What is the seal material and temperature range?

Standard NBR seal for -5~80. FKM fluororubber is optional for high temperature applications.

What is the valve status when power off?

Standard version is normally closed: closed when power off, open when energized. Normally open type can be customized.

Is the valve easy to get stuck if the medium contains tiny impurities?

Direct acting structure is more resistant to fine impurities than pilot valves. Filter is recommended for better service life.

Can it be equipped with explosion-proof coil or timer?

Yes, explosion-proof coil and timer are available as custom options.

What equipment is PU220 commonly used on?

Widely used in pneumatic automation equipment, car washers, water supply systems, air compressors and light oil automatic control.

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 structure is PU220 solenoid valve and which media is applicable?

PU220 series is 2/2 way direct acting solenoid valve, normally closed as standard, suitable for neutral media such as compressed air, clean water and light oil.
