The Festo VZXA Series Angle Seat Valve is an externally actuated valve controlled by a direct supply of compressed air, used to shut off gaseous or liquid media in pipe systems. In the process, a spindle with a soft-sealing valve disc is raised and lowered using a pneumatic actuator. The valve seat is slanted at an angle of approximately 40° in relation to the medium flow. The flow direction is determined by the design of the valve (angle seat fitting and actuator).

Two flow directions for the valve are available. "Closing in the direction of medium flow" is used for gaseous media only, while "closing against the direction of medium flow" is used for gaseous and liquid media in order to prevent or reduce water hammer.
