Design Considerations
  • The 639 Three-Way Ball Valves feature Black Glass Filled Polypropylene as the standard material
  • Designed as a panel mount diverter valve, the middle port is common
  • The 90 degree handle rotation directs the flow to the open port, shutting off the other port completely
  • There is no point in the handle rotation where flow is shut off to both ports at the same time
  • Handles can be orientated in four positions and can be installed or removed while the valve is under pressure
  • Two of the four available screw boss locations will secure the valve
  • Panel mount screws are not supplied
