SMC Pressure Adjusting Valves for Vacuum
A vacuum pressure regulating valve is a pressure control device that adjusts air pressure and changes the flow rate to a pump. The pressure regulating valve is also called a pressure reducing valve or a regulator, and is attached to a vacuum line to control the pressure on the vacuum circuit side to a constant value. There are two types of vacuum pressure regulating valves: a vacuum regulator and an electric vacuum regulator that is controlled by an electric signal, and the pressure is displayed in analog or digital. There are two types of controls: direct acting and pilot-operated, and the pilot-operated type has an internal pilot and an external pilot. With direct acting, the valve is mechanically switched only with electric power, but the pilot uses the fluid pressure in addition to electric power. When making a selection, it is necessary to confirm the names of the piping screws on the supply and control sides, the diameter of the connection tube for installation, etc. Quick connect fitting elbows are available in addition to the standard type.
