LK 537 ThermoFill® EB/EA

LK 537 ThermoFill® EB and EA are filler valves for heating systems. The valves have an integrated shut-off with ball valve and non-return valve, which ensures opening even at low differential pressures. LK 537 EB can also be used as a shut-off valve in tapwater systems. The non-return valve in LK 537 EA can be inspected, which means it is classified as a backflow preventer type EA according to EN 1717.
The arrow on the valve body indicates the direction of flow.
External thread is sealed in the usual way, alternatively G ¾” flat coupling with rotating nut and flange gasket.
The valve requires no maintenance. The installation should be checked regularly.
