Applications
The VHS40-N04A-Z is ideal for:
Industrial Automation: Maintenance and safety control of pneumatic equipment.
Pneumatic Systems: Rapid release of residual pressure during equipment maintenance or cleaning.
Safety Control: Ensuring operational safety by preventing unintended activation.
Installation and Operation
Installation: Ensure the valve is installed in a vibration-free environment with no strong electromagnetic interference. Use 1/2-inch NPT threads for a secure connection, and align the handle direction with the airflow.
Operation: Press and rotate the handle to switch between supply and exhaust states. During maintenance, lock the valve in the exhaust position to prevent accidental operation.
Maintenance: Regularly inspect the knob and handle for tightness and clean the valve surface to prevent dust and debris from affecting operation.
Noise Considerations
The VHS40-N04A-Z is designed for low noise operation. To further reduce noise:
Optimize Installation Location: Place the valve away from operators.
Use Silencers: Install silencers at the exhaust port to reduce noise during air release.
Adjust Operating Pressure: Lower the operating pressure if possible.
Important Notes
Avoid Overpressure: Ensure operating pressure stays within the rated range (0.1 MPa to 1 MPa) to prevent damage.
Regular Inspections: Check the valve's seals and thread tightness periodically.
Locking Function: Always lock the valve during maintenance to prevent accidental activation.
Frequently Asked Questions
Does VHS40-N04A-Z support other thread types?
The valve comes with NPT threads. For other thread types (e.g., Rc or G), contact SMC for customization.
How to choose the right SMC VHS series model?
The VHS series offers various sizes and thread types. Select based on your system's pipe diameter and pressure requirements (e.g., VHS40 for 1/2-inch connections).
Does VHS40-N04A-Z support remote control?
This smc pressure relief valve is manually operated and does not support remote control. Consider other series for remote control needs.
What is the maintenance cycle for VHS40-N04A-Z?
It is recommended to perform routine inspections every 3-6 months.
Are spare parts available for VHS40-N04A-Z?
SMC offers a range of spare parts, including seals and knobs, available through official channels or authorized dealers.
Does it support flow rate adjustment?
This 3 port pneumatic valve is designed for residual pressure release and safety control and does not support flow rate adjustment.
How to use the locking function?
The locking function is a key safety feature. During maintenance, switch the valve to the exhaust position, insert a padlock, and lock the handle to prevent accidental operation.
Are other colors or materials available?
The valve's body is made of die-cast aluminum, and the knob/top cover is made of flame-retardant PBT. Standard colors are red or gray. For custom colors or materials, contact SMC's technical support.
What is the maximum flow rate of VHS40-N04A-Z?
The valve is designed for high flow capacity, with a maximum theoretical flow rate increase of up to 88%. The actual flow rate may vary based on system pressure and layout.
Does it support bidirectional operation?
This 3 port pneumatic valve is a single-acting three-port valve and does not support bidirectional operation.
Is there a restriction on the installation direction?
The installation direction is critical. The handle must be aligned with the airflow direction to ensure proper operation.
Does it support rapid exhaust?
While not specifically designed for rapid exhaust, the valve's efficient release of residual pressure meets most industrial needs. For faster exhaust, consider adding a rapid exhaust valve downstream.
What is the lifespan of VHS40-N04A-Z?
The lifespan depends on usage frequency, environment, and maintenance. Regular maintenance can significantly extend its life.
Does it support modular installation?
This valve is designed for standalone use but can be integrated into larger pneumatic systems via piping connections. For modular installations, consider other SMC series.
