Brief introduction of precision pressure reducing valve products

Precision pressure reducing valve is an essential part of pneumatic control valve, its main function is to reduce and stabilize the air pressure at a fixed value, so that the control valve can obtain stable air power for adjustment and control.

According to the structural form, it can be divided into diaphragm type, spring diaphragm type, piston type, lever type and bellows type; According to the number of valve seats, it can be manual single-seat and double-seat type; According to the position of intervertebral disc, it can be divided into active type and reactive type.

The work of precision pressure reducing valve is controlled by the pressure behind the valve. When the pressure sensor detects that the valve pressure indicates an increase, the valve opening of the pressure reducing valve decreases; When the pressure drop after the pressure reducing valve is detected, the valve opening of the pressure reducing valve is increased to meet the control requirements.

Precision pressure reducing valve-the pressure reducing ratio of this valve is 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 according to the useful control range, that is, 20% to 80% of the maximum flow. Normal is proportional or has proportional characteristics. These types of valves have the best flow characteristics and flow range required for proportional control.
