R554I

End piece for manifold

Description
The R554I valve is a terminal for manifolds. It has an automatic air vent and is fitted with a self-sealing gasket and outlet.
Suitable for sanitary distribution, heating and cooling systems with water and glycol solutions.

Operation
The operating principle of the automatic air vent valve is based on the concept of objects floating in a liquid.
When there is no air accumulation in the valve cylinder, the float is up and keeps the shutter closed thanks to the mechanism. The float lowers when
air accumulates in the cylinder, and this causes the opening of the shutter and the subsequent venting (which continues until the initial conditions are
restored).
