The main application of 800X differential pressure bypass valve in the air conditioning system supply / return, ensure supply / return pressure difference between a fixed value, improve the utilization rate, reduce noise, and prevent excessive pressure damage of the system equipment. Hydraulic automatic control using this product, no other devices and energy, maintenance is simple, widely used in water supply system of high-rise buildings, living areas and city water supply engineering.
Product overview
■ 800X differential pressure bypass valve from the main valve, pressure control valve, needle valve, ball valve, micro-shaped filter and pressure gauge hydraulic control over the system. The control room through the pilot valve specially designed, according to the comparison of the change of pressure signal, the output of main valve opening signal, the main control valve opening, so as to control the main valve of the pressure difference between the inlet and outlet on the setting value.
■ 800X differential by-pass balancing valve is superior to other balance valve, it is not necessary to perform other machinery, completely rely on the media itself to achieve the function of the system pressure difference balance, energy saving and installation space.
