5/3-way solenoid valve, pilot-operated, pressure centre, G 1/2, 1350 l/min, 12 V DC - 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 12 V DC coils and passes up to 1350 l/min at its G 1/2 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

• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.
• Flow rate of 1350 l/min at 6.2 mm nominal diameter and 30 mm² effective area (Cv 1.67), enough air for brisk strokes without the valve throttling them.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.
• Service life of at least 40 million switching cycles, roughly 11,000 operating hours at one cycle per second.

Applications

• Mobile equipment and battery-powered systems running on 12 V DC.
• Gentle follow-up stroke of a single-rod cylinder driven by the area difference.
• Large-volume cylinders and rotary actuators that need 1350 l/min at a G 1/2 port.

Accessories and spare parts

A matching 12 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.
