Gunmetal grease chamber head parts for KFR valves with non-rising stem
The Bender gunmetal bonnets with inner pre-loaded spring and teflonised stem are used for the shutting off function at DVGW-certified free-flow stop valves. The grease chamber without dead space prevents stagnating water, germs or limestone, and is therefore considered legionella-safe.
The advantage of the non-rising stem is that in tight places the stem does not raise out of the valve when it is opened. The patented SOFT actuation system ensures long-lasting smoothness.
