Grundfos Multi function valves

Product description

The Grundfos multi-function valve with two diaphragms for dosing pumps up to 60 l/h combines four functions – pressure loading, pressure relief, deaeration and drain. Directly mounted on the discharge valve of the pump, the multi-function valve simplifies the handling of the pump and ensures process reliability.

If the system has not enough backpressure, the multi-function valve maintains the backpressure at the level which is necessary for the pump. Moreover it protects the pressure side dosing line system from too high pressure build-up. The pump can be deaerated and the pressure-side piping system can be drained via the multi-function valve.
