The work of the CNG Regulator is controlled by the pressure behind the valve. When the pressure sensor detects that the valve pressure indication increases, 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 increases to meet the control requirements.
The pressure reduction ratio of the CNG Regulator valve 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 the maximum or minimum flow. These valves should be selected for the user control range, that is, 20% to 80% of the maximum flow. Normally, it is equal or has an equal ratio. These types of valves have the best flow characteristics and flow ranges required for proportional control. This type of valve should generally be installed horizontally in the pipeline.
The types of CNG Regulator include pilot piston pressure reducing valves, membrane pressure reducing valves, bellows pressure reducing valves, proportional pressure reducing valves, self-operating pressure reducing valves, direct-acting piston pressure reducing valves, back pressure regulating valves, etc. Wait. They are suitable for different working media.
There are also many types of CNG LPG ECU .
