PVC sliding gate valves provide a manual open and close point in charged rainwater pipework, allowing a water-filled line to be drained when required.
The valve uses a plastic sliding paddle operated by the handle at the top. Pulling the handle up raises the paddle out of the flow path to open the valve, while pushing it down lowers the paddle across the pipe opening to stop the flow.
Female sockets on both sides of the valve fit over matching PVC DWV pipe and are solvent welded into the pipeline. The valve can be installed in either a horizontal or vertical pipe run.
These valves are particularly useful in charged rainwater systems, where sections of pipe remain full of water between rain events and may need to be drained for cleaning, maintenance or other work.
The valve has a maximum pressure rating of 210 kPa. Maximum pressure across the paddle while it is part-way through opening or closing is 5 kPa, so the valve is intended primarily for fully open or fully closed operation rather than throttling flow.
