5 Notes Engineering We recommend installation in the return pipe, as the temperatures in this pipe are lower for applications in heating systems, which in turn, extends the stem sealing gland's life. Water quality requirements as per VDI We generally recommend to install a strainer to increase the valve's functional safety. For media below 0 C, use the electric SZ6.5 stem heating element to prevent the valve stem from freezing in the sealing gland. For safety reasons, the stem heating element has been designed for C 24 V / 30 W operating voltage. Use the 3-port valve VXI4 primarily as mixing valve Mounting oth valve and actuator can easily be assembled at the mounting location. Neither special tools nor adjustments are required. The valve is supplied with mounting instructions no Mounting positions Z0 Direction of flow When mounting, pay attention to the valve's flow direction symbol: 2-port 3-port mixing 3-port diverting Commissioning Commission the valve only if the actuator has been mounted correctly. Stem retracts: Increasing flow Through-port opens, bypass closes Stem extends: Decreasing flow Through-port closes, bypass opens Service Stem sealing gland For actuator service work: Turn off the pump and the operating voltage, close the shutoff valves, depressurize the pipes and allow them to cool down. Disconnect the electrical connections, where required, from the terminals. Re-commission the valve only if the actuator has been mounted correctly. The glands can be exchanged without removing the valve, provided the pipes are depressurized and cooled off and the stem surface is unharmed. If the stem is damaged in the gland range, replace the entire stem-plug-unit (on 2-port valves only). Contact your local office or branch.
