5/3-way solenoid valve, pilot-operated, closed centre, G 1/4, 600 l/min, 24 V DC - E.MC

When a cylinder has to do more than reach its two end positions, stopping or being released along the way, a 5/3-way valve is the right choice. The pilot-operated valve from the E.MC RV series switches with two 24 V DC 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

• 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.
• Service life of at least 40 million switching cycles, roughly 11,000 operating hours at one cycle per second.
• Operating pressure of 1.5 to 8 bar with a 12 bar test pressure, and the air does not need to be lubricated.
• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.

Applications

• Medium-size cylinders in fixtures and feeders, piped in G 1/4.
• Stopping lift cylinders and swivel arms at intermediate positions, for example when positioning workpieces.
• Direct control from PLC outputs at 24 V DC.

Accessories and spare parts

A matching 24 V DC 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.
