800X differential pressure bypass valve

800X differential pressure bypass valve is a valve used for air conditioning system to balance the pressure difference between the supply and return water. 800X pressure difference bypass valve from the main valve, pressure difference control guide valve, needle valve, ball valve, micro shaped filter and pressure gauge hydraulic control over the system. Through the design of the pilot valve control chamber, the pressure change signal for comparison, the output of the main valve opening signal, control the main valve opening, so as to control the main valve inlet and outlet pressure on the set value. The working principle is that when the main valve inlet and outlet pressure difference between the A and take over the pressure difference between the B, the opening of the valve. Large differential pressure pilot valve opening degree of the control room through the C tube water discharge increases, the main valve pressure drop in the control room, the main valve opening increases, the main valve import and export pressure difference becomes small. On the contrary, if the main valve inlet and outlet pressure difference, the valve opening is small, the main valve control chamber pressure rise, the main valve opening to reduce and make the main valve pressure difference. The negative feedback function of the main valve and the pressure difference between the inlet and outlet is stable on the top of the club. Set the needle valve opening and pilot valve spring pressure can be set to the main valve pressure difference between import and export.

The valve can improve the utilization of the system, maintain the accuracy of the pressure difference, and can maximize the noise of the system, as well as the excessive pressure caused by damage to the equipment. 800X differential pressure balance valve is superior to other balance valve is that it does not implement the mechanism, complete the media's own pressure difference to achieve the function of the balance system, save energy and installation space, is an intelligent valve.
