More Information

Overview Manuals Valve Matching Installation Pneumatic Diagnosis Product Applications

Features:

  • Bistable directional control: Separate solenoids command both spool positions and preserve the last selected path.
  • Standardized valve interface: ISO 15407-1 geometry supports documented manifold integration.
  • Industrial enclosure protection: The electrical arrangement is rated for demanding environments when correctly assembled.
VSVA-B-B52-ZD-A1-1T1L controls both directions of a pneumatic actuator from a two-coil 5/2 spool arrangement.

Its negative-to-positive working-pressure range supports defined vacuum and pressure service only when the complete valve terminal is configured accordingly.

Replacement acceptance confirms mechanical interface, connector keying, coil voltage, flow capacity and the machine response to retained spool position.

Apter Power can help confirm the Festo VSVA-B-B52-ZD-A1-1T1L 5/2-way Double-solenoid Valve, manifold interface, voltage, function and connector arrangement before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Spool function: Require the same 5/2 double-solenoid behavior unless the control and safety design is revised.
  • Interface: Compare the ISO valve footprint, manifold station and porting arrangement.
  • Electrical code: Match 24 VDC coils and the documented connector/keying combination.
  • Flow demand: Confirm actuator speed and exhaust capacity against the published nominal flow.
  • Energy isolation: Exhaust both actuator chambers and secure external loads before removing the valve.
  • Seal condition: Keep manifold seals clean, correctly seated and compatible with the medium.
  • Fastening: Tighten mounting hardware evenly to the prescribed torque.
  • Connector sealing: Assemble plugs and gaskets so the stated enclosure rating is maintained.
  • No movement: Separate supply, coil, connector, spool and actuator faults before replacement.
  • One-way failure: Compare both coil commands and both exhaust paths because each direction is independently actuated.
  • Unexpected retention: Treat the last spool position as energized machine state until pressure is removed.
  • Leak check: Inspect seals, tubing and manifold surfaces before condemning the valve body.
  • Double-acting cylinders: Commands extend and retract flow paths from a valve manifold.
  • Machine clamping: Controls two-direction pneumatic fixtures where retained state is addressed safely.
  • Process skids: Provides standardized directional control in documented valve-terminal assemblies.
  • Legacy station repair: Restores a matching VSVA valve without redesigning the manifold interface.
Description
VSVA-B-B52-ZD-A1-1T1L is an electrically actuated 5/2-way valve with two solenoids, directing compressed air for a double-acting actuator through an ISO 15407-1 interface.

The bistable spool behavior of VSVA-B-B52-ZD-A1-1T1L means the last commanded flow path can remain when neither coil is energized. Machine isolation must therefore address retained pneumatic energy as well as electrical power.

VSVA-B-B52-ZD-A1-1T1L combines 24 VDC actuation, a 26 mm valve width, G1/4 connection data and the documented connector arrangement. All of those elements require comparison before a manifold replacement is released.

Technical notes
VSVA-B-B52-ZD-A1-1T1L is a bistable double-solenoid valve, so removing coil power does not guarantee a safe spool position. Isolate electricity and compressed air, exhaust retained pressure, secure the actuator load, and verify manual-override state before service. Stop installation if the interface, keying, voltage, flow direction or pneumatic function differs.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can a single-solenoid valve be fitted in place of VSVA-B-B52-ZD-A1-1T1L during a repair?
Not as an equivalent change. A spring-return valve changes the de-energized machine response, so the pneumatic circuit, PLC sequence and risk assessment would need redesign approval.
How should an engineer confirm that VSVA-B-B52-ZD-A1-1T1L matches an existing manifold station?
Require the documented ISO interface and compare the station porting, fastening and connector keying. Stop if the manifold cannot accept the exact valve arrangement without modification.
Why might one actuator direction fail after installing VSVA-B-B52-ZD-A1-1T1L?
Each direction has its own electrical command and pneumatic path. Compare the two coil commands and exhaust paths to isolate a control, connector, spool or circuit fault.
What must be preserved when replacing VSVA-B-B52-ZD-A1-1T1L on a working valve terminal?
Keep the approved station assignment, connector orientation and control sequence. Recommission the affected actuator before returning the manifold to automatic operation.
When should receiving staff reject VSVA-B-B52-ZD-A1-1T1L?
Reject the item if the complete Festo model and part number 539156 cannot be tied to the delivered valve or if the connector and valve function differ.
How should a technician prove VSVA-B-B52-ZD-A1-1T1L after a leak repair?
Restore pressure under controlled conditions, command both directions and confirm the actuator holds as designed. If leakage continues, separate the manifold seal, tubing and valve-body paths.
