Brass flange pressure reducing valve

Brass flange pressure reducing valve

Flange pressure reducing valve from the general thread of the pressure reducing valve, its connection flange, this is a control valve in the body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, under the condition of the inlet pressure changing, keep the outlet pressure within the scope of the set, protection appliances for production from then on.

An overview of the:

Flanged pressure reducing valve, piston type pressure reducing valve, steam pressure reducing valve is a necessary parts of the pneumatic control valve, the main role is to decompress the pressure of the air source and stabilize to a fixed value, so that the control valve can obtain stable air source power for regulation and control.

According to the structure can be divided into diaphragm type, spring film type, piston type, lever type and bellows type;According to the number of valve seats can be single seat type and double seat type;According to the position of the valve disc can be divided into positive and reaction type

The work of the flange pressure reducing valve is controlled by the pressure after the valve.When the pressure sensor detects that the pressure of the valve is increased, the valve opening of the pressure reducing valve decreases;When the pressure of the pressure reducing valve is detected, the valve opening of the pressure reducing valve is increased to meet the control requirements.

Flanged pressure reducing valve -- the valve's pressure reduction ratio must be higher than the system value to some extent;It should be able to respond to positive or reactive control signals even at maximum or minimum flow rates.These valves should be selected for a useful control range of 20 to 80 percent of the maximum flow.Normal is of geometric type or has geometric characteristics.These types of valves themselves have optimal flow characteristics and flow ranges required for proportional control.

There are many kinds of pressure reducing valves, common are: pilot piston type pressure reducing valve, film type pressure reducing valve, bellows type pressure reducing valve, proportional type pressure reducing valve, self type pressure reducing valve, direct action piston type 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 still: 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 to maintain stability.But the general pressure reducing valve is required to import and export pressure difference must be greater than 0.2Mpa.
