4. Setup and Installation
Proper installation is crucial for the valve's performance and longevity. This valve is designed for mounting on a sub-base.
4.1 Mounting
- Ensure the mounting surface is clean and flat.
- Mount the valve securely onto the designated sub-base. The maximum tightening torque for valve mounting is 2 Nm.
- The valve can be mounted in any position.
4.2 Pneumatic Connections
- Connect pneumatic lines to the G1/4 ports on the sub-base, ensuring all connections are tight and leak-free.
- The pneumatic working port is G1/4, compatible with sub-bases of size 26 mm as per ISO 15407-1 and Size 01 as per VDMA 24563.
- Auxiliary pilot air ports 12 and 14 are also sub-base, size 26 mm as per ISO 15407-1.
- Pilot exhaust air ports 82/84 can be ducted or not ducted as per standard.
4.3 Electrical Connections
- Connect the electrical supply to the solenoid coils. The electrical connection is Form C as per DIN EN 175301-803, without PE conductor.
- The operating voltage is 24V AC.
- Ensure the power supply matches the valve's specifications (24 V AC: 50/60 Hz, initial power 3.1 VA, holding power 2.3 VA).
- Permissible voltage fluctuations are -15% / +10%.
5. Operating Instructions
The VSVA-B-T32U-AZH-A1-1AC1 is a 2x3/2, open, monostable, pilot-controlled valve with electrical actuation.
- Actuation: The valve is actuated electrically. Applying the specified voltage to the solenoid coil will shift the valve position.
- Reset Method: The valve resets via a pneumatic spring when the electrical signal is removed.
- Manual Override: A non-detenting manual override is available for testing or emergency situations.
- Signal Status Display: An LED indicator provides visual confirmation of the valve's signal status.
- Operating Medium: Use compressed air as per ISO 8573-1:2010 [7:4:4]. Operation with oil lubrication is possible (required for further use).
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of the valve.
- Inspection: Periodically inspect the valve and connections for leaks, damage, or wear.
- Cleaning: Keep the valve and surrounding area clean. Avoid using harsh chemicals that could damage the housing or seals.
- Air Quality: Ensure the compressed air supply meets the specified quality standards to prevent internal contamination.
- Replacement: If any part of the valve is damaged or worn, replace it with genuine FESTO spare parts.
7. Troubleshooting
Refer to the table below for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not switch | No electrical signal; Incorrect voltage; Low pilot pressure; Contamination | Check electrical connections and power supply; Verify pilot pressure (3-10 bar); Check air quality and clean if necessary. |
| Air leakage | Loose pneumatic connections; Damaged seals | Tighten connections; Inspect and replace seals if damaged. |
| Slow response | Low operating pressure; Contamination; Incorrect pilot air supply | Verify operating pressure (2-10 bar); Check air quality; Ensure pilot air supply is external and correct. |
