Pressure sustaining valve and level control VH512

Product description

Basic valve, 2W stainless steel support pilot, stainless steel needle valve, 2/3W double level float pilot, pressure gauge.

Operation

The valve guarantees that despite the drop in the level of the tank, the valve will not open fully, but will maintain a moderate pressure drop and flow velocity in the network in order to avoid damage to the valve, high pressure fluctuations in the net and possible water hammer on the closure. This scheme is also applicable to the modula- ting float valve, although as it is a progressive closure, it is not usually necessary.
