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 S4V and S4M series?

S4V is a standard inline 5/2 way solenoid valve with threaded ports for general piping connection. S4M is a NAMUR standard solenoid valve designed for direct mounting on pneumatic actuators without additional tubing. Choose S4V for standard pneumatic circuits; choose S4M for valve automation applications.

Q:What is the advantage of stainless steel material?

Stainless steel offers excellent corrosion resistance, making S4V/S4M series ideal for harsh environments including chemical plants, food processing, pharmaceutical manufacturing, marine applications, and outdoor installations where standard aluminum valves would corrode.

Q:What is the operating pressure range of S4V series?

Operating pressure range is 0.15-0.8 MPa (1.5-8 bar, 21-114 psi) with maximum proof pressure of 1.2 MPa (175 psi).

Q:What is the difference between single coil and double coil models?

Single coil models (4E1, e.g. S4V210-08) feature spring return - the valve returns to its home position when power is removed. Double coil models (4E2, e.g. S4V220-08) feature bistable memory function - the valve maintains its last position after power removal until an opposing signal is applied.

Q:Does the S4V series require lubrication?

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