Type 8021 – Sliding gate valve
Sliding gate control valve with integrated positioner
GS3 series
This control valve is used in control circuits for neutral and aggressive media in the chemicals, process engineering and plant construction industries. Positioners (pneumatic or electro-pneumatic) are used for precise control. The valve is equipped with an integrated positioner (top-mounted) as standard.

High Pressure Control Valve with integrated positioner
GS4 series
Pneumatic control valve for the control of neutral and aggressive fluids at high operating pressures with integrated positioner
- Space saving screwed wafer type for flanges acc. to ANSI B16.5 construction
- Low weight in comparison to competitive valves
- Quiet operation
- High dynamic because of short stroke
- Control of high differential pressures with compact actuators
- Greatly reduced energy consumption rates due to short strokes and low actuating forces on the throttle element
- High Cvs-values
