Descrição de produto
GOST Cast Iron Gate Valve Double Flange WCB
This Double Flange Gate Valve is engineered for demanding industrial applications requiring reliable isolation in pipelines. Manufactured with a robust WCB (A216 Grade WCB) carbon steel body and bonnet, it offers superior strength and excellent resistance to high temperatures and pressures. The valve conforms to GOST standards, ensuring compatibility and performance specifications for markets and projects requiring adherence to these norms.
Key Features & Specifications
  • Body & Trim Material: Primary components are constructed from ASTM A216 WCB carbon steel. Internal trim (seat, wedge/disc) is typically furnished with 13% Chrome (410) stainless steel or harder alloys based on service conditions, providing enhanced erosion and wear resistance.
  • Design & Construction: Features a full-bore design for minimal pressure drop and piggable pipelines. The sturdy, double-flanged ends (conforming to GOST flange standards) facilitate secure bolting into the piping system. The valve utilizes a flexible wedge or solid wedge design (depending on model) to ensure tight sealing and compensate for potential seat wear or thermal expansion.
  • Standards & Compliance: Designed, manufactured, and tested in accordance with GOST standards (including but not limited to GOST 9544, GOST 33259, etc.) for dimensions, pressure ratings, and quality. Also incorporates relevant API, ANSI, and ASME design principles where applicable.
  • Pressure & Temperature Ratings: Suitable for a wide range of services. Typical pressure class ratings correspond to PN16, PN25, PN40, or Class 150, Class 300 equivalents under GOST. Suitable for working temperatures from approximately -29°C to +425°C, depending on seal materials.
  • Operational Mode: Standard operation is via a handwheel (rising stem design for clear visual indication of open/closed status). Options for gear operation are available for larger sizes or higher pressure applications. Can be adapted for automated actuation (electric, pneumatic, hydraulic).
  • Sealing & Performance: Metal-seated design ensures reliable service in high-temperature environments. Graphite packing provides effective stem sealing. The valve is designed for bidirectional sealing, offering shutoff capability regardless of flow direction.
  • Applications: Ideal for isolation service in a wide array of industries including oil & gas, petrochemical, power generation, water supply networks, and industrial process plants. It handles fluids such as water, steam, oil, gas, and non-aggressive chemicals.
  • Testing: Each valve undergoes rigorous individual testing, including shell strength test, seat leak test (bubble-tight per GOST requirements), and backseat test to guarantee integrity before shipment.
