SMC 639 Series Three-Way Ball Valve


Design Considerations

  • The 639 Series Valve is 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.

  • The handle can be orientated in four positions and can be installed or removed while the valve is under pressure.

  • The panel mount requires a 0.750"hole through a maximum panel thickness of 0.170".

  • Two of the four available screw boss locations will secure the valve.

  • Panel mount screws are not supplied.
