FlowCon DPCV DIFFERENT PRESSURE CONTROL VALVE INSTALLATION AND OPERATION INSTRUCTION FlowCon DPCV 15-50mm Install the FlowCon DPCV in the return pipework of the riser with connection to the supply pipework of the riser through the capillary tube as called for in the design drawings. It is recommended that a strainer be installed prior to the inlet of the capillary tube to prevent damage or blockage due to debris. INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL TRIANGLE POINTING IN THE CORRECT DIRECTION. For each end of the capillary tube start by mounting the big nut with the gasket () in the valve and proceed as shown in figure 2. Pull the small nut () onto the copper tube () with the thread toward the end of the tube, and then push the cutting ring () onto the tube as far as possible. Push the copper tube into the hole of the big nut and screw the small nut into the big nut with a wrench using 12-15Nm. Figure 2 Figure 1 The valve body is available with female threaded end connections. The thread standard is EN 10226-1, which is a straight metric thread. Please clear threads on both valve and piping of debris. Sealant such as pipe dope or Teflon tape is recommended. WHEN USING HEMP AS PIPE SEALANT, ENSURE NO STRANDS ARE LEFT IN THE VALVE OR PIPING. The capillary tube is available with ¼” straight male end connections with gaskets for sealing. One end is mounted on the upper part of the DPCV instead of the black plastic plug. The other end is mounted at the inlet of the riser fx. in a FlowCon ABS. When the DPCV is installed with the capillary tube in place and the system is operational, please vent the capillary tube as shown in figure 3. Open the highest elevated screw byturning it counter-clockwise max. 2 rotations until water runs constantly from it, and then close it again. Figure 3 As standard, the valve body is supplied with plugs in the body tappings. Each plug is sealed Denmark Dubai USA Singapore -1- FlowCon International assumes no responsibility for mistakes, if any, in any printed material. www.flowcon.com 1H95000 - 04/2016
