Prominent multi function valves are a combined relief and back pressure valve that fits directly onto the pumps dosing head. The back pressure valve creates a uniform backpressure that helps to maintain precise metering and protects against inaccuracy. The valve is easy to operate using two rotary dials either side that return to the original position when released. Suitable for use with almost any chemical.
