Summary:
The water-using pressure reducing valve made in our company is used in various building's water supply system, fire-fighting system, central air-conditioning system and warming systems. It is used for the pressure reduction of branch pipes so as to have the water supply pressure distributed more reasonably, to avoid over-pressure of partial water supply and optimize the water supply of high buildings. And it can replace the frequency-adjusting speed variable water pump of the quarters and the water pump of the quarters in the fire-fighting water supply system. When it is used in the household water supply system, it can protect all tape halters and other water utensils.
Features:
a. Using a directly acting membrane structure, with very simple internal structure, without jamming reliable performance and durable. b. Dirt-resisting and water filth preventing, no need of the filter and the by-pass pipe, very simple pipe-fitting which saves a great deal of space and pipe-fitting cost. c. Adjusting outlet pressure precisely, which is not influenced by the inlet one, in general conditions (the variable of the output pressure is 8% of Δ P1). d. Extremely good hydraulic performance, small pressure loss, the pressure reducing ratio can be up to over 10:1. e. Capable of satisfying multiple pressures reducing requirements, especially suitable for the branch-pipe pressure reducing system.
