5/3 solenoid valve for pneumatic control
The Festo VSVA-B-P53C-ZH-A1-1AC1 is a 24V AC solenoid valve designed for pneumatic automation systems. It uses a 5/3 closed-centre function with overlap lap to block flow in the neutral position. The valve suits machine builders and maintenance engineers who need reliable directional control in compressed-air circuits.
Pilot-operated with external pilot supply
Installation requires connecting the external pilot air port and wiring the 24V AC coil, which draws 3.1 VA initially and 2.3 VA holding. The non-detenting manual override allows momentary actuation without tools. A common issue is insufficient pilot pressure below 3 bar, which prevents reliable switching.
Flow capacity and pressure limits
The valve delivers a standard nominal flow of 1000 l/min and up to 1400 l/min on the valve body, with 1100 l/min on an individual sub-base. It operates from -0.9 bar vacuum to 16 bar pressure, while pilot pressure must stay between 3 and 10 bar. Duty cycle is 100 per cent for continuous operation.

Questions about this item
How do I confirm the VSVA-B-P53C-ZH-A1-1AC1 is switching correctly after installation?
Apply 24 V AC and watch the LED signal status display; the valve should change state within 23 ms on and 58 ms off, with a 35 ms changeover time.
What comes in the box and what must I supply separately?
The box contains one valve (part 547126) with LED display and non-detenting manual override; you must provide 24 V AC power, external pilot air at 3–10 bar, compressed air per ISO 8573-1:2010 [7:4:4], and suitable tubing for G1/4 ports.
Which voltage and flow variant of the VSVA series should I choose for a 24 V AC system needing about 1000 l/min?
Select the VSVA-B-P53C-ZH-A1-1AC1 (547126) — it is rated 24 V AC, 50/60 Hz, with a standard nominal flow of 1000 l/min and 16 bar maximum operating pressure.
