Actuation and control for turbo machinery:
Modern turbo machinery needs to fulfill two basic prerequisites - optimum operation and low impact on the environment. Voith Electronic Drive Systems are active in the field of positioners and control for turbo machinery.
This comprises actuation for gas turbines, steam turbines and compressors, such as for example complete valve assemblies (valve with servo motor), servo motors or pilot controls designed as I/H-converters and way valves for existing positioners and the control system Turcon (turbine control) for steam turbines and compressors.

The VKD/CE is a True Union ball valve, electrically actuated, particularly suitable for industrial applications, where high performances and long time reliability are a must. The patented Seat Stop® system assures great longevity of the seals in situations where vibration or thermal expansion occurs. A micro-adjusting of the PTFE seals is also allowed. As any accidental loosening of the ball carrier is not possible, the radial dismounting of the valve body can be done in full safety. The new patented Dual Block® system allows a proper nut tightening, without any risk for unscrewing due to vibrations.

The actuator TA 130 Ex may be installed in areas with potentially explosive atmospheres consisting of gases and vapours with low ignition temperature and strong ignition penetration. The approval for operation in these areas is confirmed by the European ATEX Directive. Every possible electrical spark source is enclosed by a flameproof casing. For maximum corrosion resistance the TA 130 Ex is available in a stainless steel version. As an option the actuator can be made failsafe by mounting the spring return system TA-FM which opens or shuts the valve in an emergency without power supply.

Heavy Duty Double Acting Ball Valve Systems
Valve sizes from ¼” to 3”
140 in.lbs to 800 in.lbs
Spring Return Valve operators
Single acting with spring close or open
Valve Operator Systems
Spring Return operators are formed by bolting a spring return unit to a double acting Val-U-Act operator. The return movement is effected by a clock-type spring which is pretensioned to about half the operator torque. The amount of pretention is large, compared to the rotation and therefore the torque does not vary more than 20% over the rotation.
Spring returns are factory-installed and adjusted. The spring returns have a worm drive adjustment for setting or changing spring pretension. By inserting a socket key into one end of the worm the spring pretension can be very easily increased or decreased to suit operating conditions. To increase pretension, turn the worm clockwise; to decrease, turn counterclockwise.
