What is the permissible operating pressure?

The permissible operating pressure is 1600 kPa, with an absolute pressure limit for steam also at 1600 kPa abs.

How does the valve achieve energy saving?

The controller automatically adjusts primary valve water flow based on secondary side outlet temperature, compensating for outdoor temperature changes to optimize comfort and reduce costs.

AI-Powered supplier vetting

SummaryThe supplier is associated with machinery, equipment, metal products, valves, and related industrial sales and services. It demonstrates broad customization capability, 100% finished-product inspection, OEM service for well-known brands, participation in the China Import and Export Fair, and a stated presence across several industrial sectors. However, raw-material traceability is absent, no SDK is available, and service-capability processes for supplier assessment, corrective actions, and complaint handling are undocumented. Production information indicates one production line and one year of R&D engineer experience, while environmental assessment and fire-drill status are unknown. Financial records are referenced for 2021–2023, but the provided slices do not establish financial strength.

Supplier typeThe supplier operates in industrial machinery and equipment, metal products, installation, repair, and valve manufacturing. Its stated business scope also includes construction-related, office, electronic, and import/export activities, indicating a diversified industrial trading and manufacturing profile.

CertificationsThe supplier is reported to hold one national science and technology progress award. No other certification, qualification, or formal management-system certification is identified in the provided information.

After-Sales capabilityThe supplier reports 98 qualified service-capability suppliers and has participated in an offline trade show, but it has no written procedures or records for service assessment, corrective and preventive actions, or effective complaint handling. It also lacks overseas warehouses, showrooms, agents, and branches.

Production capacityThe supplier manufactures self-operated pressure-regulating and process-control valves, operates one production line, and applies 100% finished-product inspection. Quality staffing is reported as 11–20 in one slice, while another lists one quality assurance and quality control inspector, creating inconsistent staffing evidence.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This directly indicates broad adaptation capability for customer-specific requirements.

Product Q&A

Q:What types of media can this valve handle?

It is suitable for cooling water, chilled water, low and high-temperature water, brine, heat transfer oils, saturated steam, and superheated steam.

Q:What is the leakage rate of the valve?

The leakage rate is extremely low, ranging from 0 to 0.01% of the kvs value, ensuring tight sealing.

Q:Can the valve be used for steam flow control?

Yes, but for steam control, it generally refers to 98% dryness saturated steam. For superheated steam, recalculation is necessary due to changes in fluid viscosity.

Q:What are the installation precautions for the actuator?

The actuator should be installed on the upper part of the valve body to prevent water leakage damage. Avoid installing at the 'U' bottom of the pipeline to prevent steam hammer.

Q:Does the valve support manual operation during power failure?

Yes, most models can be operated manually when power is cut off, ensuring continued functionality or safe shutdown.
