5/3-way solenoid valve, pilot-operated, closed centre, G 1/8, 450 l/min, 12 V DC - 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 12 V DC 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. All ports are then blocked, so the cylinder stops where the signal drops out, with air trapped in both chambers.

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.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 2.8 W.
• Operating pressure of 1.5 to 8 bar with a 12 bar test pressure, and the air does not need to be lubricated.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.
• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.

Applications

• Mobile equipment and battery-powered systems running on 12 V DC.
• Stopping lift cylinders and swivel arms at intermediate positions, for example when positioning workpieces.
• Compact handling assemblies with short tubing runs and small cylinders on G 1/8 ports.

Accessories and spare parts

A matching 12 V DC 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.
