Vacuum Flow Control Valve

The flow control valve is often a butterfly design.

Vacuum flow control valve.

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. The evr is a non relieving regulator intended for processes where at least a very small gas flow is present at all times. 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. If your process is gas tight an equilibar.

Downstream pressure control valves are used downstream of the vacuum chamber to throttle the gas flow exiting the system. When choosing the right valve for a vacuum application several factors should be considered such as. 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. Mks is the established leader in downstream pressure control subsystems which integrate exhaust throttle valves advanced digital controllers and baratron process manometers.

Here air pressure must applied and must be controlled by switching the control valve with its control voltage often 24 v dc. Get it as soon as thu oct 1. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Equilibar evr is a direct vacuum regulator.

The vacuum valve in different versions pfeiffer vacuum vacuum valves are used in wide ranging solutions in industrial applications and research areas. If there is an electromagnetic control valve for the inlet and outlet of the compressed air directly on the pneumatic drive head there is an electro pneumatic drive. 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.
