3/2-way solenoid valve, normally open (NO), G 1/8, 590 l/min, 12 V DC, 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. At 12 V DC it runs on vehicle electrical systems and battery-powered equipment. 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.
• Only 2.5 W power consumption per coil, coil without polarity and insulation class F.
• 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.

Applications

• Spring-applied brakes and holding cylinders that are vented only briefly to release.
• Sealing and purge air that should keep flowing when power fails.
• Vehicle bodies and mobile equipment with a 12 V supply.

Accessories and spare parts

The replacement solenoid coil, type L for 12 V DC, 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.
