SMC 629 Series Three-Way Ball Valve

Design Considerations

• The bottom port is common and the 629 can be used as a diverter or selecting valve.

• The handle has 180 degree rotation and lies over the open port.

• When the handle is rotated 90 degrees from either port, flow is shut off to both ports.

• The T-Handle and Ball are one piece extending through the valve body and sealed on the top and bottom.

• The colored handle center indicates the seal material:

Black = Buna-N

Red = EP

Blue = Fluoroelastomer (Viton®)

• PVC with Buna-N or Ethylene Propylene seals is NSF Standard 42 Certified.
