Available Configurations
Flanged OS&Y Gate Valve
Designed for piping systems with flanged connections. Verify the flange standard, pressure class, bolt-hole pattern, and face-to-face dimensions against the selected model to ensure compatibility with the existing or planned pipeline.
Grooved OS&Y Gate Valve
Designed for piping systems using grooved mechanical connections.
Configuration Availability
Available sizes and pressure ratings may vary by connection type. Specify the required configuration and nominal size when requesting a quotation.
Sprinkler DesignConstruction and Operating Design
Outside Screw and Yoke (OS&Y) Design
The rising stem provides visible valve position indication. Operators can identify the open or closed position from the external stem position during routine inspection and maintenance.
Cast Iron Valve Body
Confirm the body material grade and internal component materials in the datasheet for the selected model.
Gate-Type Shut-Off Mechanism
The gate mechanism is designed for on/off flow isolation rather than routine throttling. For reliable operation, the valve should be operated in accordance with the manufacturer's instructions.
Dimensions and Connection Details
Flanged Connection Dimensions
Check the flange standard, pressure class, bolt-hole pattern, and face-to-face dimensions against the model-specific drawing.
Grooved Connection Dimensions
Check the groove profile, dimensions, nominal pipe size, and coupling compatibility against the model-specific drawing and connection requirements.
Dimensional Drawings
Request a drawing for the exact model, nominal size, and connection type to verify installation dimensions and interface compatibility before ordering.
