F4 Type Raised Face Flanged Gate Valve, Split Body Design
Product Overview
Our F4 Type Flanged Gate Valve with Split Body is engineered for superior performance and reliability in industrial piping systems requiring full-open or full-close service. Its robust split-body design ensures exceptional maintenance convenience, while the F4 (Raised Face) flange connection guarantees a secure and leak-proof seal under demanding conditions. This valve is the optimal choice for applications in petrochemical, power generation, water treatment, and general process industries where durability and ease of service are paramount.
Key Features & Advantages
  • Split Body Design: The valve body is constructed in two sections, bolted together at the centerline. This innovative design allows for quick and easy inspection, maintenance, or replacement of internal components without removing the valve from the pipeline, drastically reducing downtime and maintenance costs.
  • F4 Raised Face Flange End: Features a standard F4 (RF) flange face according to GB/JB standards, compatible with international Raised Face flanges (ASME B16.5). This ensures a tight seal with a gasket and prevents leakage in high-pressure applications.
  • Rigid Wedge Disc: The solid wedge disc provides a tight, bidirectional seal, suitable for a wide range of fluids including water, oil, gas, and steam.
  • Rising Stem (OS &Y): The outside screw and yoke design provides a clear visual indication of the valve position and keeps the threaded stem section outside the valve body, protecting it from corrosive media.
  • Robust Construction: Manufactured from high-quality carbon steel (WCB/A105) or other alloys (SS304, SS316, etc.) to ensure long service life and resistance to corrosion and erosion.
  • Standard Compliance: Designed and manufactured in accordance with GB, JB standards, and compatible with key dimensions of ASME B16.34, B16.10, and B16.5.
