The Norbro actuator is recognised
as the leading name in the quarter turn pneumatic actuator
market. Designed for high performance and reliability
using the unique guide rod design, the Flowserve Norbro
can be used in a wide range of applications.
The actuator is also designed for
safety and ease of maintenance using features such as
anti-blow out pinion and long end cap screws to release
spring energy.
Features:
Unique
guide rod design for long life
Double
acting and spring return in same body size
Anti-blow
out pinion
Namur (VDI/VDE)
solenoid and top mounting
ISO mounting
platform
Large size
range
With
eleven sizes in the range the torque outut can be closely
matched to the required valve torque to provide a competive
actuated package
Designed for the control of batch/filling
operations, the P61 provides rapid, repeatable and highly
accurate control in both level of weigh measuring processes
The valve uses the basic spring return
Norbo with additional pistons allowing the actuator
to be adjusted to a semi closed position for trickle
flow before finally closing the filling valve. This
stage is manually adjustable and therfore highly repeatable
Available in 7 sizes from the Norbro
range with DIN ISO 3337 mounting platform.
Automax Supernova series Rack
and Pinion actuators are designed for butterfly, plug,
or ball valves, and offer one compact design for double
acting and spring return. Precision die-cast pistons
with large cylinder bearings increases efficiencey and
cycle life. The actuators incorporate a precision-extruded
hard anodized aluminium body and a one piece nitride
coated or nickel-plated pinion gear, factory lubricated
for a long trouble-free life.
The actuators are designed for 100
degree travel with clockwise and counterclockwise travel
adjustment for open and closed positions up to Size
200. Available in torque ranges from 8 Nm to 5,005 Nm,
for optimum actuator sizing.
Features:
Field reversible
action simply by rotating pistons 180 deg
One compact
design for double acting and spring return is easily
field convertible by installing or removing springs
Broad size
range offers optimum actuator sizing for each valve
requirement
Corrosion
resistant, hard anodised aluminium housings with stainless
steel fasteners
The R2, R3 and R4, Series Scotch Yoke
heavy-duty actuators provide torques from 1,000 to 17,000
in-lbs. The combination of Scotch Yoke actuators, Rack
and Pinion actuators, plus Automax's extensive range
of automation products offers the opportunity to standardize
on one source for your complete quarter-turn automation
needs. The R Series actuators can also be configured
with high pressure hydraulic cylinders.
The R5 Series heavy duty scotch yoke
actuator provides torque output as high as 500,000 in
lbs. Piston rods are guided and supported by self lubricating
bronze bearings. The slot in the R5 scotch yoke mechanism
is precision machined. The yoke pin is is induction
hardened and chrome plated. It is supported at the top
and bottom by a guide in the slot in the housing and
the yoke pin rollers are hardened steel
Features:
Pneumatic,
hydraulic and Gas models
Double
Acting, Spring Return and 'Fail Safe' configutrations
are available
On-Off,
Multi-position, throttling, Fast closing
Pressure
ranges from 40 psi to 2500 psi
Overrides,
Positioners, Limit Switches, control valves and conditioners
available
The VL spring cylinder linear
actuator is a powerful, high-performance pneumatic actuator
that provides positive throttling or on-off operation
for automatic control valves. Most cylinder sizes are
designed for supply pressures up to 150 psi (10.3 Bar).
Using a spring to provide failsafe operation, this actuator
is completely field reversible for air-to-open or air-to-close
operation without additional parts. The positioner supplies
air to both sides of the piston, providing stiff, precise
movement and high-frequency response.
Our in house engineering facility
allows us to offer our clients a wide range of locally
manufactured mounting kits to fit any valve, actuator
and accessory combination. Our standard material for
manufacture is stainlesssteel
ensuring protection against the corrosive environments
that exist at the coast and on most chemical plants.
