Product features: the regulating valve is mainly composed of valve body, sleeve, valve disc, valve rod and other parts
Both the sleeve and the valve disc are provided with orifices to change the flow area and regulate the flow through the rotation of the valve disc in the valve seat
Equipped with zkj or other electric angular stroke actuators, remote control and automatic control can be realized
Regulating valve is widely used in water supply pipeline for regulating flow
It can also be used in oil pipeline

Product performance: (1) since there is no need for system debugging, it saves a lot of trouble, saves the time of Da and shortens the completion date; (2) Since the valve group and the valve used for layered control are not used, you can save more pipes, insulation materials, installation costs and time; (3) The water system is always in a balanced state, so the water system balance will not be affected no matter whether the equipment is installed or used in the Fen period (4) Even if the water system design of some areas needs to be changed due to the change of some uses in the later stage of the project or after it is put into operation, it will not affect the water system design of other areas, let alone the water system balance of other areas
(5) Because the whole system is in a dynamic equilibrium state, the refrigeration unit and water pump will operate in a Zui energy-saving state, saving Da maintenance costs
(6) Because the flow balance of the system is automatic, the installation and maintenance are more convenient, and the possibility of balance destruction by human operation errors is eliminated
