A Compression 22mm Red Handle T-Bar Butterfly Valve is a valve designed for controlling the flow of liquids or gases in plumbing systems. It features a 22mm compression fitting, allowing it to be easily connected to pipes without the need for welding or soldering. The valve is operated by a red T-bar handle, which makes it simple to open or close the valve by rotating the handle. The butterfly valve mechanism uses a disc that pivots to regulate flow, offering quick and efficient flow control. This valve is typically used in larger plumbing systems, such as for heating, water distribution, or industrial applications, where a 22mm pipe size is required.
