3/2-way valve bistable, electropneumatic, series 70 low temperature to -40 °C, G 1/8, without coil, type 70L1020100 - Riegler 149936

The 3/2-way valve bistable 70L1020100 switches on an electrical signal, the actual changeover is performed by a pneumatic pilot stage. Switching behaviour: the valve is bistable and keeps the last switched position until the opposite signal arrives. Valve 70L1020100 has port G 1/8 female thread and nominal size DN 5 mm, flow 550 Nl/min at 6 bar and Δp 1 bar.

Benefits

• At 6 bar the valve passes 550 Nl/min with Δp 1 bar and 400 Nl/min with Δp 0.5 bar.
• Valve 70L1020100 operates up to 10 bar, minimum 3 bar at -10 to 60 °C and 5 bar at -40 to -10 °C.
• Medium -40 to 60 °C, ambient -40 to 60 °C.
• Latching manual override for switching without a signal.

The valve is used for single-acting cylinders, blow-off air and piloting downstream valves. The 70L1020100 can be installed in-line, mounted directly on the cylinder with a special adapter or used as a series valve on multi-base plates and supply strips. The low temperature version 70L1020100 is built for medium and ambient temperatures down to -40 °C, such as cold stores or outdoor installations.
