Pressure Reducing Valve
Working principle: pressure reducing valve is through the adjustment, the inlet pressure will be reduced to a certain need for the outlet pressure, and rely on the medium’s own energy, so that the outlet pressure automatically maintain a stable valve. Proportional type is the use of the valve body within the piston at both ends of the cross-sectional area of the pressure difference, change the pressure after the valve to achieve the purpose of pressure reduction.
Scope of application: fire hydrant spigot overpressure; pressure reducing valve partition water supply; tandem decompression of the first stage.
Supplementary Note: Vertical installation is desirable.
Working principle: the opening of the opening and closing parts of the control valve body to regulate the flow of the medium to reduce the pressure of the medium, and at the same time, with the help of the pressure after the valve to regulate the opening of the opening and closing parts of the valve, so that the pressure after the valve to maintain a certain range of application.
Scope of application: overpressure of fire hydrant port; pressure reducing valve partition water supply more than 1.20MPa; tandem pressure reducing second stage, the valve before and after the pressure difference should be ≤ 0.40Mpa.
Supplementary note: Horizontal installation is appropriate.
Throttle valve
Working Principle: Throttle valve is a valve to control the fluid flow by changing the throttling cross-section or throttling length.
Scope of application: fire hydrant, alarm valve group.
Supplementary note: used to regulate the flow pressure, understand.
