800X Differential Pressure Balance Valve
Product overview
800X Differential pressure balance valve is a kind of valve used to balance the differential pressure between water supply and return water of air conditioning system. The valve can improve the utilization rate of the system, keep the accurate constant value of the pressure difference, and mi-nimize the noise of the system and the damage to the equipment caused by the excessive pressure difference. The advantage of 800X differential pressure balance valve over other balance valves lies in that it has no actuator, completely relies on the pressure difference of medium itself to achieve the function of balance system, saves energy and installation space, and is an intelligent valve.
Product Features
The normally closed differential pressure balance valve is used between the water supply and return pipes of fuel oil and gas heat sources, the water distributor and water collector of central air conditioner, as the bypass installation of variable flow system at the secondary side, which can effectively protect the oil and gas units from damage due to too high temperature caused by too small flow. The differential pressure balance valve can effectively protect the local freezing caused by the small flow of water chiller It will be damaged. Normally open differential pressure balance valve is used in central heating system with large height difference and heat source in high area. When used, the pressure difference of the valve is set according to the height difference, and a pressure reducing pump and check valve are installed at the appropriate position of the return water pipe in the low area. The return water pressure reducing device composed of the regulating valve can adjust and set the pressure of the return water pipe through the regulating valve, which can not only ensure that users in the high area will not empty, but also can Protect low area equipment from damage due to high pressure.
