BRANCH CONN. CHECK VALVE NOTAP 21-23mm DN15/Cu22

With NoTap branch connectors, you can make repairs and connections without first draining the network. You save a lot of time and money, and the work is also very easy.

Branch connector with check valve: A check valve seat is used when making smaller branches, installing saddle taps, and punching pipes. When making branches, a coupling is used that opens the check valve. When drilling a hole for a saddle tap, an insertion pipe adapter is used. When punching a pipe, a ball tool is used to push the ball into the pipe.

Benefits:

• 1. The network does not need to be drained.
• 2. The network does not need to be refilled and vented, resulting in lower installation costs.
• 3. Installation is simpler because no welding, cutting, or soldering is required.
• 4. Can be used with all types of pipe materials, including black, painted, galvanized, stainless, thin-walled, and copper pipes. Note! Cannot be used on annealed pipes.
• 5. Saves energy because heated water does not need to be drained.
• 6. Can be used in heating, domestic water, compressed air, and cooling systems.
• 7. No hot work required.
• 8. Pipe corrosion is reduced because no new oxygen-rich water needs to be added.
• 9. Environmentally friendly because dirty water does not need to be discharged from the network.
• 10. No contaminants enter the network during the work phase.
• Follow local installation regulations!
