Spool Structure

Advantage: Provides excellent sealing performance, effectively reducing air leakage to improve system energy efficiency. It also offers a fast response, ensuring precise and synchronized equipment operation.
Application: Ideal for automated production lines that require high-speed response and precision, such as in packaging, sorting, and assembly equipment.

Manual Override Device

Advantage: Simplifies the installation and commissioning process. On-site engineers can test the valve's operation without power, significantly boosting work efficiency.

Multiple Thread Options

Advantage: Provides various options like G threads and NPT threads, allowing you to select the appropriate type based on regional and equipment standards.

To ensure optimal performance and service life, please follow these key installation points:

Air Source Requirement: Use clean air filtered by 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: The coil for the DC 24V specification has polarity requirements for the indicator light terminals. Connect "1" to the positive pole and "2" to the negative pole.

Problem	Possible Cause	Solution
Valve doesn't 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 and remove any blockages.
Excessive leakage	1. Valve spool or seal is worn. 2. Foreign matter is inside the valve body.	1. Replace the worn or aged components. 2. Clean the inside of the valve body.
Sluggish action	1. Clearance between valve spool and sleeve has increased. 2. Impurities or deposits are inside.	1. Check and adjust the clearance. 2. Clean the inside of the valve.

Efficient and Reliable, with Fast Response: An effective orifice of 17.0mm² and a Cv value of 1.0 ensure a fast response and precise, synchronized movements in your pneumatic system.
Oil-Free and Low Maintenance: The spool structure provides excellent sealing without the need for additional lubrication, significantly reducing daily maintenance tasks and costs while extending equipment uptime.
Flexible Installation and Wide Application: The DC 24V is a common safe voltage in automation equipment, offering great compatibility. It can be integrated with a dedicated manifold to form a compact valve group, saving valuable installation space.
High-Value Industrial Solution: The Airtac brand is known for providing stable, durable, and reliable pneumatic components at a great price point.

Manifold/Base: It is recommended to use the 4V200 series manifold to simplify piping layout and save installation space.
Air Preparation Unit: Pair it with an Airtac FRL series (Filter, Regulator, Lubricator), especially the filter with a 40μm element, to ensure air cleanliness.
Silencer and Fittings: Install a silencer on the exhaust port for dust prevention and use quick-connect fittings suitable for the 1/4" and 1/8" ports for easy installation.
