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 4V110 and 4V210?
A:
Port size and flow. 4V110 has G1/8 ports with Cv 0.56; 4V210 has G1/4 ports with Cv 1.0. Use 4V210 for larger cylinders.
Q:What does the letter C mean in 4V130C/230C/330C/430C?
A:
C indicates 5/3 way closed center (all ports blocked in center position). Other options: E (exhaust center), P (pressure center).
Q:Can 4V series valves operate without lubrication?
A:
Yes, the sliding spool design works without oil. If lubricated air was used before, continue using same oil to maintain seal life.
Q:What is the manual override type?
A:
Non-locking push button on single coil models; locking screw type (for maintenance) on double coil models.
Q:Are NPT threads available?
A:
Yes. Standard is G thread (BSPP). NPT, PT (BSPT) are available upon request.
