It is a hydraulically operated valve guided by a solenoid valve. The solenoid valve can be powered by 220V AC or 24V DC, and can be either normally open or normally closed according to various occasions.
The adjustable flow control dynamic balancing valve is used in water systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning. A one-time adjustment before operation can automatically keep the system flow constant at the required set value. It can automatically balance the system flow at the required set value; it can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by the user, overcome "uneven cold and hot", and improve the room temperature qualification rate of heating and air conditioning. It can effectively overcome the unfavorable operating mode of "large flow, small temperature difference", improve the system energy efficiency, and achieve economic operation. The applicable pressure difference range is 20-300KPa. When the working pressure difference of the system fluid exceeds 300KPa, measures should be taken to consume the excess pressure difference to prevent noise. The dynamic balancing valve does not have a shut-off function, and a shut-off valve should be set as needed.

As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high head and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impellers flows into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter; the pump casing is horizontally opened, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double-suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and the inlet and outlet pipes; the impeller structure of the double-suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

The self-operated differential pressure control valve is a valve that uses the pressure change of the medium itself to control itself and keep the pressure difference of the medium flowing through the controlled system unchanged. It is suitable for the pressure difference control of the double-pipe system in the heating mode to ensure that the system remains basically unchanged, reduce noise, balance resistance, and eliminate heat network and hydraulic imbalance. The self-operated flow control valve is used in water systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning.
