How it works

Spring-return rotary actuator

Spring-return rotary actuator: Air supplied
Air suppliedAir turns the shaft against the springs.
Spring-return rotary actuator: Air removed
Air removedThe springs return the shaft to its rest position.

Butterfly disc

Butterfly disc: Closed
ClosedThe disc stands across the bore.
Butterfly disc: Open
OpenThe disc turns into line with the flow.

5/2 double-solenoid pilot

5/2 double-solenoid pilot: Coil 14 pulse
Coil 14 pulseSupply 1 feeds port 4; port 2 exhausts through 3.
5/2 double-solenoid pilot: Coil 12 pulse
Coil 12 pulseSupply 1 feeds port 2; port 4 exhausts through 5.
5/2 double-solenoid pilot: Both coils off
Both coils offThe spool keeps its last position; the drawing retains the coil-14 example.

Limit-switch box

ClosedThe closed-position contact is made.
Limit-switch box: Open
OpenThe open-position contact is made.

The number that matters

Nominal pressure

16bar

The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

Applications

Media and industries

  • Air
  • Steam
  • Oils
  • Fuels
  • Greases
  • Animal Fats
  • Water Supply
  • Heating

Rotary disc gate valve is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Operating principle: The valves are opened and closed by turning the disc by 90°. Opening is performed by turning the handle anti-clockwise, closing - clockwise.
DNOVA pneumatic double-acting rotary actuators PA-DA and pneumatic rotary actuators with return spring PA-SA are designed for automation of industrial valve control with maximum torque up to 2128 Nm.
The pneumatic valve is used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
