Description

LK 521 MultiFill® is a compact combination valve for easy filling of refrigerant liquid in the collector hose of ground source heat pumps. The valve has a filter that protects the evaporator against any particles. In versions G25 and G32, the valve is supplied with insulation to protect against condensation and possible ice formation. In version G50, the valve is delivered without insulation. The valve's compact design makes it easy to install even in tight spaces. LK 521 MultiFill® can also be used in other applications that require filling and filtration. Arrows on the valve body indicate flow direction.

The valve should be insulated with the supplied insulation.
