Automatic DZR brass air vent for bleeding air from heating and cooling systems.
The HERZ 2622-1X Bronze Swing Check Valve from HERZ Armaturen is designed for preventing reverse flow in closed-loop systems such as heating, cooling, and plumbing installations.
Manufactured from bronze (CC491K), the valve ensures high corrosion resistance and operational reliability. Its self-acting disc design allows one-directional flow with minimal pressure loss.
The valve operates silently, requires no maintenance, and can be installed in horizontal or vertical positions. It is suitable for non-aggressive media including hot and cold water or compressed air.
