The failure of the valve installation does not meet the requirements will result in great waste. On the contrary, proper installation can ensure the normal start of operation and prolong the service life. Reduce maintenance workload and achieve good system control performance. (1) the installation of the regulator shall, in general, consider the following aspects: safety: safety of personnel and equipment during installation. Circulating control performance: the pressure loss of the piping system should be consistent with the pressure loss considered in the calculation of the valve size to ensure the required flow characteristics. Import and export should be ensured as much as possible. Attach position: there shall be sufficient space for operators to operate manually (including bypass operation) and to ensure the possibility of local disassembly and repair of control valves and accessories. Generally, the bypass valve of the shut-off valve and the regulating valve are installed in the process of piping to meet the continuous operation needs of the equipment. Use the cut-off valve for isolation when repairing the regulating valve. Adjust with bypass valve. The following figure recommends the layout of the control valve set
