Stainless Steel Flanged Gate Valve

Product Name & Standards Flanged Gate ValveCompliant with API 600, ASME B16.34, and ANSI B16.5 standards. Core Definition A specialized industrial valve featuring a flat gate disc designed to regulate fluid flow (on/off control) in metal valve-pipe systems. It achieves pipe connection via flanged joints, offering a robust and leak-tight interface for industrial and commercial piping networks. Structure & Operating Principle – Key Component: Flat gate disc (gate-like structure) – engineered for precise flow shutoff and startup. – Operation Mechanism: The gate disc is vertically raised (valve open) or lowered (valve closed) via the valve stem, enabling accurate, controlled fluid flow adjustment. – Connection Method: Flanged ends – bolted to matching pipe flanges for secure, easy assembly and maintenance. Performance Advantages – Exceptional reliability and long service life: Constructed with high-grade materials and rugged design, ensuring durable performance in continuous operation. – Precise flow control: Flat gate disc provides tight shutoff when closed, minimizing leakage and enabling accurate on/off regulation. – Versatile compatibility: Suitable for a wide range of industrial fluids and operating conditions, maintaining structural integrity over extended use. Key Specifications – Pressure Rating: PN10 – PN420 / Class 150 – 2500. – Operating Temperature: -29℃ – 425℃ (carbon steel body) / -196℃ – 550℃ (stainless steel body). – Body Materials: Carbon Steel (A216 WCB), Stainless Steel (A351 CF8/CF8M), Alloy Steel (A217 WC6/WC9). – End Connection: Flanged (ANSI B16.5, DIN EN 1092-1) – compatible with standard pipe flanges. Application Fields – Industrial Piping Systems: Oil & gas transmission, chemical processing, petrochemicals, power generation, water treatment, metallurgy, and pulp & paper. – Commercial & Infrastructure: Municipal water supply, HVAC systems, industrial boilers, and large-scale fluid transport pipelines requiring reliable on/off control.
