Diaphragm valve WW-750-66 EN/ES

hydraulichydraulically-operatedfloat

Product overview
Hydraulically operated control valve that controls reservoir filling and reservoir level. Reservoir filling responds to a hydraulically controlled non-modulating bi-level vertical float that opens at a pre-set low level and shuts off drip-tight at a pre-set high level.
