15mm Brass Cock Valve

A brass cock valve, often referred to simply as a “cock valve” or “ball valve,” is a type of quarter-turn valve that controls the flow of fluids by using a perforated, hollow, and pivoting ball (usually made of brass) within its body. Here is a detailed description of a brass cock valve:

1. Material:
   • The main body of the valve is made of brass, a durable and corrosion-resistant alloy composed primarily of copper and zinc. The ball inside is also typically made of brass.
2. Design:
   • The valve has a spherical or cylindrical-shaped ball with a hole through its center. The ball is positioned inside the valve body, and a lever or handle is attached to the ball’s top. When the handle is turned 90 degrees, it rotates the ball within the valve, either allowing or blocking the flow of fluid.
3. Operation:
   • Brass cock valves operate on a quarter-turn principle, meaning they can be fully open or fully closed with a 90-degree rotation of the handle. This design allows for quick and efficient control of fluid flow.
4. Handle:
   • The valve has a lever or handle that is typically perpendicular to the pipe when the valve is in the closed position and parallel to the pipe when the valve is open. This makes it easy to visually determine the valve’s status.
5. Sealing Mechanism:
   • The valve features a sealing mechanism, usually made of rubber or another resilient material, which provides a tight seal when the valve is closed. This design minimizes the risk of leaks.
6. Types:
   • Brass cock valves come in various types, including:
     • Full Port Valve: The ball has a bore diameter that matches the inner diameter of the pipe, allowing for maximum flow.
     • Reduced Port Valve: The ball has a smaller bore diameter, restricting the flow to some extent.
7. Applications:
   • Brass cock valves are widely used in plumbing, water distribution systems, industrial processes, and applications where a reliable and easily operated shut-off valve is required.
8. Advantages:
   • Brass cock valves offer several advantages, including durability, resistance to corrosion, ease of operation, and the ability to provide a quick and complete shut-off.
9. Sizes:
   • Available in various sizes to accommodate different pipe diameters, with standard sizing conventions to ensure compatibility with existing piping systems.
10. Maintenance:
    • Generally, brass cock valves require minimal maintenance. Periodic inspections can help identify any signs of wear, corrosion, or potential issues.

When selecting a brass cock valve, it’s crucial to consider factors such as the type of fluid, pressure requirements, and the specific needs of the application. Proper installation and routine maintenance contribute to the valve’s longevity and optimal performance in a piping system.
