How does the double disc structure improve sealing?

A spring is inserted between the double valve discs to ensure self-sealing through bi-directional flexible preload pressure, providing low-pressure bi-directional sealing without dust clogging.

What are the available size ranges?

The size range is NPS2~NPS14, DN50~DN350.

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.

Product Q&A

Q:What materials are used for the sealing surfaces?

The sealing pair is made of structural ceramics, which provide perfect performance to resist wear and flushing. The seat is also ceramic.

Q:How does the valve prevent clogging?

The valve disc has a rotational motion that avoids ash deposition on the sealing surface during opening and closing. Additionally, a blow sweep port or automatic blow sweep device can be set on the valve body.

Q:Is the face-to-face dimension customizable?

Yes, the face-to-face dimension 'L' can be customized according to customer requirements. Colors can also be customized.

Q:What are the main applications for this valve?

It is mainly used in power plant ash handling systems, cement industry dry powder conveying and dumping, and dressing works for dry powder materials selection and conveying.

Q:What is the nominal pressure rating?

The nominal pressure is Class 150 / PN10 / PN16.
