5/3-way valve centre exhausted, electropneumatic, series 70, G 1/2, 230 V AC, external pilot air, type 517.53.12.E.OC.230A - Riegler 147330

The 5/3-way valve centre exhausted 517.53.12.E.OC.230A switches on an electrical signal, the actual changeover is performed by a pneumatic pilot stage. Switching behaviour of valve 517.53.12.E.OC.230A: in the mid position both working ports are exhausted and the actuator is depressurised. Valve 517.53.12.E.OC.230A has port G 1/2 female thread and nominal size DN 15 mm, flow 4600 Nl/min at 6 bar and Δp 1 bar.

Benefits

• Flow 4600 Nl/min (Δp 1 bar) or 3200 Nl/min (Δp 0.5 bar) at 6 bar.
• Operating pressure -0.99 to 10 bar: thanks to external pilot air at 2.5 to 10 bar the G 1/2 valve also switches vacuum.
• Medium temperature -10 to 60 °C, ambient -10 to 50 °C.
• Latching manual override.
• Connector and coil 230 V AC, 50/60 Hz are included.

Applications

Typical tasks are actuators that must be depressurised and movable by hand in the mid position. The valve with G 1/2 fits in-line, directly on the cylinder via special adapter, or as a series valve on multi-base plates and supply strips.
