Product Features & Applications

Spool Structure

Advantage: The spool provides superior sealing, which minimizes air leakage and boosts system energy efficiency. Its responsive design ensures precise and synchronized equipment movements.
Application: Ideal for automated production lines that demand high response speed and precision, such as in packaging, sorting, and assembly machinery.

Manual Override

Advantage: Simplifies the installation and debugging process. Technicians can test valve operation without power, significantly improving work efficiency.

Multiple Thread Options

Advantage: Offers various thread types like G and NPT, making it easy to select the right fit for different regional and equipment standards.

Installation & Operation Guide

For best performance and longevity, follow these installation guidelines:

Air Source: Use clean air that has been filtered with a 40μm filter element.
Port Identification: P is the inlet port, A/B are the working ports, and R/S are the exhaust ports.
Wiring: For DC 12V coils with an indicator light, there are polarity requirements. Connect "1" to the positive pole and "2" to the negative pole.

Common Troubleshooting

Problem	Possible Cause	Solution
Valve fails to actuate	1. Air source is off or pressure is too low. 2. Coil is not powered or there's a power supply failure. 3. Valve spool is stuck.	1. Check the air source and pressure. 2. Check the power supply, wiring, and voltage. 3. Clean the valve spool to remove any blockages.
Excessive leakage	1. Valve spool or seal is worn. 2. Foreign matter is inside the valve body.	1. Replace any worn or aged components. 2. Clean the inside of the valve body.
Sluggish action	1. Clearance between the valve spool and sleeve has increased. 2. Impurities or deposits are inside.	1. Inspect and adjust the clearance. 2. Clean the inside of the valve.
