3/2-way solenoid valve, normally open (NO), G 1/4, 980 l/min, 230 V AC - 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. The 230 V AC coil (4.1 VA) runs directly on mains voltage without an extra power supply. This pilot-operated spool valve from the SF4000 series moves 980 l/min through its G 1/4 ports.

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.
• 980 l/min flow on a 26 mm wide body, easy to mount side by side.
• 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

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

Accessories and spare parts

A matching 230 V AC replacement coil is available separately. For manifold mounting, YPC offers the MF4300 manifold base for 3-way valves in the SF4000 series.
