OS&Y Gate Valve Grooved End Fire Protection UL/FM Approved Overview

OS&Y gate valves with grooved ends are a type of valve that is commonly used in fire protection systems. They are designed to provide a tight shut-off when the valve is closed, which is essential for preventing the spread of fire.

These valves are available in a variety of sizes and pressure ratings to suit different needs. Common sizes range from 1/2 inch to 12 inches, with pressure ratings up to 300 PSI.

Construction

OS&Y gate valves with grooved ends are constructed of cast iron or stainless steel. The valve body and bonnet are made of the same material, and the disc, seat, stem, and handle are also typically made of the same material.

The valve body is the main housing of the valve and is typically threaded on both ends. The bonnet is a cover that screws onto the body and houses the valve’s internal components. The disc is the movable component that controls the flow of fluid. The seat is the surface against which the disc seals when the valve is closed. The stem is the rod that connects the disc to the handle. The handle is used to manually open and close the valve.

The grooved ends of the valve are designed to mate with grooved fittings. This provides a leak-tight seal when the valve is closed.

Performance

OS&Y gate valves with grooved ends are designed to meet the requirements of the Underwriters Laboratories (UL) and Factory Mutual (FM) fire protection standards. These standards ensure that the valves are capable of providing a tight shut-off under fire conditions.

These valves are typically used to shut off the flow of water, steam, or other fluids in fire protection systems. They are a good choice for applications where a tight shut-off is required to prevent the spread of fire.
