Carlo Poletti - 5 Ports 16mm Valved Manifolds extension while at the same time

while at the same time eliminates the disadvantages of both materials when used in isolation

- Will not rot or corrode

In addition

A Non-Return Valve allows liquid to flow in one direction only

It is very important that the valve is fitted the right way around so that the water passing through pushes up on the jumper for this reason an arrow is stamped on the body indicating direction of flow

Carlo Poletti - 5 Ports 16mm Valved Manifolds extension while at the same timeDESCRIPTION: Each manifold is provided with red coloured valve heads fitted. Included with each is a set of blue coloured which are simple to change. Valved manifolds may be used for a wide range of applications and not just for radiator circuits. Both hot and cold water services can be provided by manifolds at central control points, much like the process used for electricity distribution. Such arrangements would enable isolation of individual "wet
