The Reflex MK 1 1/4 ball valve with cover is designed as a shut-off valve with a lock for safe maintenance and disassembly of diaphragm expansion vessels in heating, cooling, and solar systems. It allows for quick disconnection of the vessel from the system without the need for complex interventions in the piping.

The integrated drainage facilitates the emptying of the vessel and the connecting pipe, while the cover prevents unintended manipulation of the valve. The valve is constructed according to the requirements of the DIN EN 12828 standard and is suitable for use with Reflex expansion vessels in installations with higher operating pressure and temperature load.
