Plast-O-Matic Series MFR 1/2" and 3/4" palm or foot valves are the answer for handling pure deionized rinse water where your hand or hands must be free to handle the part being rinsed. They are also ideal for handling corrosive or other ultra-pure liquids where economical performance is a prime consideration.

Design:

Series MFR self-closing valves are normally closed and require a minimum of palm, foot or knee pressure to open. Double U-cup seals are used on the shaft to isolate the spring from the liquid. The U-cup seals in conjunction with a poppet seat at the valve orifice results in a non-sticking design. For mounting the valve securely to a bench or floor, four 1/4-20 tapped screw holes are provided in the base of the body. A plastic foam seal under the activating button prevents dirt and dust from entering into the top spring area.
