Pressure regulation and control of closed containers
This pressure controller integrates two solenoid valves: an inlet valve introduces process gas into the chamber, maintaining pressure in the sealed space; when the pressure is too high, the pressure relief valve automatically opens to relieve pressure, quickly and accurately controlling pressure stability while avoiding gas waste.
It also features a pressure sensor and a digital circuit board, providing high-precision, fast, stable, and reliable pressure control. This PC digital board has all the functions needed to control pressure. In addition to the standard RS485 output signal, it also provides analog input/output signals, allowing precise control of the entire process by adjusting the setpoint. The touch screen makes operation more convenient.
Furthermore, it can be equipped with an integrated control valve or a separate control valve. It is a proportional electromagnetic control valve with ultra-fast and smooth control characteristics. We have different series of control valves for specific applications. Standard direct-acting valves are used for general applications, pilot valves for high flow rate applications, and dual valves for pressure regulation and relief applications.
