800X pressure balance valve bypass valve plant selection Hangzhou Tiandun "800X pressure balance valve bypass overview" 800X pressure bypass balancing valve is used for an air conditioning system, in order to balance the pressure difference between the backwater valve. Pressure bypass valve can improve the utilization of the system, keep each other fixed straight precise differential pressure, and minimize system noise, too much pressure and damage to equipment caused. 200X pressure balance valve actuator is superior in that it does not fully own the medium to achieve the function of the differential pressure balancing system, saving energy and installation space, is an intelligent balance valve valve in other places. "800X pressure bypass balancing valve performance characteristics," one, two ends of the constant pressure valves and controlled system, allowing users to run the system with variable flow. 2, relying on automatic work without outside pressure force. 3, can be displayed directly control the pressure. 4, can be set to control pressure. 5, the control pressure regulating sensitive, simple operation. 6, the medium temperature: 0 ~ 150 ℃. 7, the control pressure adjustable range: 0.05 ~ 0.6Mpa 8, control pressure error ≤ ± 5%. "The main purpose of balancing valves 800X pressure bypass" normally closed bypass pressure control valve for oil, gas heat supply and return pipe between the central air-conditioning points, catchment, as a determination of the flow, the secondary side installing variable flow bypass system, which can effectively protect the fuel temperature gas-fired units will not be too small due to the high traffic and damage, which can effectively protect the local traffic due to the freezing cold water unit is too small and caused damage. Normally open pressure control valve is used to bypass the height difference is large and the heat source in the upper zone of the central heating system, when used properly installed according to the height difference between the position of the set pressure of the pressure valve and return pipe in the lower zone pumps, check valves, pressure regulating valve device consisting of backwater, by adjusting the valve to adjust and set the return pipe pressure, so the user can ensure the high zone emptied phenomenon does not occur, but also to protect the lower area of ??the equipment does not damage due to excessive pressure.
