Single Acting Pneumatic Actuator Gallery
Every LORZEN Single Acting Pneumatic Actuator has gone through highly controlled conditions to ensure the high quality of your Pneumatic Actuators.
Description
Single acting pneumatic actuators utilize air pressure to provide a unidirectional stroke for operating quarter-turn valves. With a compact and lightweight design, they are an economical solution optimized for on-off applications across various industries. The spring-return mechanism allows reliable valve control in case of air supply failure.
Available in aluminum and stainless steel bodies with NPT threaded air connections, these actuators offer durability in most environments. Their adjustable cam allows easy modification of stroke length to suit different valves.
Our single acting actuators feature a 360° visual position indicator and adjustable travel stops for precise valve control. Please contact us to select the optimal size and configuration to suit your specification requirements.

LORZEN Pneumatic Actuators Are Utilized Across Various Sectors, Including:
Actuator Design
Single Acting Pneumatic Actuator Selection
Under normal operating conditions. a safety factor of 20% - 30% is considered for double acting actuators
Example:
Valve torque= 100Nm
Safety torque- 100(1+ 30%) = 130Nm
Air source pressure=5Bar
Compared with the double-acting torque table, the specification of the optional Double-acting actuator is DA105.

Single Acting Pneumatic Actuator Working Principle
Double acting actuator
CCW(Standard)
lnlet A, compressed air pushes the piston outward,causing the actuator output shaft to rotatecounterclockwise (0 →90 ) and the B port is vented.lnlet at port B,compressed air pushes the piston Moveinward to rotate the output shaft of the actuatorclockwise (9o °→0 °), A port row.
CW
lnlet A,compressed air pushes the piston outward,causing the actuator output shaft to rotates clockwise(9o °→o ) and the B port is vented. Inlet at port B,compressed air pushes the piston Move inward torotate the output shaft of the actuator rotatescounterclockwise (0 °→90 °), A port row.
Single acting actuator
FC-CCW(Standard)
lnlet A, compressed air overcomes spring force,pushes the piston outward，and the actuator Outputshaft rotates counterclockwise (o。 → 90 )，B portexhausts: actuator loses air, piston Under the action ofthe spring force, it moves inward and the actuatoroutput shaft rotates clockwise (90 °→0 °), exhaustat port A.
FO-CW
lnlet air from port A, compressed air overcomes springforce and pushes the piston outward.The output shaftof the actuator rotates clockwise (90 ° o °), and port Bexhausts; The actuator loses air, and the piston movesinward under the action of spring force. The outputshaft of the actuator rotates counterclockwise (o ° 90), exhaust at port A.
