Knob valves have a small travel of about 1/4 inch and can be easily operated with the palm of a hand. Knobs are constructed of sturdy black molded material. Available in spring return, pneumatic return and push-pull versions.
Operating pressure range is 0-145 PSI. Actuation force at 90 PSI: 1/8 port approx. 3.4 Lbs., 1/4 port 11.3 Lbs.
For normally open function on 3 way valves reverse connect ports 1-3. For 2 way operation, plug port 3. Panel mounting hole size for 1/8-ported valves is 5/8 inch diameter, for 1/4-ported valves, 7/8 inch. Above panel dimensions: 1/8-ported are 1" Dia. x 1.5” H: 1/4-ported -1.5" Dia. x 2.25" H.
Typical behind panel dimensions of 4 way 1/8 ported valves are 2.5" D x 1.375" W x 0.75" H; 1/4 ported valves- 4" D x 2" W x 1" H. For 3 way valves subtract 0.75" from depth. For pneumatic return add 1" to depth dimension. Allow space for fittings and tubing.
