Product Description:

A program-controlled valve is a shut-off valve driven by pneumatic, hydraulic, or other means. The valve is connected to the DCS distributed control system or PLC to achieve remote control of computer programs. Widely used in pressure swing adsorption gas separation industries such as methanol cracking for hydrogen production, alcohol drying, vinyl chloride concentration and recovery, polycrystalline silicon tail gas recovery, nitrogen production, oxygen production, and carbon dioxide recovery. The program-controlled valve is a key equipment of the pressure swing adsorption device and an important component to ensure the smooth completion of various processes and reliable operation of the system. The main processes of pressure swing adsorption include adsorption, pressure equalization, forward release, reverse release, flushing, etc. The completion of each process is achieved through the opening and closing of a programmable valve for a certain period of time. The program-controlled valve is an important component for the pressure swing adsorption device to complete its process, and it is also a key equipment for the device to achieve normal operation and reliable work.
