5/3-way solenoid valve, pilot-operated, pressure centre, G 1/4, 600 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 600 l/min at its G 1/4 port. With neither coil energised, the spool sits in the centre position. Both working ports are then supplied with pressure. With a through rod the forces balance out, with a single rod the area difference pushes the piston slowly outwards.

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.
• 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.
• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.

Applications

• Simple controls that run directly on 230 V AC without a power supply.
• Gentle follow-up stroke of a single-rod cylinder driven by the area difference.
• Medium-size cylinders in fixtures and feeders, piped in G 1/4.

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.
