5/3-way solenoid valve, pilot-operated, closed centre, G 1/4, 600 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 600 l/min at its G 1/4 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

• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.
• Flow rate of 600 l/min at 3.9 mm nominal diameter and 12 mm² effective area (Cv 0.67), enough air for brisk strokes without the valve throttling them.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 4 VA.
• Service life of at least 40 million switching cycles, roughly 11,000 operating hours at one cycle per second.

Applications

• Stopping lift cylinders and swivel arms at intermediate positions, for example when positioning workpieces.
• Medium-size cylinders in fixtures and feeders, piped in G 1/4.
• Control circuits fed by a control transformer at 24 V AC.

Accessories and spare parts

A matching 24 V AC replacement coil, type T1, is available separately. For wiring with plug-in connectors, E.MC lists connection cables in 0.3, 0.6 and 1 m lengths.
