Volume Booster is one-to-one Signal to output supply Air, when used with a positioner/actuator, itis a control device to increase the stroking speed of control valves.
The pneumatic Lock Up Valve series shuts off the signal pressure line either when the air supply falls below an adjusted value or upon complete air supply failure. This causes the actuator to remain in its last position.
Sizing example of NUTORK double acting actuator:
Valve torque 100Nm plus 20% safety factor= 120Nm. Minimum operating pressure 6bar(87psig). By reading down the 6bar(87psig) column the figure below 120Nm is 135.0Nm, The model number shown in the left hand column is therefore NKD-092.
