PVC Double Union Ball Valve for Pressure Pipe

This PVC double union ball valve is designed to isolate, start/stop and manually regulate water flow in pressure pipe systems. It’s ideal for pond, koi and water feature installations where reliable shut-off and easy servicing are important.

Made from durable PVC, the valve body is corrosion-resistant and suitable for use in damp environments, including underground installations. The double union design allows the valve to be removed without cutting pipework, helping to simplify maintenance and upgrades.

A smooth internal bore helps reduce restriction through the line, supporting efficient circulation in filtration and pump setups. Use it wherever you need convenient isolation points on pressure pipe runs, such as before and after pumps, filters, UV units or manifolds.

Choose the required size and thread configuration (male, female, or mixed) to match your existing fittings. For best results, install in an accessible position so the handle can be operated easily and the unions can be undone when servicing is required.
