A Hydraulic gear pump immersed in its own reservoir delivers pressurized oil to the vane-type 90° actuator via the control box, which contains non-return valves and solenoid valves to direct the flow into the actuator; with cam operated limit switches to control travel and (optionally) signal position to the user. The unpressurised side of the actuator is connected to the reservoir, so there is no net transfer of oil from reservoir to actuator. The pump and its motor run entirely on precision ball bearings, so that the friction and motor size can be minimized and life maximized; the efficiency resulting from this reduces the heating effect and allows 100% rating. A pressure release valve is built into the pump so that if the actuator load becomes jammed the torque is limited and dangerous over pressures or motor stalls are avoided.

Kinetrol HD 1/4 Turn Electric Actuator
1. EHD 1/4 Turn Electric Actuator
®
An electronic circuit and a feedback potentiometer are fitted
inside the standard actuator control box. The circuit is a high
stability linear comparator, which switches the actuator pump
and solenoid valves via solid state mains switches in
response to the difference between the actual position
measured by the potentiometer and the intended position
given by the 4-20mA signal. Limit switches prevent the
actuator driving against its own endstop, whatever the signal
may be.
The positioner mains switches are optically isolated from the
low voltage DC control circuit, which is electrically isolated
from the rest of the actuator.
The feedback potentiometer is a conductive plastic servo-type
unit driven by a backlash-free drive. The positioner circuit is
mounted inside an insulating polymer box for safety; it is fitted
with screwdriver adjustable potentiometers to allow customer
turning of zero, gain and dead band width.
The efficient design of the Kinetrol EHD actuator allows a
high start frequency to be achieved, without overheating. The
positioner is available on fail-safe spring-return and
double-acting units, and gives accurate, linear low hysteresis
performance with excellent thermal stability. The intrinsic
stiffness of the hydraulic system together with the
backlash-free design of the Kinetrol vane actuator makes this
positioner very tolerant of varying or unstable loads
(eg . butterfly valves). The complete absence of separately
mounted enclosures makes installation neat, simple and
economical - all external connections for power, signal and
limit switches are made to the normal connector block in the
control box.

2. PUMP MOTOR - Brushless, runs on ball bearings for unlimited maintenance
free life. AC types are single phase capacitor induction motors, with
self-resetting cut-out for over temperature protection. DC type is brushless with
integral drive circuitry.
A Hydraulic gear pump immersed in its own reservoir delivers pressurised oil to the vane-type 90° actuator via the control
box, which contains non-return valves and solenoid valves to direct the flow into the actuator; with cam operated limit
switches to control travel and (optionally) signal position to the user. The unpressurised side of the actuator is connected to
the reservoir, so there is no net transfer of oil from reservoir to actuator. The pump and its motor run entirely on precision ball
bearings, so that the friction and motor size can be minimised and life maximised; the efficiency resulting from this reduces
the heating effect and allows 100% rating. A pressure release valve is built into the pump so that if the actuator load becomes
jammed the torque is limited and dangerous over pressures or motor stalls are avoided.
Fail-safe spring return action uses a reliable
low-stress-range sealed clock-type spring unit
mounted coaxially with the actuator, together with
a fail-open solenoid valve, to ensure reliable
positioning when power is not supplied to the unit.
A high flow external dump valve can be fitted to
allow very rapid spring-driven action (to be wired
by customer - contact Kinetrol for details).
Double-acting models are supplied with
solenoids arranged to give position locking when
power is disconnected. An optional manual by-
pass valve is available to allow manual override
movement of a double acting when power is
disconnected.
OPTIONAL ANGLE ADAPTOR PLATES - Allows mounting of motor-pump
assembly within 15 degrees of vertical whatever the angle at which the actuator
output shaft is mounted. (Not needed if output shaft is vertical or horizontal).
MULTI-POSITION PUMP MOUNTING INTERFACE - Allows motor to always be
above oil reservoir, so that motor shaft seal is never pressurised by oil and motor
always remains free of oil.
OIL PUMP WITH INTEGRAL RESERVOIR - Efficient low friction gear pump
runs on ball bearings for minimum wear, maximum life. Enclosure integrates
pressure release valve to prevent harmful overpressure build up. Uses silicone
oil for minimal effect of temperature on performance.

The interface between pump/reservoir unit and the control box allows mounting
of the pump in different orientations at 90° to each other, so that the motor can
be kept above the reservoir whether the actuator output axis is horizontal or
vertical. External electrical connections are all made via a single accessible
connector block in the control box, with the simplest possible switching needed
to drive the unit. Two conduit entries are available, to allow easy separate
connection of power and signal lines (if used). All internal wiring is connected
via a central connector and fuse board, and the actuator is protected from
supply surges by a metal oxide varistor suppressor.

The interface between pump/reservoir unit and the control box allows mounting
of the pump in different orientations at 90° to each other, so that the motor can
be kept above the reservoir whether the actuator output axis is horizontal or
vertical. External electrical connections are all made via a single accessible
connector block in the control box, with the simplest possible switching needed
to drive the unit. Two conduit entries are available, to allow easy separate
connection of power and signal lines (if used). All internal wiring is connected
via a central connector and fuse board, and the actuator is protected from
supply surges by a metal oxide varistor suppressor.

5. EHD 1/4 Turn Electric Actuator
®
An electronic circuit and a feedback potentiometer are fitted
inside the standard actuator control box. The circuit is a high
stability linear comparator, which switches the actuator pump
and solenoid valves via solid state mains switches in
response to the difference between the actual position
measured by the potentiometer and the intended position
given by the 4-20mA signal. Limit switches prevent the
actuator driving against its own endstop, whatever the signal
may be.
The positioner mains switches are optically isolated from the
low voltage DC control circuit, which is electrically isolated
from the rest of the actuator.
The feedback potentiometer is a conductive plastic servo-type
unit driven by a backlash-free drive. The positioner circuit is
mounted inside an insulating polymer box for safety; it is fitted
with screwdriver adjustable potentiometers to allow customer
turning of zero, gain and dead band width.
The efficient design of the Kinetrol EHD actuator allows a
high start frequency to be achieved, without overheating. The
positioner is available on fail-safe spring-return and
double-acting units, and gives accurate, linear low hysteresis
performance with excellent thermal stability. The intrinsic
stiffness of the hydraulic system together with the
backlash-free design of the Kinetrol vane actuator makes this
positioner very tolerant of varying or unstable loads
(eg . butterfly valves). The complete absence of separately
mounted enclosures makes installation neat, simple and
economical - all external connections for power, signal and
limit switches are made to the normal connector block in the
control box.
