Product Name & StandardsFlanged Gate ValveCompliant with API 600, ASME B16.34, and ANSI B16.5 standards.
Core DefinitionA 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.
