  • 90 deg rotation
  • 200 psi close off
  • 75 deg controllable flow range
  • Thermal isolating adapter between flange and actuator
  • Easy direct coupling of actuator with a single screw
  • Perpendicular mounting flange and square drive head eliminate lateral forces on the stem
  • Blow out proof stem with thrust bearing teflon disc and double o-ring design for long service life
  • Stainless steel ball
  • Vent holes reduce condensation build-up
  • Forged brass valve body - no pin hole leaks
  • Characterizing disc made of Tefzel® known for excellent strength and chemical resistance
  • Teflon seats with o-rings provide constant seating force against the ball and reduce torque requirement
  • Actuator can be mounted in four different positions
  • Equal percentage flow characteristic
  • Excellent control stability assured with the characterizing disc
  • Cv values equal to Cv values of globe valves the same size
  • The need for multiple pipe reduction is usually eliminated
  • Better control prevents “hunting” of the control loop, increasing life span of actuator and valve
