Description:
The valve is usually installed in the pipeline of water system from high-rise buildings, city water supply, fire fighting, mining, factories, pharmaceuticals and foodstuff, etc. When the pressure in the pipeline exceeds the setting one, this valve can reduce the inlet pressure to the certain outlet pressure automatically through the adjustment. And depending on the medium's own energy, this reducing valve can make the outlet pressure to be stable automatically. From the view of fluid mechanics, pressure reducing valve is a throttling component whose part resistance can change. The equipment can act as pressure holding valve to guarantee the water supply pressure from upstream of main valve. The operation of this reducing valve is stable and reliable. In addition, this pressure reducing valve features high quality, competitive price, easy installation, safety and so on.
Classification of Pressure Holding Valve:
Reducing valve is a kind of automatic valve. It is one of the regulator valves. According to the action principle, this valve can be classified into direct acting pressure reducing valve and pilot-operated relief valve. The bellow direct acting reducing valve can be applicable to low pressure steam medium with small or middle caliber. The film direct acting one can be used in middle or low pressure medium with small and medium size caliber, such as air, water, etc.
