LK 548 is AquaKit a valve combination for water heating consist-

ing of a shut-off/check valve and a thermostatic mixing valve. The

shut-off valve closes the cold water inlet and has an integrated

check valve preventing recirculation of warm water into the in-

coming cold water pipe. The mixing valve regulates the supply of

cold water in order to achieve the desired temperature. The shut-

off/check valve has two connections with female thread M 1⁄2” for

fitting of a safety relief valve, vacuum breaker or filling valve.

Arrows on the valve body indicate the direction of the flow.

KV = incoming cold water

VV = incoming hot water

BV = outgoing warm water

Female thread connections are designed for the LK Armatur

O-ring seal system. Other components are fitted in the usual

way. When fitting to a male thread connection, adapter LK 373 is

used - see under Accessories.
