5/2-way solenoid valve, single solenoid, spring return, G 1/8, 590 l/min, 230 V AC, standard 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. With the 230 V coil the valve can be switched straight from mains voltage, with no separate power supply needed. At 5 bar up to 590 l/min pass through the G 1/8 ports.

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.
• 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.
• Coil without polarity, insulation class F, removable, drawing 4.5 VA at 230 V AC.
• Switching time of 25 ms max. at 5 bar and up to 5 Hz switching frequency for short machine cycles.

Applications

• Gates, diverters and flaps in conveying systems with a defined rest position.
• Lift and feed cylinders at assembly stations, driven by a single PLC output per axis.
• Single valves on equipment without a low-voltage supply, switched at mains voltage via relays or timers.

Accessories and spare parts

The replacement solenoid coil, type L for 230 V AC, 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.
