800X Differential Pressure Bypass ValveIt is a valve used to balance the differential pressure between supply/return water of an air conditioning system. The valve meets the utilization of the system, keeps the differential pressure constant and reduces the noise of the system as well as the damage to the equipment caused by excessive differential pressure. 800X differential pressure bypass valve is more suitable for the air conditioning system than other valves.balancing valveThe place is that it does not have an actuator, relying on the medium's own pressure difference to achieve the function of balancing the system, saving energy and installation space, is a kind of intelligent valve.
Structural features and applications
800X differential pressure bypass valve consists of a main valve, differential pressure control pilot valve,needle valve,ball valvespolymorphicfilterand pressure gauge to form a hydraulic control receiver system. Through the designed pilot valve control chamber, it compares the pressure change signal and outputs the main valve opening signal to control the main valve opening, so as to control the main valve's inlet and outlet pressure difference at the set value. This product utilizes hydraulic self-control, does not require other devices and energy, easy maintenance. This series of valve products for high-rise buildings, living quarters and other water supply network systems and urban water supply projects.
