Features & Benefits	Quarter turn handle provides a visual indication of on/off valve position, improving safety. Dual encapsulated TFE seats and microfi nished ball ensure a leak tight seal. This combination provides greater valve reliability. Dyna-Pak packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions. Floating ball provides pressure-assisted sealing and temperature wear compensation for longer valve cycle life and greater value. A wide variety of Hoke Gyrolok end fittings or pipe fittings provide the correct fi tting option for the application. Special High Tolerance NPT Thread
