5/3-way solenoid valve, pilot-operated, exhaust centre, G 1/8, 450 l/min, 24 V AC - E.MC

When an actuator has to stop in a defined way rather than just extend and retract, it needs a third switching position. The pilot-operated valve from the E.MC RV series switches with two 24 V AC coils and passes up to 450 l/min at its G 1/8 port. With neither coil energised, the spool sits in the centre position. Both working ports are then open to exhaust. The actuator is depressurised and can be pushed by hand.

Advantages

• Flow rate of 450 l/min at 3.4 mm nominal diameter and 9 mm² effective area (Cv 0.50), enough air for brisk strokes without the valve throttling them.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.
• Service life of at least 40 million switching cycles, roughly 11,000 operating hours at one cycle per second.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 3 VA.
• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.

Applications

• Compact handling assemblies with short tubing runs and small cylinders on G 1/8 ports.
• Setting up and adjusting fixtures where the cylinder has to be moved by hand at rest.
• Control circuits fed by a control transformer at 24 V AC.

Accessories and spare parts

A matching 24 V AC replacement coil, type S, is available separately. For wiring with plug-in connectors, E.MC lists connection cables in 0.3, 0.6 and 1 m lengths.
