MORIN B C scotch yoke actuators

For remote control of any quarter-turn application: ball, butterfly,
rotary plug or damper style valves, etc. for use in chemical
process, food and beverage, iron and steel, pharmaceutical, power,
oil and gas, pulp and paper and textile industries.

• B series - Ductile iron with stainless steel cylinders

• C series - Ductile iron with carbon steel cylinders

• Spring return and double acting actuators Quarter-turn output
torques to 158200 Nm

Biffi ALGA ALGAS pneumatic scotch yoke actuators

suitable for quarter-turn valves up to the largest sizes,
thanks to an efficient design and to high break-out torque.
The QA version with damper performs fail strokingin less than
1 second.

• Design pressure: 12 bar g (174 psi)

• Double acting torque: up to 750,000 Nm (6,630,000 Lb in)

• Spring ending torque: up to 235,000 Nm (2,078,000 Lb in)

Biffi RPD RPS rack & pinion actuators

offer a reliable, easy and cost effective solution, providing
maximum torque output with minimum supply pressure.
The housing can be ductile iron or carbon steel; all other parts
are in carbon steel as a minimum.

• Design pressure: 12 bar g (174 psi)

• Double acting torque: up to 3.700 Nm (32,700 Lb in)

• Spring ending torque: up to 1.100 Nm (9,700 Lb in)

Biffi PLA PLAS linear actuators

Double acting and spring return pneumatic linear valve actuators
for on-off and regulating service.

• Design pressure: 12 bar g (174 psi)

• Double acting thrust: up to 1,600,000 N (359,000 Lb)

• Spring ending thrust: up to 555,000 N (124,800 Lb)

Biffi TPD TPS linear actuators

Helical spline design

Compact quarter-turn pneumatic actuators for on-off and
modulating control of ball, butterfly, plug or damper style valves
in heavy duty service. Generating output torques up to 300,000 Nm,
it is the ideal solution where space is limited.

Designed with a unique helical slot design, which transforms the
linear movement of a piston into a quarter-turn rotation, generating
high break torques to actuate large valves. With its spring integrated
into the cylinder, it is very compact with the same dimensions
whether for double-acting or spring return; spring to open or spring
to close operations

Biffi FCBB and FCBA pneumatic scotch yoke actuators

are compact, lightweight, and economical scotch-yoke design
actuators providing optimum torque curves for quarter-turn operation.
FCBB, with standard dual valve mounting interface, provides
flexibility for installation in a fail-open or fail-close application without
the need of actuator disassembly. The housing can be ductile iron or,
if requested, with the carbon steel option.

• Design pressure: from 9.3 to 13.8 barg (142 psi to 200 psi)

• Double acting torque: up to 2492 Nm (7,388 Lb in)

• Spring ending torque: up to 1182 Nm (22,055 Lb in)
