Control Functions and Flow Direction

Flow Direction Below the Seat

Only use flow direction below the seat for liquid media, gases, and vapors. As the medium is present under the swivel plate, the operating pressure contributes to the opening of the valve.

Flow Direction Above the Seat

Only use flow direction above the seat for gases and vapors, and for valves with control function A (closed by spring force in rest position). As the medium is present above the swivel plate, the operating pressure contributes to the closing of the valve. The operating pressure also supports the sealing of the valve seat.

DANGER

WARNING! Risk of damage due to bursting pipes and bursting equipment when the flow is above the seat. In the case of liquid mediums, water hammer can occur causing pipes and the device to burst. Do not use valves with flow above the seat for liquid mediums.
