Oval trip-proof handle helps prevent accidental actuation.
Quarter turn handle provides a visual indication of on/off valve position, improving safety
Blowout-proof stem for added safety
Dual encapsulated TFE seats and microfinished ball ensure a leak tight seal. This combination provides greater valve reliability.
Floating ball provides pressure-assisted sealing and temperature wear compensation for longer valve cycle life and greater value.
TFE seats with TFE or Viton® washers provide excellent corrosion resistance, providing the correct material for the application.
A wide variety of HOKE Gyrolok® end fittings and pipe fittings provide the correct fitting option for the application.
