LK 523 Vacuum Valve

Description

LK 523 is a backsuction protection that is installed in heating and cooling installations. The vacuum valve can be installed in any position as the function is position-independent. However, installation in the system's low points should be avoided. The G½ connection is designed for LK Armatur's system with O-ring sealing. When connecting to this system, the valve is screwed by hand to the stop and then with a suitable tool another 0.5-1.5 turns. When connecting to another component, the thread is sealed in the usual way.
