Watts Alimat Filling Valve

The ALIMAT filling valves connect a sealed heating system to the water main thus ensuring rapid automatic make-up of any water lost by the heating system. This is done by very accurate and reliable adjustment of the pressure of the heating system until reaching the required operating pressure and also with protection against reverse flow which could cause contamination of the water main.

The valves of the AL e ALM Series combine the following functions:

• pressure control
• automatic non-return
• shut-off
• filtration
• pressure monitoring
• air conditioning and air handling systems.

Automatic filling valve complete with check valve, manual shut-off, stainless steel filter, vent screw. 

Body made of brass CW617N. High impact plastic cap.
