The 800X differential pressure bypass balancing valve is a valve used to balance the pressure difference between the supply/return water of the air conditioning system. The 800X differential pressure bypass balance valve can improve the utilization rate of the system, maintain the mutual straightness of the pressure difference, and minimize the noise of the system and the damage caused to equipment by excessive pressure difference. The advantage of the 800X differential pressure bypass balance valve over other balance valves is that it does not have an actuator, and the pressure difference of the medium itself is used to achieve the function of the balance system, saving energy and installation space. It is an intelligent valve.

The 800X differential pressure bypass balance valve consists of a main valve, a differential pressure control pilot valve, a needle valve, a ball valve, a micro filter, and a pressure gauge to form a hydraulic control connection system. By using a specially designed pilot valve control room, the pressure change signals are compared, and the main valve opening signal is output to control the main valve opening, thereby controlling the inlet and outlet pressure difference of the main valve at the set value.

The 800X differential pressure bypass balance valve is a valve used to balance the pressure difference between the supply and return water of the air conditioning system. It can improve the utilization rate of the system, maintain the accurate and constant value of the pressure difference, and minimize the noise of the system and the damage caused to equipment by excessive pressure difference. The 800X pressure differential bypass balance valve is superior to other balance valves. It does not require other executing machinery and relies on the pressure difference of the medium itself to achieve system balance, saving energy and installation space.

The 800X differential pressure bypass balance valve utilizes hydraulic self control, without the need for other devices or energy sources, and is easy to maintain.

The 800X differential pressure bypass balance valve is widely used in water supply network systems such as high-rise buildings, living areas, and urban water supply projects.

Working principle of 800X differential pressure bypass balance valve:

When the pressure difference between the inlet and outlet of the main valve changes, the pressure difference between connecting pipe A and connecting pipe B changes. This pressure difference acts on both sides of the pilot valve diaphragm through the connecting pipe, changing the opening of the pilot valve. When the pressure difference is large, the opening of the pilot valve is large, and the amount of water discharged through the C pipe in the control room increases. The pressure in the control room of the main valve decreases, the opening of the main valve increases, and the pressure difference between the inlet and outlet of the main valve decreases. On the contrary, if the pressure difference between the inlet and outlet of the main valve decreases, the opening of the pilot valve decreases, and the pressure in the control room of the main valve increases, pushing the opening of the main valve to decrease and increasing the pressure difference of the main valve. This negative feedback effect stabilizes the pressure difference between the inlet and outlet of the main valve at the set value.
