ccessories Differential by-pass 596 Differential by-pass for 65, 66 and 67 series units. Max. working pressure: bar. Max. working temperature:. Setting range: kpa (, m w.g.). Connections M x M. Installation of the differential by-pass valve To fit the differential by-pass, it should be applied in place of the by-pass spacer template. fter shutting off the ball valves using the specific supplied spanner, unscrew the captive nuts as illustrated in the following figures. The differential by-pass valve is used to control the head to which the secondary distribution circuit is subjected. When the differential pressure setting value is reached, the obturator opens and allows the medium to pass from the flow to the return line of the circuit, limiting the differential pressure at the set value. This action is particularly useful when single circuits are shut off by automatic two-way ON/OFF, modulating or thermostatic valves.

The hydraulic characteristics are calculated while taking account of the ball shut-off valves fitted.
