FlowCon K DN15-80 (1/2”-3”) 1K95000 - 06/2023 Installation and Operation Instruction Install the FlowCon K as called for in the design drawings. INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL ARROW POINTING IN THE CORRECT DIRECTION. The FlowCon K valve (Model Nos. F38X.0.X.X) is available with fixed female-by-female threaded connections for all model sizes. The thread standard for the K model is either ISO 228, which is a straight metric thread (com- patible with BS-2779) or NPT threading stan- dard, depending on the product number ordered. For all pipe threads or P/T threads FlowCon re- commends thread sealant (Permabond A1044 or equivalent). If sealant such as pipe dope is used, please ensure no strands are left in the valve or piping. When using Teflon tape, FlowCon recommends 3-5 rounds of Teflon are used. The Teflon tape has to be applied tightly in clockwise rotation. Figure 1 IMPORTANT: Never use mineral oil or petrol based grease or oil on the o-rings. When insert- ing the insert, be assured to check the place- ment of the o-ring. There is no need to use tools - the insert can be inserted/removed by the fin- gers. Also the 3” insert is mounted with an o-ring (DN50/65/80 valve bodies as in Figure 3). NOTE: 2” inserts used in valve bodies size DN40 and DN50 (Figure 2) are mounted with- out o-ring. Figure 2 Pressure/temperature fittings (p/t plugs) are available upon request for the K valve. Before finger mounting the p/t plugs in the body tap- pings, please seal the threads of the p/t plugs (DO NOT OVER TIGHTEN). Alternatively to p/t plugs, the valve body can be ordered with plugs for the body tappings. Each plug is sealed by a gasket. Figure 3 Inserting the insert: For FlowCon K valve bodies size DN15-DN40 (Figure 1) a 3/4”, respectively a 1 1/2” stainless steel insert is inserted. It is recommended that the o-rings located around the insert and cap are lubricated with silicone grease, before the insert is installed into the valve body.
