5/3-way solenoid valve, pilot-operated, closed centre, G 1/4, 850 l/min, 24 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 24 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. All ports are then blocked, so the cylinder stops where the signal drops out, with air trapped in both chambers.

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.
• Operating pressure of 1.5 to 8 bar with a 12 bar test pressure, and the air does not need to be lubricated.
• 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

• Medium-size cylinders with higher air demand where the exhaust should also be led off in G 1/4.
• Holding the piston position when both control signals drop out at the same time.
• 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.
