3/2-way valve bistable, electropneumatic, series 70 low temperature to -40 °C, G 1/8, 230 V AC, type 517.TT.32.18.B.230A - Riegler 150031

On valve 517.TT.32.18.B.230A an electrical signal gives the command, which is executed by a pneumatic pilot stage. Switching behaviour: the valve is bistable and keeps the last switched position until the opposite signal arrives. Valve 517.TT.32.18.B.230A 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 517.TT.32.18.B.230A operates up to 10 bar, minimum 3 bar at -10 to 60 °C and 5 bar at -40 to -10 °C.
• Medium temperature -40 to 60 °C, ambient -40 to 50 °C.
• Latching manual override.
• On valve 517.TT.32.18.B.230A: aluminium valve body, nickel-plated aluminium piston, special steel spring.

Applications

Typical tasks are single-acting cylinders, blow-off air and piloting downstream valves. The 517.TT.32.18.B.230A 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 517.TT.32.18.B.230A is built for medium and ambient temperatures down to -40 °C, such as cold stores or outdoor installations.
