5/3-way solenoid valve, pilot-operated, closed centre, G 1/2, 1350 l/min, 24 V AC - 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 AC 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. All ports are then blocked, so the cylinder stops where the signal drops out, with air trapped in both chambers.

Advantages

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

Applications

• Control circuits fed by a control transformer at 24 V AC.
• Stopping lift cylinders and swivel arms at intermediate positions, for example when positioning workpieces.
• Large-volume cylinders and rotary actuators that need 1350 l/min at a G 1/2 port.

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.
