5/2-way solenoid valve, single solenoid, spring return, G 1/8, 590 l/min, 24 V DC, LED connector - YPC SF2101

The SF2101 suits a double-acting cylinder that has to return to a fixed position when power drops out. One solenoid shifts the spool, and as soon as the signal is gone, air and spring push it back to the home position. 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

• Without a signal the home position is clearly defined, so after an emergency stop or power loss the actuator sits in a known position.
• 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

• Clamping cylinders that retract to the open position when the machine is switched off.
• Gates, diverters and flaps in conveying systems with a defined rest position.
• 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. Several valves can be combined on an SF2000 series manifold with 2 to 14 stations, with supply and exhaust ports in size 1/4.
