The Series MFR 1/2-inch-size palm or foot-operated shut-off valve has no metals or external fasteners, making it suitable for high-purity or corrosive environments. The balanced, compact valves are designed for liquid service to 150 psi. The balanced aspect means that the valve outlet pressure, commonly known as back pressure, can be as high as the inlet pressure without affecting performance. The normally closed design has a spring return and will automatically close fail-safe when hand or foot force is removed. Valves are available in Grade 1 Type 1 PVC or natural polypropylene for heavy-duty applications.
