Double Union demountable ball valves offer the versaility of not only allowing control over the flow of water, but they can then allow for removal of items for maintenance reasons by shutting off the waterflow and undoing the valve coupling.
These Kockney Koi Ball Valves are available in several sizes. All Made to fit UK Pipe Sizes, however we also manufacture imperial to metric adapters if you need them.
These Collars are perfect to be used if you need to replace a part, as the collar will be glued into pipework sometimes they will not be salvageable, so you can now purchase these collars seperately. These are also useful if you are looking to transion from pressure pipework onto solvent weld, as you can replace the collar on a pressure ball valve so one side goes onto pressure and the other onto solvent weld.
