American Standard gate valves are engineered and manufactured in strict accordance with API and ASME standards, featuring an advanced, aesthetically refined structure.
- Operating Principle: The valve utilizes a linear-motion gate (disc) that moves perpendicular to the fluid flow. Designed for isolation service, these valves must be either fully opened or fully closed and are not intended for throttling or flow regulation.
- Dual-Sealing Surface: The gate features two precision-engineered sealing faces with a standard 3° wedge angle, ensuring a high-integrity seal under pressure.
- Disc Variations:
- Rigid Wedge (Solid Disc): A single-piece construction offering high strength and simplicity.
- Flexible Wedge (Elastic Ram): Engineered to allow for micro-deformation. This design compensates for minor deviations in the sealing surface angle caused by thermal expansion or manufacturing tolerances, significantly improving sealing performance.
Design Excellence & Standards
Our gate valves are engineered and manufactured to ensure maximum service life and operational dependability. All units feature a full-ported design, meeting the rigorous design requirements of international standards, including:
- API 600 & API 6D: American Petroleum Institute Standards.
- BS 1414 & BS EN 1984: British and European Standards.
- ASME B16.34: American Society of Mechanical Engineers Standard.
We offer a comprehensive range of body, bonnet, and trim materials to suit specific industrial environments and fluid conditions.
Comprehensive Range of Materials
To meet diverse project specifications, we provide high-grade material options for various pressure and temperature requirements:
Body and Bonnet Materials
We supply nine standard grades of Carbon Steel, Low Alloy Steel, and Stainless Steel. For specialized or highly corrosive applications, we can manufacture valves in custom alloy grades upon request.
Trims and Seals
- Full Range of Trims: Tailored to match specific service media (Oil, Gas, Water, Chemicals).
- Custom Sealing: Optional packing and gasket materials are available to withstand a full spectrum of service conditions, from cryogenic temperatures to high-pressure steam.
