Geared
Manual Overrides
Kinetrol
declutchable geared overrides are available for
models 05, 07, 09, 10, 12, 14 and 16, rated for
the same torques as the actuators and fitted
between the actuator and the load.
The standard unit is supplied with the right hand
handwheel option (see drawing below), whereby when
the handwheel is moved in a clockwise direction
the actuator moves in a counter clockwise
direction. A left hand handwheel option is also
available.

Manual
Failsafe Spring Units
If you want to operate a valve manually, but
maintain the advantage of the failsafe springs
certainty of position when unattended, use this
device.
- Manual unit
cannot be left in the wrong position
- Reliable torque
delivery for valve reseat
- Fire fail-safe
option for fail-safe manual operation of
valves etc.
- Clockwise or
counter clockwise 90° spring action (02
version reversible without the need for spring
removal)
- Weatherproof
sealed spring housing to protect from internal
corrosion
Application
The manual fail-safe spring units are available in
Kinetrol sizes 02, 03, 05 and 07 with factory
adjusted torques from 1.4Nm to 45.5Nm. Models 05,
09 and 12 fire fail-safe units (maximum torque to
260Nm/2300lbf.ins) are available. |

Spring
Failsafe Electric Actuators (EHD)
Kinetrol's
electrohydraulic actuator is designed for use in
areas without compressed air. A hydraulic pump
delivers pressurised oil to a Kinetrol
quarter-turn actuator, providing torque outputs up
to 1220 Nm/10800 lbf.in. On power failure a
Kinetrol spring return and fail-open solenoid
valve produce a positive fail-safe action. A
pressure release valve and 100% rated pump motor
provide stall protection. This together with the
unit's capacity for 3000 starts per hour make it
ideal for high cycle double acting and modulating
applications. |

Solenoid
Valves
As an option
KINETROL actuators sizes 03 to 14 can be supplied

tubing is necessary.
Standard optional solenoid valves can be
converted to 5 or 3 port versions by changing the
valve body plate supplied with the unit.
- Coil voltages:
AC: 50/60 Hz 24, 115 & 230 volts DC: 24
volts. For other voltages contact Kinetrol
- Electrical
connection: DIN 43650 plug with Pg9 cable
gland (6 to 8mm dia) as standard
- Manual override:
Extra to order
- Exhaust
silencers/flow regulators: Extra to order

reliability of the Kinetrol Vane actuator with a
ruggedly designed gearbox, the new Damper Drive
will beat anything on the market today when it
comes to control accuracy and cycle life. For more
information call Kinetrol USA.

I/P
Controller
The optional
Kinetrol I/P Controller is mounted in
place of the standard diaphragm housing on the
side of the positioner case. The positioner can
still be mounted in any attitude and gives an angular
output position which is proportional to the input
current control signal between 4 and 20 milliamps.
The 420 mA signal is converted to an air
pressure by a coil and magnet and flapper valve
arrangement. This air pressure controls the
positioner in the normal way. Air supply to the
unit is taken from the same constant 80 psi/5.5
bar supply as the positioner, no pressure
reduction required.
Zero and range adjustment is done within the
positioner in the same way as with a standard
pneumatic positioner. No adjustment is necessary within the I/P Controller. The cover is removed
only to connect the two wires - this is not
necessary with the DIN plug option. |
