Operating instructions
4.3 Intended application
The gate valves are one-sided sealing valves
that shut off the media in the flow direction.
The gate valve is closed or opened by turning
the handwheel.
Gate valves with an actuator are driven by a
compressed air supply, e.g. via an 8,0 mm
hose, with a recommended working pressure
of 6,0 bar, max. 10,0 bar. The gate valve is
opened by the supply air and closed by the
spring. A reverse mode of operation is not
possible.
Emergency actuation:
The gate valve is opened by 30.0 mm by
turning the 27 mm adjusting screw directly
above the actuator in the counter clockwise
direction; turning it clockwise closes the gate
valve.
NOTICE! Tools for increasing handwheel
torque are not allowed.
