ALD automatinis papildymo vožtuvas 0.5-3 bar

Aprašymas

ALD automatinis papildymo vožtuvas 0.5-3 bar, kodas 10004877.

Papildymo vožtuvai naudojami šildymo sistemai papildyti.

Jie neleidžia įvykti gedimams dėl slėgio viršijimo papildant sistemą. Tai užtikrinama, kai pasiekus nustatytą maksimalų darbo slėgį, papildymo srovė nutraukiama.
Įmontuotas atbulinis vožtuvas neleidžia šilumos nešėjui patekti į geriamo vandens sistemą.

Main features – Filling valves ALD

Designed for automatic filling of sealed heating systems and for protection of the water mains from risk of contamination.

• Available with threaded connections DN 1/2”.
• The filling valves combine 5 functions, namely :
  • Pressure control
  • Automatic non-return
  • Filtration
  • Shut-off
  • Pressure measurement via pressure gauge

Description

Filling unit to fill closed heating installations in combination with backflow preventer according to EN 1717. Brass body, plastic cap, with integrated check and shut-off valve, pressure gauge connection 1/4”, hose nozzle, adjustment range 0,3 – 4,0 bar, connection 1/2”.

Operation

When the pressure exerted by the fluid inside the system drops below the pressure exerted by spring of the ALIMAT sfilling valve on diaphragm, the spring pushes plug downwards.
The mains water flows via inlet, through filter cartridge, then rises into chamber and opens check valve whereupon it flows into the system (U).
When filling of the system is complete, the pressure in it increases, and therefore in chamber. After exceeding the value balanced by the force exerted by the opposing spring, the pressure pushes diaphragm upwards while plug closes.
Check valve prevents back flow. Hence the pressure settles according to the set pressure given by the spring.
