AI-Powered supplier vetting

SummaryWAALPC is a limited company and national high-tech enterprise specializing in pneumatic components, including air-source treatment products, solenoid valves, and pneumatic fittings. It integrates product development, design, production, sales, brand operation, and after-sales service, with stated export coverage exceeding 40 countries and regions. Evidence supports customization from samples, raw-material traceability, CE certification, 100% finished-product inspection, and stated peak- and off-season lead times within 15 workdays. However, service and complaint-handling procedures lack written records, quality-control staffing is limited to one inspector, and no usable SDK is available. Financial information is represented only by years rather than substantive financial metrics, so financial credibility cannot be assessed. Customer-specific cases are not provided.

Supplier typeWAALPC is identified as a national high-tech enterprise and limited company focused on researching, developing, and producing pneumatic components. Its stated product scope covers pneumatics, air-source treatment, solenoid valves, and pneumatic fittings, with integrated sales and after-sales operations.

CertificationsThe supplier is reported to hold CE product certification. This is explicit evidence of certification capability, although no broader certification portfolio is provided.

After-Sales capabilityWAALPC states that it provides after-sales service and overseas equipment installation, with service quotations accepted on FOB/CIF terms and service payment terms of LC/T/T. However, the service-capability procedure and complaint-handling procedure have no written records, and the corrective/preventive-action mechanism also lacks written records.

R&D capabilityThe company describes itself as a national high-tech enterprise with research, development, design, technical resources, advanced machinery, testing facilities, and a continuous innovation policy. However, no usable SDK is available, and the supplied information does not provide concrete innovation outputs or measurable R&D results.

Production capacityWAALPC reports advanced processing equipment, complete testing facilities, 100% finished-product inspection, raw-material traceability, and stated average lead times within 15 workdays in both peak and off-season periods. Its product range and export activity further support operational capability, although only one quality assurance/control inspector is reported.

Customization capabilityThe supplier explicitly states that it can customize products and provide professional solutions, and its design-service capability is identified as customization from samples. This directly supports the ability to adapt products to customer requirements.

Product Q&A

Q:What is the difference between WASL-260-4E1 and WASL-260-4E2?

WASL-260-4E1 is a 5/2 way single coil (spring return) valve - it returns to its home position when power is removed. WASL-260-4E2 is a 5/2 way double coil (bistable) valve - it maintains its last position after power is removed until an opposing signal is applied.

Q:What applications is the WASI series suitable for?

The WASI series is designed for controlling double acting pneumatic cylinders in industrial automation systems, including packaging machinery, assembly lines, textile equipment, material handling, and general pneumatic control applications.

Q:What is the operating pressure range for WASI series?

The operating pressure range is 0.15-0.8 MPa (1.5-8 bar, 21-116 psi). Maximum proof pressure is 1.2 MPa (174 psi).

Q:Does the WASI series require lubrication?

No, the sliding spool design operates without lubrication. If lubricated air was used previously, continue using the same oil to maintain seal life. Recommended lubricant is ISO VG32.

Q:What is the difference between WASI series and 4V series?

WASI series features an upgraded design with improved sealing performance and optimized flow characteristics. Both are 5 port directional control valves, but WASI offers enhanced durability and reliability for demanding applications.
