety standards”


  • Cryogenice design for Temperature up to -320°F to meet BS 6364 seat leakage requirements
  • Special low-torque cryogenic seat profile

Designed for temperatures up to +1500°F for highest demands on valve tightness in process and to atmosphere (FE)


  • Cost effective trunnion mounted sealing systems in size range 6"-16" in a wedge design for a consistently clean finish product
  • Smaller sizes covered by floating ball design.In-line maintenance and repairability
  • Lower torque for installation of cost effective actuators
