ABOUT FZV

Industrial Valve Manufacturing for Energy and Process Projects

FZV, Fangzheng Valve Group, manufactures industrial valves at facilities in Wenzhou and Shanghai, China. The company serves EPC contractors, project operators and specialist valve distributors purchasing for oil and gas, LNG, refining and power applications.

Product selection, manufacturing inspection and service support connect the valve requirement to the wider project specification.

A Product Range Built Around Project Requirements

A project valve schedule can include several operating duties, materials and connection types. FZV combines pipeline ball valves, cryogenic valves and pressure seal valves with gate, globe, check and butterfly valves for supporting pipework.

Ball valve products include floating, trunnion mounted, top entry, fully welded and DBB designs. The cryogenic range covers several valve functions, while API 6A valves and wellhead products address upstream equipment requirements. Each range has its own selection conditions and supply scope.

For buyers, this breadth provides a basis for discussing related valve requirements with the same manufacturer. Operating medium, pressure, temperature, maintenance access and equipment interfaces remain specific to each item.

Manufacturing and Technical Support

Machining and Assembly

FZV facilities include machining, welding and overlay, assembly and testing operations. These activities support the manufacture of valve bodies, internal components and complete valve assemblies, with construction requirements defined by the selected product.

Materials and Configuration

Material options across the product ranges include carbon steel, stainless steel, duplex steel and alloy materials. Body and trim selection, soft or metal sealing, end connections and operating methods can be discussed against the service specification. Availability depends on the valve type and configuration.

Support During Operation

Product consultation, usage training, maintenance and commissioning support complement valve supply. Product identification and operating information provide the starting point for discussing service requirements and the scope of assistance.

Inspection and Traceability

Valve evaluation involves more than the product name and pressure class. FZV inspection capabilities address materials, dimensions, construction and sealing requirements. Applicable checks and acceptance criteria are defined for the ordered product.

Material Checks Positive material identification, chemical analysis and mechanical testing capabilities support material verification. Tensile, impact and hardness testing address different requirements within the relevant specification.

Dimensions and Examination Dimensional inspection, wall thickness measurement and nondestructive examination support checks on valve construction. The examination method and coverage depend on the component and purchase requirements.

Pressure and Sealing Hydrostatic, pneumatic and fugitive emission testing capabilities support different verification needs. Test conditions and applicability must be established for the selected valve rather than assumed across every product range.

Product Records FZV maintains product information and supporting records for traceability. These records provide a reference for technical enquiries, maintenance discussions and service follow-up.
