Installation of self-actuated flow valve, self-actuated differential control valve, removed a lot of the situation. In addition to the use of counterfeit balance valve, and the majority of users due to the installation of self-actuated flow valve, self-actuated pressure differential control valve misunderstanding. Flow valve can not provide pressure head, can only eliminate the extra pressure head. which can be installed in the end of the pressure head is not enough self-actauted flow control valve or self-actuated pressure differential control valve to increase the resistance, will cause the system pressure head is insufficient, this is the reason for the removal, and valve manufacturing has nothing to do. For the existing building heating system transformation, due to the installation of balance valve, heat meter to increase the resistance will cause the system pressure head. So the installation of the system before the need for hydraulic balance and system pressure check. It is forbidden to install.
