FEATURES AND BENEFITS

• Innovative stainless steel construction provides superior internal and

external corrosion resistance.

• Scotch yoke design using precision bearings eliminates dead band in

the yoke mechanism, providing the greatest torque output at the

beginning and end of stroke.

• High strength 17-4PH stainless output shaft transmits torque and gives

long service life.

• Heat-treated stainless steel thrust pin androllers transfer piston force

to yoke to reduce friction for longer life and more efficient torque

transmission.

• Bi-directional travel stops provide accurate valve rotation adjustment.

• PTFE piston bearings, piston rod bushings and output shaft bushings

provide longer life, reduce maintenance and require no lubrication.

• Universal design position indicator and pointer allows for either parallel

or perpendicular mounting.

• Stainless steel construction allows proximity switches to be direct-mounted

in the actuator housing, eliminating the need to mount bracket and cam

assemblies on top.

• NAMUR drive slot maintains a compact assembly for accessory-driven

components with no couplings necessary.

• Available in symmetrical and canted yoke design to suit application.

• Spring return model design requires no special tools to disarm springs

safely and easily, reducing down time.

Stainless steel spring return and double acting pneumatic quarter-turn actuators

Output torques to 240.000 lb.in.

Checks Upon Actuator Receipt

• Check that the model, the serial number of the actuator and the technical

data reported on the identification plate correspond with those of order

confirmation (Section 1.2).

• Check that the actuator is equipped with the fittings as provided for by

order confirmation.

• Check that the actuator was not damaged during transportation: if necessary

renovate the painting according to the specification reported on the

order confirmation.

• If the actuator is received already assembled with the valve, its settings have

already been made at the factory.

• If the actuator is delivered separately from the valve, it is necessary to check,

and, if required, to adjust, the settings of the mechanical stops (Section 3.6)

and of microswitches (if any) (Section 3.7).

Introducing the Actuator

ALGA actuators were engineered and manufactured to provide maximum torque

output with minimum supply pressure. ALGA actuators are suitable for the operation

of any quarter-turn operation like ball, plug, butterfly valves or dampers, in both

on/off and modulating heavy-duty service.

The actuator (Figure 4) is made up of a weatherproof scotch yoke mechanism

transforming the linear movement of the pneumatic cylinder (on closing or opening)

into the rotary movement, which is necessary for operation. The angular stroke of

the yoke is adjustable between 82° and 98° by means of the external mechanical

stops screwed into the left wall of the mechanism housing and into the end flange

of the pneumatic cylinder. The cover of the scotch yoke mechanism is arranged

for the assembly of the required accessories (positioner, signaling limit switches,

position transducer, etc.) by means of proper matching units. The above-mentioned

accessories are operated by the actuator drive sleeve. The housing of the scotch yoke

mechanism has a flange with threaded holes to fix the actuator to the valve either

directly or, if required, with the interposition of an adaptor flange or a mounting

bracket. The actuator yoke has a hole with keyways suitable for the assembly of an

insert bush the internal hole of which is machined (by Biffi or at customer’s care),

according to the shape and dimensions of the valve stem. Biffi can supply different

types of control system following  the customer’s requirements.

Description

Bently Nevada™Scout™COMMTEST220 and COMMTEST240 are

portable data analyzer solutions designed to monitor machinery

in non-hazardous environments. These small form-factor,

rugged devices take vibration recordings and upload the

collected data for detailed analysis in System 1.

This is a two-part solution. The COMMTEST data acquisition

module uses Bluetooth to communicate with awireless,

industrial handheld device running the S1 Collector app.

Vibration recordings are viewed and stored on the handheld

device.The handheld runs the Android OSor Apple iOS, so you

canalso useit like any smartphone or tablet to take pictures and

video, send text messages, check email, make phone calls, track

your location, create SOS alerts, and run other enterprise apps.

The high performancedata acquisition module(HardwareID:

109M2380) provides long battery life, yet is light & rugged. It

hangsout-of-the-way on ashoulderstrap, allowing you to focus

onyourjobandmovesafelybetweenmachines.

The COMMTEST220 can sample two sens or channels

simultaneously, while theCOMMTEST240supports up to four

channels. Both also support tachometer or Keyphasor triggering.

These dataacquisition modules provides up to ten hours of

continuous use, while supporting an Fmax up to 80 kHz and12.800

lines of spectral resolution.

The System 1 software, paired withCOMMTEST220and

COMMTEST240.enablesyoutotrackall of your machinery using

asingle enterprise monitoring system. Use System 1 to prepare

routes, analyze data, detect long-term trends, and set and
