Design Considerations
The 734 Ball Valve Series is designed to promote multiple configurations to fit the exact end use in 1/8" and 1/4" applications. The 734 Four-Way Series can be used as a diverter or selecting valve. The Valve stem is sealed with two o-rings and a TeflonŽ Packing. The Ball has two independent 90 degree holes that connect adjacent ports. The handle has 90 degree rotation and lies over the open port. When the handle is rotated 90 degrees from either port, flow is connected to the alternate ports. The 734 has a large Black Nylon Knob as the standard handle. The required Panel Mount Hole is .562. The maximum panel thickness is .175.
