Cast Super Duplex Steel SDSS 5A 2500LB Gate Valve for Sea Water
API600 Cast Steel Gate Valve is specifically engineered and manufactured in full compliance with the API 600 Standard (Bonnetless & Bolted Bonnet Gate Valves for Petroleum and Natural Gas Industries), crafted from high-quality cast steel (WCB, WC6, WC9, C5, C12) to deliver exceptional performance in high-pressure, high-temperature, and harsh industrial environments. Designed for reliable on/off flow control of critical media, this gate valve features a robust cast steel body and precision-machined internal components, ensuring superior pressure resistance, corrosion resistance, and long service life—making it the preferred choice for petroleum, natural gas, petrochemical, and power generation industries worldwide.
Key Features
– API 600 Full Compliance: Strictly adheres to API 600 (6th/7th Edition) standards, covering design, material selection, manufacturing, testing, and marking, ensuring compatibility with global petroleum and natural gas industry requirements.
-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.
-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, radiographic 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.
