5/3-way solenoid valve, pilot-operated, exhaust centre, G 1/4, 850 l/min, 230 V AC - E.MC

Double-acting cylinders and rotary actuators need two working ports and, depending on the job, a clearly defined rest position. The pilot-operated valve from the E.MC RV series switches with two 230 V AC coils and passes up to 850 l/min at its G 1/4 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 850 l/min at 4.8 mm nominal diameter and 18 mm² effective area (Cv 1.00), 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.

Applications

• Medium-size cylinders with higher air demand where the exhaust should also be led off in G 1/4.
• Actuators that must be free of force while the machine is stopped, for example during maintenance.
• Simple controls that run directly on 230 V AC without a power supply.

Accessories and spare parts

A matching 230 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.
