1.Applications
This kind of valve is applied in the water supply and delivery system, which can quickly reflect the pressure fluctuation and quickly release the pressure, preventing the damage of the pipeline and equipment resulting from the sharp increase of pressure. Especially, the valve is suited for decompression of the fire control system of high-rise buildings, and it can secure the water supply pressure in the upper reaches of the main valve.


2.Characteristics
a. Precisely keep the safe and stable pressure. In case of overpressure, the decompression valve can fully open and decompress in time.
b. Adjustable cut-off speed, eliminating fluctuation of the pressure.
c. The transmission mechanism of the diaphragm minimize the phenomenon of the operation lag.
d. The valve can be installed anywhere, and it doesn't need to change the setting value of pressure. After it removes from the pipeline, the repair and check can be applied at once.


3.Technical parameters
a. Nominal pressure: 1.0MPa,1.6MPa,2.5MPa,4.0MPa
b. Outlet pressure: PN1.0MPa Adjustment range: 0.30.9MPa

                              PN4.0MPa Adjustment range: 1.03.5Mpa
c. Engaging pressure: 0.05Mpa
d. Applicable medium: clean water
e. Applicable temperature: 080
