Plast-O-Matic Valves, Inc. - Unique Valve for Fill, Rinse, Spray Applications

Series MFR manual valves require palm, knee, foot, or elbow force to open and close automatically once the force is released due to an internal spring. The stainless steel spring is not in the liquid. Double U-cup seals are used on the internal shaft for low friction and long cycle life. This in conjunction with a poppet seat at the valve orifice results in a non-sticking design. (read more)
