Does the 4v230c08 solenoid valve maintain pressure?

Did not keep the pressure. The 4v230c08 solenoid valve is just a gas path control element, which can't bear high pressure. If it is necessary to maintain the pressure in the gas path, it is necessary to use other gas control elements with pressure maintaining function, such as pneumatic diaphragm pump and pneumatic liquid pump. 4v230c08 solenoid valve has no pressure maintaining function. The 4v230c08 solenoid valve is usually an ordinary pneumatic valve with fast electromagnetic control. It can control various pneumatic devices by controlling the solenoid valve to adjust the switch and direction of the gas path.
