Algas Spring Return Pneumatic Actuator

Scotch Yoke Design

Spring return pneumatic quarter-turn actuator for spring

end torques to 685,500 lb.in.

Features and benefits

• Scotch yoke design generates high break torque
needed for the actuation of many quarter-turn valves.
• Six bearings provide reliability, smooth operation
and extended service life:
- Two bronze yoke bearings ensure minimal friction.
- Two bronze sliding block bearings spread load
over large surface area.
- Guide block bearing and piston rod bearing of
sintered bronze impregnated with PTFE increase
efficiency, reduce maintenance and prolong
actuator life.
• Graphite-impregnated PTFE piston bearing reduces
friction between the piston and cylinder bore and
allows the cylinder to be operated without
lubrication.
• Guide bar supports the transverse forces and insures
proper support of the piston rod. Hard chrome
plating on guide bar provides corrosion resistance
and minimal friction loads.
• Chrome-plated piston rods provide maximum
corrosion resistance and minimal friction loads on
dynamic seals.
• Electroless nickel-plated cylinder bore provides
maximum corrosion resistance and reliability.
• Multiple external tie bar design provides maximum
cylinder integrity.
• Totally enclosed, weatherproof carbon steel housing
provides maximum strength. Internal coating
protects against corrosion.
• External travel stops allow precise adjustments of ±
4° rotation at each end of travel.
• Low hysteresis and high response enhance
modulating service.
• Spring cartridge incorporates up to four springs,
fully encapsulated in a tamper-proof factory welded
assembly.
• Spring configurations available up to 1,300,000
lb.in. spring end torque. Options and accessories Technical data
• Available with canted or with symmetric scotch yoke • Accessory mounting brackets provided for mounting Supply pressure : 20 to 150 psig

Notes
1. Maximum operating torque is maximum rating of scotch yoke mechanism.
2. Maximum allowable pressure is 150 psig (static pressure applicable to fully stroked actuator against travel stops).
3. Maximum operating pressure is the pressure required to produce the maximum operating torque of the actuator.

 Algas Spring Return Pneumatic Actuator
Scotch Yoke Design

Canted and Symmetric scotch yoke torque output

Algas actuators are available with either canted or symmetric scotch yoke mechanisms.
The canted versions produce a torque output as represented in Fig. 1 and Fig. 3 and are therefore most suitable for use with
valves which display a similar torque requirement, such as butterfly valves.

The torque output characteristics of the symmetric versions are as shown in Fig. 2 and Fig. 4 and are most suitable for use
with valves which display a similar torque requirement, such as ball valves.
