Pilot operated overflow cartridge valve RPIC-LAN engineering machinery parts

    Flow control valve is a valve design, development, manufacturing of a new product, also known as 400X flow control valve, is a high-precision pilot way to control the flow of multi-function valve. It is suitable for the distribution pipe to control the flow and pressure of the pipeline, keep the predetermined flow unchanged, limit the excessive flow to a predetermined value, and appropriately reduce the upstream high pressure, even if the upstream pressure of the main valve changes, it will not affect the downstream flow of the main valve. So how does the flow control valve work?
The structure of digital display flow control valve is composed of automatic spool, manual spool and display part. The display part is composed of flow valve movement, sensor transmitter and electronic calculator display part.
Its work is extremely complex. The measured water flows through the valve, the water flows into the impeller in the flow movement, the impeller rotates and the sensor transmitter induction, so that the sensor sends out the telecommunication number proportional to the flow, the telecommunication number is sent through the wire into the electronic calculator, after the calculator calculation, the microprocessor processing, the flow value is displayed.
The manual spool is used to regulate the flow rate and set the required flow value according to the displayed value. The automatic spool is used to maintain a constant flow rate, that is, when the pipe network pressure changes, the automatic spool will automatically open the fire and close the small valve port under the action of pressure to maintain the set flow value.
