Clamp without check valve

The clamp with a check valve is used for smaller branch connections (14-125 mm), installing an immersion pipe adapter and for blocking. For branch connections, a connector is mounted on the clamp that opens the check valve. For immersion pipes an adapter is mounted, and for blocking a balloon tool is used for inserting the balloon into the pipe.

Technical Data for Clamp with Check Valve

Dimension Guides

A variety of different types of branch connections are available. See the NoTap Guide for tables matching the correct dimension of pipe, drill size and clamp article numbers.

Clamps with check valves are always used when pipe blocking (14-60,3 mm) and even for smaller branch connections. For branch connections, use one of our connectors which have a collar that opens the check valve.

For pipes with diameter 14 – 125 mm

• Straight or angled mini ball valve, Cu15 (G½")
• Optional valve with G½" or R¾" pipe thread

Clamp with check valve

The clamp without a check valve is used when larger branch dimensions (26 - 335 mm) are desired for maximum flow from the branch connection. A full-flow ball valve shall always be fitted on these clamps when work is to be carried out on pressurized pipes.

Key Applications

Installation of new water outlet

You can make simple branch (T-pipe) connections in the kitchen or bathroom for installing, for example, a new washing machine, dishwasher, coffee maker or other household machines.

Installing new connections

NoTap allows you to easily connect additional piping to existing heating, water and cooling systems in the building. One example would be connecting a new radiator.

Installing gauges etc.

With the NoTap adapter for immersion pipes, a temperature gauge or other measuring device can easily be installed without draining the system.

Heating equipment

With NoTap you will totally avoid problems associated with heating equipment such as welding, soldering, etc.
