Other Valves | LK 538 ThermoFill EA LK 538 ThermoFill EA Technical Data 126 LK 538 ThermoFill EA is a filling valve for heating systems. The valve has an integrated shut-off/check valve which ensures opening even at low pressure differences. The check valve is inspectionable and classified as a back flow preventer Type EA according to EN 1717. The arrow on the valve body indicates the direction of the flow. Male threads are sealed in the usual manner. Both the inlet side as well as the outlet side are designed according to the LK Armatur O-ring seal system. When connecting to this system, tighten first by hand until stop, then another 0.5- 1.5 turns with an appropriate tool into the right position. It is easier to fit the compression fitting if a lubricant is applied to the thread and bevel. Tighten first by hand and then with a box spanner. Number of turns to be tightened with a spanner: See the separate datasheet for compression fittings. Soft pipes are to be fitted with a support sleeve.
