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)
