Product Description

Y44H bellows pressure reducing valve Pressure reducing valve
The Y44H bellows pressure reducing valve is used to control the opening of the opening and closing parts in the valve body to adjust the flow rate of the medium, reduce the pressure of the medium, and adjust the opening and closing parts with the help of the role of the pressure after the valve, so that the pressure after the valve is kept in a certain range at the entrance
When the pressure is constantly changing, keep the outlet pressure within the set range, and protect the living production equipment after it. This type of valve in the pipeline should generally be installed horizontally.
Bellows pressure reducing valve is a necessary part of the pneumatic control valve, the main role is to reduce the pressure of the air source and stabilize to a fixed value, so that the control valve can obtain a stable air source power for regulating control.
According to the structural form can be divided into diaphragm type, spring film type, piston type, lever type and bellows type; According to the number of seats can be single seat type and double seat type; According to the different position of the valve disc can be divided into positive action type and reaction type
The work of Y44H bellows pressure reducing valve is controlled by the pressure behind the valve. When the pressure sensor detects that the valve pressure indication is increased, the opening of the pressure reducing valve decreases; When the pressure is reduced after the pressure reducing valve is detected, the opening of the pressure reducing valve increases to meet the control requirements.
Bellows pressure reducing valve - the valve's pressure reduction ratio must be higher than the system value to a certain extent; It should be able to respond to positive or negative control signals even at maximum or minimum flow. These valves should be selected for the useful control range, which is 20% to 80% of the maximum flow rate. Normally, they are of equal ratio type or have equal ratio characteristics. These types of valves themselves have the optimal flow characteristics and flow ranges required by proportional control.
There are many kinds of pressure reducing valves, common are: pilot piston pressure reducing valve, film pressure reducing valve, bellows pressure reducing valve, proportional pressure reducing valve, self-operated pressure reducing valve, direct acting piston pressure reducing valve, back pressure regulating valve and so on. They are suitable for different working media.
Different forms have different specific working principles. But the general principle is: the pressure reducing valve is through the throttle of the opening and closing parts, the inlet pressure is reduced to a certain required outlet pressure, and the outlet pressure remains stable. However, the general pressure reducing valve requires that the inlet and outlet pressure difference must be ≥0.2Mpa.
