Premium performance product

Features

 

  • ISO 5211 mounting pad for direct mounting of handle, gear operator, manual override, or actuator
  • An extremely tight fit square drive between the stem and disc provides accurate and repeatable shut-off and control
  • Bonded seal is the most rugged method of construction available, providing consistent operating torque, maximum cycle life, and higher flow velocities in control. Avoids pinching and tearing that can occur with non-bonded seal designs
  • Bonded seal is easy to remove and replace if maintenance is ever needed
  • Disc is precision machined with a spherical disc edge to provide long cycle life
  • Two-piece stem arrangement for highest Cv and maximum flow
  • Top and bottom stems have anti blow-out protection that also prevents lifting or pushing of the disc during actuator installation or removal
  • Lower stem includes groove for easy servicing
  • The burnished stem is supported by self lubricating polymer bearings to minimize deflection and provide smooth operation and long life

 

Benefits

  • Long cycle life
  • Direct actuator mounting capability
  • Easy to maintain
  • Two-piece stem for highest Cv
  • Various materials of construction available for wide range of applications
