3/2-way solenoid valve, normally open (NO), G 1/4, 980 l/min, 24 V DC - YPC SF4701

This 3/2-way valve is normally open. Without a control signal the working port is pressurised, and energising the coil shuts off the supply and vents the load. Through its G 1/4 ports this SF4000 series valve delivers 980 l/min on a body only 26 mm wide. At 24 V DC and 2.1 W, the coil can be switched straight from a PLC output.

Advantages

• Normally open, the load stays pressurised if the voltage fails, operating pressure 1.5 to 10 bar.
• IP65 with DIN connector, coil insulation class F.
• Non-polarised, removable coil with 2.1 W power consumption.
• Switching time max. 25 ms at 5 bar, up to 5 Hz switching frequency.
• Runs on non-lubricated air, use ISO VG32 oil if lubricated.

Applications

• Single-acting clamp cylinders that stay clamped on power loss.
• Purge air or base supply that is switched off only on demand.
• Venting a circuit on signal, for example before maintenance.

Accessories and spare parts

A matching 24 V DC replacement coil is available separately. For manifold mounting, YPC offers the MF4300 manifold base for 3-way valves in the SF4000 series.
