Purpose: These valves are designed to allow for the easy draining of water from a system—such as a radiator, boiler, or section of piping—when maintenance or repairs are required.

Design: * Ball Valve Mechanism: The lever handle (blue or red) allows for quick opening and closing of the flow.

• Hose Connection: The barbed end (on the right side of the valve in the image) allows for the attachment of a standard garden or drain hose to direct the water away from the system to a floor drain or exterior area.

• Protective Cap: The circular cap, attached by a leash, covers the outlet when not in use, preventing leaks or debris from entering the valve.

• Color Coding: The blue and red handles are typically used to distinguish between cold and hot water lines or to help installers identify return and supply circuits in a heating system.
