Technical characteristics • These valves have two inlets and one output connection and are normally called low pressure selector valves as, when receiving two separate pressure supply, only allow the passage of the lowest pressure. The most common application is to operate a component from two separate positions. • On DIN rail using the relevant adaptor kit (see accessories). • With 90° bracket (see accessories). • Directly on the support plate thanks to two through holes on the body. Technical characteristics • Fluid: Filtered and lubricated air or non • Working ports size: see connections list • Max working pressure: 10 bar • Temperature: -5 °C ... + 50 °C • Weight: 10 g • Flow rate at 6 bar with Δp=1 (Nl/min): 550 Nl/min Pneumatic symbols Note Example: 551.151.D6.D6.D6 Circuit selector valve AND.

Their function is to discharge the air directly into the atmosphere without going through the pneumatic circuit enabling the actuator to reach the maximum speed. • On DIN rail using the relevant adaptor kit (see accessories). • With 90° bracket (see accessories). • Directly on the support plate thanks to two through holes on the body.
