High pressure recovery valve


A valve structure, by the internal contour of the streamlined and minimum turbulence, it will spread to the relatively small amount of fluid energy. Accordingly, the flow cross-sectional view of the valve downstream pressure is reduced to a very high percentage of the value of the intake pressure to be restored. DC-type valve, such as a rotary valve is a typical recovery of high-pressure valves.3 way air valve
The inherent die pressure: atmospheric pressure in the valve body
The stroke of the piston pressure on the diaphragm to produce the high and low pressure. This is usually in the region of the spring range, because when the valve is disposed in the working area, this area is the movement of the valve.
The inherent flow characteristics: constant pressure flow and travel of the closure part the relationship between the nominal stroke of the valve from the closed position of the valve pressure drop.
Diaphragm pressure range: nominal stroke in the valve body of the high and low pressure to withstand the specified conditions, the role of the production of a film. Installed in the lamina propria of the pressure range, which may be in the closed components of the force from the diaphragm area.
After the installation of the traffic characteristics: the effect of the pressure drop through the valve through the process of change in the relationship between the nominal stroke of the closed position of the valve, flow and closure components.shut off solenoid valve
