1 Description
JAUDT double shuttle valves (DPK) are used for the infeed and outfeed of dust-like, fine and coarse bulk
goods which are fed to the double shuttle valve in pre-metered volumes.
JAUDT double shuttle valves are suitable for use under filters, separators, cyclones etc, as well as
outfeeding against a slight pressure difference to avoid a continual secondary air flow.
JAUDT double shuttle valves close in a product-tight manner and are robust and low-maintenance.
The dimensions must be designed sufficiently large to avoid product blockages.
Drive mechanisms for JAUDT double shuttle valves:
1. Electromotive actuation
2. Pneumatic actuation
3. Weight actuation
Functionality of electric-motor driven version with cam disc (Figure 1):
The opening and closing movement is controlled via an electric-motor driven cam disc (80). The closing
force is generated through balancing weights (110). The geometry of the cam disc defines and also
guarantees the overlapping of the two sealing discs (30) –that means that both valves are briefly closed
before one of the two sealing discs opens again. This ensures that both sealing discs are never open at the
same time.
The drive system is blockade-proof, as the transmission of power as the sealing disc opens is performed via
a direct-action slip clutch (drag handle). Once the slip clutch has been actuated, a status message can be
set using initiators.
The double shuttle valve can still continue to be operated even after the actuation of the slip clutch, but the
opening angle of the sealing discs diminishes.
The closing movement is also performed in an overload-proof manner thanks to the weight actuation.

5.1 Inspections and services of the JAUDT double shuttle valve
The inspection work must also be performed at the same time as the service work.
Check the JAUDT DPK for noise emissions,
Ensure that the motor and cylinder and the unit are running perfectly.
Caution! Danger of injury!
Ensure before starting work that the drive is switched off or disconnected. Make sure that the
system is switched off and secured against inadvertent activation before starting work. Inform
the control room. Only open the inspection apertures when the system and drive are
switched off.
Perform a visual inspection. Replace any damaged components.
Check that the bolts (especially the fixing of the gear motor and the motor bracket) , attachments and
fastening elements are tight.
Remove dirt and rust.
Check the shaft seals and adjust, or replace, the gaskets where necessary.
Check the interior for product encrustations and remove.
Check the valve and interior for wear and replace any worn components.
Check the cup springs on the valve lever every 3 months and repair any worn parts.
In the motor version, and for continuous operation, check the cam disc, roller and the bearing of the
roller every 3 months. Replace any worn parts.
Check that the drag handle is set correctly. The drag handle is set correctly if the valve opens fully and
the limit switches can be operated correctly.
In the event of an overload the drag handle will slip to prevent the mechanism being damaged. The limit
switches may then no longer be reached by the counterweight.
