ISO15761 Forged Steel F2 3in Gate Valve with Integral Flange End
Forged Steel Gate Valve is precision engineered and manufactured in full compliance with API 602 or ISO15761 Standard (Compact Steel Gate Valves, Flanged and Threaded Ends)—the global benchmark for small-bore, high-pressure forged steel valves. This valve features a fully forged body, bonnet and internal components for exceptional structural density, pressure resistance and impact toughness, eliminating casting defects and ensuring reliable on/off flow control in small-diameter, high-pressure industrial piping systems. Optimized for compact installation spaces and critical low-flow applications, it is the industry’s top choice for petroleum, natural gas, petrochemical and power generation small-bore high-pressure pipelines worldwide.
Key Features
-High-Grade Cast Steel Construction: The requests for CE,Impact test,NACE,Corrosion Allowance,PREN,Pitting test can be met.
– Robust Sealing Performance: Adopts metal-to-metal hard sealing (stellite overlay on gate and seat) for superior sealing reliability, zero leakage under rated pressure and temperature, and excellent wear resistance for frequent on/off operation in critical piping systems.
-Compact & Space-Saving Structure: API 602 optimized compact design with short face-to-face dimensions, perfect for small-bore pipelines, instrument skids, valve manifolds and tight installation spaces in refineries and chemical plants—lightweight yet robust for industrial harsh conditions.
-Strict Quality Testing: Every valve undergoes API 600-mandated hydrostatic pressure test (shell, seat, and stem packing) and air tightness test, with optional NDT (Non-Destructive Testing) including ultrasonic testing,and magnetic particle testing to ensure product integrity.
– Easy Maintenance: Bolted bonnet design for easy disassembly and maintenance; precision-machined stem with anti-friction packing (PTFE, graphite-low emission optional API624) to reduce operating torque and prevent stem leakage, extending service life.
-Versatile End Connections: Multiple end connection options for small-bore piping needs, with precise machining to meet ANSI standards for leak-free assembly.
