Vacuum Flow Control Valve

Mks is the established leader in downstream pressure control subsystems which integrate exhaust throttle valves advanced digital controllers and baratron process manometers.

Vacuum flow control valve.

The evr directly controls vacuum pressure by throttling flow between the vacuum supply pump and the process in order to precisely control the process vacuum to a specific setpoint. Equilibar evr is a direct vacuum regulator. Often used to extend and then retract a cylinder at different speeds they create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Manual and stepper motor controlled valve options are available for up stream pressure control.

Solenoid valves for vacuum applications. Here air pressure must applied and must be controlled by switching the control valve with its control voltage often 24 v dc.

When choosing the right valve for a vacuum application several factors should be considered such as. Downstream pressure control valves are used downstream of the vacuum chamber to throttle the gas flow exiting the system. The problem with this arrangement is that the control loop is often too slow to allow the vacuum pressure to remain at setpoint when there are changes to the flow rate coming into or out of the system. Vacuum pressure p vac measured relative to atmospheric pressure.

Bakeable leak valves are used to control the flow of gas into a vacuum system from an external source. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. The flow control valve is often a butterfly design. The evr is a non relieving regulator intended for processes where at least a very small gas flow is present at all times.

Circuit function 2 way 3 way etc flow rate kv value design principle direct semi direct. In order to meet these requirements as fully as possible the vacuum valves are divided according to size type of flange and drive and according to the pressure range used. 4 6 out of 5 stars 19. The vacuum valve in different versions pfeiffer vacuum vacuum valves are used in wide ranging solutions in industrial applications and research areas.

If your process is gas tight an equilibar.
