Key features

Locks the cylinder position automatically when power is cut off, ideal for safety-critical applications requiring emergency stop and anti-fall protection to prevent unintended equipment movement.

The spool remains in its position after the single-side coil is energized, eliminating the need for continuous power supply and reducing energy consumption and coil overheating risks.

The precision-machined inner bore minimizes friction, requiring low start-up pressure. The oil-free lubrication design reduces maintenance costs and delivers a service life exceeding industry averages

AI-Powered supplier vetting

SummaryThe supplier demonstrates established customization and R&D capabilities, including sample-, design-, minor-, full-, and flexible-customization services, ODM availability, recent new-product development, and eight utility model patents. Production-related evidence includes CNC and assembly equipment, an automated solenoid-valve testing system, documented finished-product inspection instructions, and two quality inspectors. The supplier holds ISO9001:2015 and CCC certifications and reports OEM service for well-known brands. Service management procedures for supplier capability, corrective and preventive actions, and customer complaints are documented and followed. However, overseas service infrastructure is limited: there are no overseas warehouses, showrooms, agents, or branches, and the stated number of countries served overseas is zero. Financial records are referenced for multiple years, but the provided slices do not establish financial strength or credibility. Customer-specific cases are not identified.

Supplier typeThe supplier is presented as an R&D-oriented manufacturer offering ODM services, OEM services for well-known brands, and pneumatic technology expertise. Its stated capabilities include both standard-product modification and fully customized technical solutions.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CCC product compliance certification. These explicitly support quality-management and product-compliance credentials.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints and corrective/preventive actions. However, it has no overseas warehouse, showroom, agent, or branch, and reports service coverage in zero countries, limiting evidenced overseas after-sales infrastructure.

R&D capabilityThe supplier reports new products within the past year, an R&D team focused on pneumatic technology, an available SDK, one national science and technology progress award, and eight utility model patents. These are explicit indicators of active innovation and technical development.

Production capacityThe supplier lists assembly, CNC lathe, CNC machining center, drilling, laser marking, and automated solenoid-valve testing equipment. It also reports uniformly followed finished-product inspection instructions and one-month peak and off-peak lead times, supporting an established production process.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, supported by a professional R&D team and tailored technical design assistance. ODM service is also available.

Product Q&A

Q:What does "Type C" neutral function mean for this valve?

"C" stands for closed-center. When the valve is in the neutral position (power off), the inlet port (P), two working ports (A/B), and exhaust ports (R/S) are all blocked. Air inside the cylinder cannot escape, keeping the piston locked in its current position, which is widely used for safety-locking applications.

Q:Why do the coils keep burning out?

Spool stuck: Impurities in compressed air prevent the spool from returning, causing the coil to stay energized and overheat. Install an air filter and clean the valve body regularly. Unstable voltage: Voltage fluctuations exceeding 10 can overload the coil. A voltage stabilizer is recommended. High ambient temperature: Operating temperatures above 50C accelerate insulation aging. Improve heat dissipation or select a high-temperature coil version.

Q:The cylinder does not move after powering on the solenoid valve. How to troubleshoot?

Check if the power wiring is loose and if the voltage matches the coil specification (e.g., a DC24V coil connected to AC220V will be damaged immediately). Use the manual override button to test if the spool can be pushed. If not, the spool is likely stuck by debris and needs cleaning or replacement. Verify that the air supply pressure meets the minimum working pressure of 0.15 MPa. Insufficient pressure cannot drive the spool to shift.

Q:Is lubrication required during operation?

No additional lubrication is needed. The valve is factory-prelubricated with high-performance grease, and its low-friction design supports oil-free operation. In fact, oil mist from the air supply may cause carbon buildup and spool sticking. Keep the air source clean and dry for best performance.

Q:Can this valve directly replace an AirTAC 4V430C-15?

Yes. It features universal installation dimensions and port specifications, allowing direct replacement of equivalent AirTAC models without modifying piping or mounting holes.
