Key features

The ball valve with FEP lining layer has extremely high chemical stability and can be used for any strong corrosive properties except''molten alkali metal and elemental fluorine''.

Using a full bore,floating ball structure,the valve can be closed without leakage within the entire pressure range,facilitating ball purging and pipeline maintenance of the pipeline system.

The ball of the hoist and the stem are cast as a whole,eliminating the possibility of the stem rushing out of the pressure bearing part due to pressure changes,fundamentally ensuring the safety.

The structure is compact and reasonable ,with the smallest inner cavity space of the body ,reducing medium retention.

In addition,the special molding process makes the sealing surface have a good density,and the combination of herringbone ring PTFE packing makes the valve achieve zero leakage.

The two-piece and three-piece structure can adapt to various pipeline systems and operating conditions with different requirements.

The three-piece ball valve allows the main body to be separated from the bodies on both sides,enabling rapid online replacement and maintenance.

AI-Powered supplier vetting

SummaryThe supplier is a Zhejiang-based high-tech manufacturer focused on pumps, vacuum equipment, valves, hardware, metal products, and industrial automation components. It reports over 40 patents, recent new-product development, ODM services, and OEM work for well-known brands. Production is supported by machining, injection, CNC, welding, and pipe-machining facilities, 12 quality inspectors, documented finished-product inspection instructions, and valid contracts with associated subcontractors. Quality and sustainability systems include ISO9001:2015, ISO45001:2018, and ISO14001 certifications, while regular fire drills were conducted during the past year. The supplier has 18 years of export experience, with exports representing 51%–70% of total sales, and has participated in the Russian PVC Exhibition. However, it reports no SDK, inventory, overseas warehouse, overseas showroom, overseas agent or branch, and zero countries with overseas service coverage. Financial records are identified for 2023–2025, but no...

Supplier typeThe supplier identifies itself as a national high-tech enterprise, Zhejiang Made unit, and specialized and sophisticated enterprise. Its stated business scope covers manufacturing, pumps and vacuum equipment, valves and plugs, hardware, metal products, and industrial automation products, indicating a diversified industrial equipment manufacturer.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. It also reports other product-compliance certification, but the specific standard is not identified, so the assessment is supported primarily by the named management-system certificates.

After-Sales capabilityThe supplier reports no in-stock service capability, overseas warehouse, overseas showroom, overseas agent, or overseas branch, and lists zero countries where overseas services are offered. These stated limitations indicate weak overseas after-sales and local-service coverage.

R&D capabilityThe supplier reports more than 40 patents, including multiple national patents, and states that it developed new products during the past year. It also provides ODM and OEM services, although it explicitly reports no available SDK.

Production capacityProduction evidence includes valid manufacturing-capacity contracts with associated subcontractors, machining, injection, CNC, welding, and pipe-machining facilities, 12 quality inspectors, documented inspection instructions, and a one-month peak-season lead time. The supplier also reports 12 qualified service-capability suppliers and written procedures with follow-up records, supporting substantial production and quality-management capability.

Customization capabilityThe supplier reports customization from samples, ODM services, and OEM services for well-known brands. These statements directly support the ability to deliver customer-specific products and manufacturing solutions.

Product Q&A

Q:What is difference between two-piece & three-piece Q41F46 fluorine-lined ball valve?

Two-piece:Compact structure,competitive price.For maintenance,the whole valve must be removed from pipeline.Suitable for general chemical service. Three-piece:Split-body design.The middle cartridge can be maintained on-line without removing valve from piping.Easy replacement of ball & seats.Recommended for critical process lines,higher cost than two-piece type.

Q:Temperature&pressure rating,suitable media?

Nominal pressure PN10 / PN16;Working temp:-20~180. Resistant to most acids, alkalis,brines and organic solvents.Not for molten alkali metal & elemental fluorine.

Q:Can fluorine-lined ball valve do flow regulation?

Standard version is for ON/OFF shut-off only.Continuous throttling under partial-open position is not recommended.For modulating service,V-notch ball is required.

Q:What parameters required for order?

Model number, two-piece or three-piece,DN,PN,body material(WCB/CF),lining F46,F4,PFA,actuator accessories,process media & temperature.

Q:Installation tips?

1.Protect fluorine-lined flange face against scratch and impact. 2. Tighten flange bolts diagonally and evenly. 3. Clean pipeline before installation to avoid particle damage. 4. Do NOT use valve as throttling device under partial-open.
