Standard PPR green valve – 40mm size – water flow control
A green polypropylene (PPR) manual shut-off valve designed to control the opening and closing of water flow within plumbing systems. It mounts directly to PPR pipes using thermal welding to ensure a tight, leak-free connection in residential and commercial installations.
Features
- Direct installation by thermal welding onto PPR pipes without the need for cutting or complicated connections.
- Simple manual control to open and close the water flow.
- It is resistant to corrosion and deposits due to its lack of internal metals.
- Robust design for long-lasting operation with low maintenance.
- Green color to match standard PPR tubing systems for easy identification.
- Suitable for use in drinking water networks and public plumbing (according to system specifications).
Technical specifications
- Type: Standard manual stop valve (Stop/Valves).
- Material: PPR (Polypropylene).
- Nominal diameter: 40 mm.
- Installation method: Direct thermal welding on PPR pipes.
- Color: Green.
- Usage: Indoor, residential and commercial plumbing systems.
Quick Installation Instructions
- Cut and trim the end of the pipe at a right angle and clean it of dirt and oil.
- Set the torch/heat welding device to the appropriate temperatures for the PPR material.
- Heat both ends (the pipe and the socket in the valve) according to the welding machine instructions.
- Push the two ends together straight and wait a few seconds for the joint to cool and harden.
- Check the connection by using a pressure test to ensure there are no leaks.
Safety and maintenance tips
- Make sure you use the appropriate heat welding tools and follow the manufacturer's instructions.
- Do not use the valve with strong chemical liquids or gases without checking the material specifications.
- Regularly inspect the connections and welded joints to ensure they are free of leaks.
- To prolong the life of the valve, avoid frequent violent operation and be sure to clean the system when needed.
