3/2-way solenoid valve, normally open (NO), G 1/8, 590 l/min, 230 V AC, standard connector - YPC SF2701

The SF2701 works the other way round from a normally closed valve. In its home position it is open and supplies the consumer with compressed air. When the solenoid is energised, it blocks the pressure port and vents the working line. 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

• De-energised, the passage is open, so the consumer stays supplied with pressure on power loss.
• 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

• Sealing and purge air that should keep flowing when power fails.
• Clamping units that stay closed at rest and open only to change the workpiece.
• 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. A matching manifold is available for 3-way valves of the SF2000 series.
