The American AFC OS&Y Resilient Wedge Fire Gate Valve is designed to isolate and control water flow within fire protection piping networks.
Its Outside Screw and Yoke construction provides a clear visual indication of the valve position because the stem rises when the valve opens and lowers when the valve closes.
This product page combines two models from the same valve family:
• A-3000: OS&Y gate valve with flanged ends.
• AG-3000: OS&Y gate valve with grooved ends.
Both models share the same basic construction, pressure rating, operating temperature, material specifications, available size range and fire protection approvals. The primary difference is the end-connection method.
Key Features:
• OS&Y fire protection gate valve.
• Resilient wedge construction for reliable shutoff.
• Rising stem provides a clear visual indication of valve position.
• Suitable for isolating fire protection piping sections.
• Available with flanged or grooved ends.
• Ductile iron valve body.
• Ductile iron wedge encapsulated with EPDM.
• Stainless-steel 304 stem, fasteners and internal components.
• Heavy-duty manual handwheel.
• Reliable manual operation.
• Internally and externally fusion-bonded epoxy coated.
• Coating complies with AWWA C550.
• Maximum working pressure of 300 PSI or 21 bar.
• Maximum test pressure of 600 PSI or 42 bar.
• Operating temperature from 0°C to 80°C.
• Available in sizes from 2.5 to 12 inches.
• UL Listed as shown in the catalogue.
• FM Approved as shown in the catalogue.
• Complies with AWWA C515.
A-3000 Flanged-End Model:
The A-3000 model is supplied with flanged ends compatible with the following connection standards:
• ANSI B16.1 Class 125.
• ANSI B16.42 Class 150.
• BS EN 1092-2 PN16.
Available Sizes:
• 2.5 inches.
• 3 inches.
• 4 inches.
• 6 inches.
• 8 inches.
• 10 inches.
• 12 inches.
AG-3000 Grooved-End Model:
The AG-3000 model is supplied with grooved ends for use with grooved mechanical couplings. Groove dimensions comply with AWWA C606.
Available Sizes:
• 2.5 inches.
• 3 inches.
• 4 inches.
• 6 inches.
• 8 inches.
• 10 inches.
• 12 inches.
Main Construction Materials:
• Valve body: Ductile Iron ASTM A536 65-45-12.
• Resilient wedge: Ductile Iron ASTM A536 with EPDM to ASTM D2000.
• Wedge nut: Stainless Steel 304.
• Stem: Stainless Steel 304.
• Bolts and fasteners: Stainless Steel 304.
• Bonnet: Ductile Iron ASTM A536.
• Yoke: Ductile Iron ASTM A536 65-45-12.
• Handwheel: Ductile Iron ASTM A536 65-45-12.
• Packing: PTFE Graphite.
• O-rings and gaskets: EPDM to ASTM D2000.
• Handwheel nut and yoke screw: C95400 Aluminum Bronze.
Operation:
The valve is manually opened or closed using the handwheel. As the handwheel rotates, the valve stem moves vertically outside the valve body, providing a visible position indication:
• A raised stem indicates that the valve is open.
• A lowered stem indicates that the valve is closed.
Applications:
• Automatic sprinkler systems.
• Fire hydrant systems.
• Fire hose networks.
• Fire pump suction and discharge piping.
• Fire protection water-distribution lines.
• Commercial and industrial fire protection systems.
• Isolation points within firefighting piping networks.
Standards and Approvals Shown in the Catalogue:
• UL Listed.
• FM Approved.
• AWWA C515.
• AWWA C550 for the protective coating.
• AWWA C606 for grooved-end dimensions.
• ANSI B16.1 Class 125.
• ANSI B16.42 Class 150.
• BS EN 1092-2 PN16.
The final model should be selected according to the project piping connection. Model A-3000 is used for flanged piping, while model AG-3000 is used for grooved piping.
