Video 1: BHN 601 01 block and vent valve
The BHN 601 01 is an intermediate flange valve that can be used to pneumatically isolate the actuator from the control valve and to vent the actuator.
Video 2: DRN flow regulator plates
With our DRN flow regulator plates, the speed of single- and double-acting actuators can be controlled very precisely. Thanks to a slotted spindle, the flow regulator plates can be adjusted with exceptional precision.
Video 3: HVRZN hand lever valve
The HVRZN 731 702 is a flange-mounted valve that can be used to override a positioner or another control valve. This allows the actuator to be operated manually via the hand lever. The process valve can be opened, closed, or held in intermediate positions.
