Description
The type 2405 pressure reducing valve is a kind of micro (differential) pressure regulating valve, which does not require external energy. It uses the energy of the controlled medium as the power source and drives the actuator to control the position of the plug to change the interception area, thereby changing the differential pressure and flow rate upstream and downstream, to achieve control stabilization for downstream pressure (control downstream pressure type) or relief pressure (control upstream pressure type). It has the advantages of sensitive action, excellent sealing, small pressure fluctuation, etc., and is widely used in the micro-pressure control of gases in various industrial equipment.
