1, the installation location: balance valve can be installed in the water supply pipe can also be installed in the backwater pipe (each loop only need to install one). For the loop side of the thermal station, it is recommended that the counterbalance valve be installed on the return line with a lower water temperature for the purpose of balanced adjustment. Balance valve on the main pipe should be installed in the water supply pipe pump (downstream of the pump), to prevent the pump before (after the valve) the pressure is too low, the pump cavitation may occur. 2, try to install in the straight pipe section: Since the balance valve has a flow measurement function, in order to flow through the valve before and after the stable, to ensure measurement accuracy, conditions permitting should try to install the balance valve at the straight pipe section. 3, pay attention to the new system and the balance of the original system: When installing a new balance valve system connected to the original heating (cold) pipe network, we must pay attention to the new system and the balance of the original system of water distribution to avoid the installation of a balance The valve's new system (or retrofit system) has a higher water resistance than the original system and does not meet the required flow rate. 4, should not be free to change the balance valve opening: pipe network system installation is complete, and have the test conditions, the use of special intelligent instrumentation to adjust the balance of all valves set, and the valve opening of the lock to enable pipe network to achieve hydraulic conditions balance. In the normal operation of the pipe network system, should not be free to change the balance valve opening, in particular, should not change the opening degree of locking device. 5, no longer need to install the globe valve: In the repair of a loop, the balance valve on the loop can be closed, this time the balance valve to stop the flow of water cut-off valve role, overhaul and then back to the original locked position. Therefore, the installation of the balance valve, you no longer have to install the globe valve. 6. When system adds (or cancels) the loop, it should be readjusted again. When adding (or canceling) the loop in the network system, in addition to adding (or closing) the corresponding balancing valve, in principle, all new Balance valve and the balance valve in the original system loop should be re-commissioning (the original branch valve in the loop does not need to be re-adjusted).
