3/2-way valve series 70, electropneumatic, monostable, NC, external pilot air, G 1/2, 24 V DC, type 517.32.12.E.NC.24D - Riegler 147226

The 3/2-way valve series 70, normally closed (NC), supplies cylinders and actuators via its G 1/2 port with a flow rate of 4600 Nl/min at 6 bar and Δp 1 bar. Type 517.32.12.E.NC.24D is switched electrically at 24 V DC, coil and connector are included. Operating pressure -0.99 to 10 bar.

Benefits

• Flow rate 4600 Nl/min at 6 bar and Δp 1 bar, 3200 Nl/min at Δp 0.5 bar (DN 15 mm)
• External pilot air 2.5 to 10 bar, allowing an operating pressure of -0.99 to 10 bar
• Medium temperature -10 to 60 °C, ambient temperature -10 to 50 °C
• 24 V DC coil and plug connector included
• Manual override latching for commissioning and testing
• Compressed air quality to ISO 8573-1 class 4.7.3

Applications

The NC normal position keeps the outlet unpressurised until the valve is actuated. This suits single-acting cylinders and blow-off air that should only flow when required. Depending on the system, type 517.32.12.E.NC.24D is installed in the line as an in-line valve, mounted directly on the cylinder with an adapter or assembled in banks on base plates and supply strips of the series 70.
