Product Information
Full details
This Heschen 4V210-08 electrical pneumatic solenoid valve is designed for industrial automation and control systems. It offers reliable 5-way, 2-position directional control with quick-fit pneumatic connections, ideal for managing air flow in automated processes. A potential consideration is its specific DC 24V operating voltage, requiring a compatible power supply.

Extended Product Information
FAQs
What is the operating voltage for this solenoid valve?
The Heschen 4V210-08 operates on a DC 24V coil voltage.
What does '5/2 Way' mean?
It signifies a 5-port, 2-position valve. It has five ports (pressure, two work ports, two exhaust) and two distinct states or positions for controlling air flow.
What size tubing fits the quick fittings?
The inlet/outlet ports use quick fittings for 6mm inner diameter tubing, and the base fittings use 8mm inner diameter tubing.
Can this valve be used with AC power?
No, this specific model (4V210-08) is designed exclusively for DC 24V operation. Using AC power will damage the coil.
How do I connect the electrical wires to the coil?
The valve typically has electrical terminals or flying leads. Connect the positive (+) and negative (-) wires from your DC 24V power supply to the appropriate terminals on the solenoid coil. Refer to the valve's specific wiring diagram for precise instructions.
Is lubrication required for the compressed air?
This valve can operate with clean, dry air or lubricated air. If using lubricated air, ensure the lubricant is compatible with valve seals.
What is the purpose of the muffler on the exhaust ports?
The muffler is designed to reduce the noise generated by exhausted air escaping from the valve.
Troubleshooting
Valve does not actuate when energized
Verify DC 24V power supply is connected correctly to the coil and providing the correct voltage. Check for loose wiring or open circuits. Ensure the pilot signal is sufficient if it's a pilot-operated valve.
Slow or incomplete cylinder stroke
Check for air leaks in the connected tubing or cylinder. Ensure the air supply pressure is adequate. Clean or replace any clogged mufflers or exhaust ports.
Valve leaks air from exhaust ports
Ensure the valve is correctly shifted by the pilot signal. Check for debris trapped in the valve seat. If leakage persists, the internal seals may be worn, and the valve may need replacement.
Quick fitting will not secure tubing
Ensure the tubing is cut cleanly and squarely. Check for damage to the end of the tubing. Verify the correct tubing outer diameter is being used.
Pros and Cons
Pros
- Reliable internal piloting for consistent performance.
- Standard PT1/4 port size for broad compatibility.
- Quick fittings simplify and speed up pneumatic connections.
- Suitable for DC 24V control systems commonly found in automation.
- Manifold base design supports space-saving arrangements.
Cons
- Limited to DC 24V operation; AC or other voltage systems require different models.
- Specific fitting sizes (6mm inlet/outlet, 8mm base) may require adapters if not standard for your setup.
- Net weight of 1567g makes it a substantial component, consider mounting and vibration.
- As an internally piloted valve, it requires a pilot signal to shift positions.
Setup, Compatibility & Care
Setup:
- Identify Port Functions: Refer to the valve markings (e.g., P for pressure, A/B for outlets, R/S for exhaust) to correctly connect pneumatic lines.
- Connect Pneumatic Lines: Use the provided quick fittings. For inlet/outlet ports, ensure 6mm inner diameter tubing is firmly seated. For base fittings, use 8mm inner diameter tubing.
- Electrical Connections: Connect the DC 24V coil wiring. Ensure correct polarity if applicable (consult valve documentation or markings).
- Mounting: Secure the valve to a manifold base or a suitable mounting surface using appropriate fasteners. Ensure the valve is oriented correctly for air flow.
Compatibility:
- Voltage: Requires a stable DC 24V power source.
- Air Supply: The valve is designed for clean, dry, or lubricated compressed air. Ensure the air pressure is within the valve's operating range.
- Tubing: Compatible with standard pneumatic tubing sizes (6mm OD for A/B/R/S, 8mm OD for base exhaust if applicable).
Care:
- Regularly inspect pneumatic connections for leaks.
- Ensure the air supply is filtered and free from excessive moisture or contaminants to prevent internal damage.
- Keep the valve exterior clean using a dry or slightly damp cloth. Avoid harsh solvents.
