3/2-way solenoid valve, normally closed (NC), G 1/8, 590 l/min, 24 V DC, LED connector - YPC SF2601

The SF2601 is a 3/2-way valve that is closed in its home position. Without a signal the pressure port is blocked and the working port vents to exhaust. Only when the solenoid is energised does air flow to the consumer. At 5 bar up to 590 l/min pass through the G 1/8 ports. The 24 V DC coil can be driven directly from a PLC output.

Advantages

• De-energised, the pressure port is blocked, so a power failure vents the consumer.
• Switching time of 25 ms max. at 5 bar and up to 5 Hz switching frequency for short machine cycles.
• 18 mm body width and a 15 mm coil, so several valves can sit close together.
• Oil-free operation, no lubrication required. If the air is oiled, use ISO VG32.
• An LED in the connector shows the switching state at the valve, and the suppressor damps the coil turn-off voltage.

Applications

• Single-acting spring-return cylinders that extend only while the signal is active.
• Blow-off air and nozzles that are switched on for short periods.
• Systems with many valves, where the LED makes troubleshooting possible without a meter.

Accessories and spare parts

The replacement solenoid coil, type L for 24 V DC with 2 W, is available separately and can be changed without opening the pneumatic circuit. A matching manifold is available for 3-way valves of the SF2000 series.
