What are the available connection types?

The standard connection is wafer, but flange connection sizes can be customized according to GB/T9113, ASME B16.5, or JIS B2220.

What is the nominal pressure class?

The valve supports Class 150, PN10, and PN16 pressure ratings.

How does the valve reduce maintenance costs?

The design minimizes wear and tear by preventing the disc from rubbing against the seat, ensuring long service life and low maintenance.

AI-Powered supplier vetting

SummaryZHENGZHOU FREE FLUID CONTROL TECHNOLOGY CO., LTD is a limited company specializing in valves, with valid import/export licensing and substantial export reach. It offers OEM, ODM, and multiple forms of customization, while exporting to a broad set of global markets and holding seven years of export experience. However, the supplier has only two employees, no cooperative suppliers, no inventory, overseas warehouse, overseas showroom, overseas agents, or branches, and has not participated in offline trade shows. Service-management documentation is weak: approved-supplier records lack signatures or dates, and no written procedures or records were identified for corrective actions or complaint handling. The supplier does not provide 3D software design, has had no new products in the past year, and lacks an SDK. Financial information is only represented by reporting years, without performance values. An audit by TÜV Rheinland is recorded, but the audit result is listed as 0 and the report validity shown ended...

Supplier typeThe supplier is identified as a limited company with no larger-company affiliation, two employees, and valves as its primary product. It also holds a valid import/export license, indicating an independently operated trading and manufacturing entity with export authorization.

After-Sales capabilityThere are no written procedures or records for customer complaint handling or corrective and preventive actions. The supplier also lacks inventory, overseas warehouses, overseas showrooms, overseas agents, and branches, limiting documented and geographically supported after-sales infrastructure.

R&D capabilityThe supplier provides ODM services, but it does not provide 3D software design, reported no new products during the past year, and has no available SDK. These explicit limitations indicate weak evidence of current product-development and software-enabled innovation.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM and OEM services, demonstrating broad stated customization capability despite lacking 3D software design.

The disc and body are made of stainless steel, while the seat is available in fluorine rubber or EPDM.

Q:What is the operating temperature range?

The valve operates within a temperature range of 0 to 200 degrees Celsius.

Q:Can the valve color be customized?

Yes, colors can be customized according to customer requirements.

Q:What industries is this valve suitable for?
