Air/Hydraulic Actuators

Versative, high-performance air/hydraulic actuators are designed to take advantage of available pressurized air sources to produce high hydraulic pressures. Ideal for brake applications in the construction, material handling, mining, forestry and farming industries as well as many other industrial applications.

Air/Hydraulic Actuator

Master Cylinder with Air Chamber

Our master cylinder type air/hydraulic actuator is the combination of a conventional master cylinder and an air chamber. The master cylinder is a single acting type with one piston. 

Air pressure is used to actuate a push rod in the air chamber. The push rod in turn moves the piston in the master cylinder which forces the hydraulic fluid into the system.

Available with or without internal residual check valve

Incorporates a conventional master cylinder

Available for industrial and mobile applications

Sealed diaphragm fluid reservoir

Air/Hydraulic Actuator

Straight Bore Master Cylinder with Air Chamber

This air/hydraulic actuator is similar to those found above. This model however, uses a larger straight bore master cylinder for more displacement and a larger air chamber for more pressure. Like the previous model, air pressure is used to actuate a push rod in the air chamber. In turn, the push rod moves the master cylinder piston which forces hydraulic fluid into the system.

 

Available with or without internal residual check valve

Incorporates a conventional master cylinder

Available for industrial and mobile applications

Air/Hydraulic Actuator

Stem Seal Master Cylinder with Air Chamber

These air/hydraulic actuators are a combination of a fluid actuator and an air chamber. They are designed to take advantage of available pressurized air sources to product hydraulic pressure. The stem seal actuator eliminates cup cutting by allowing the cups to move freely in the master cylinder without passing over any ports.

Available for industrial and mobile applications using hydraulic oil or brake fluid

Includes stroke indicator

Internal valving design enhances bleeding process and extends normal service life of primary seal

Air/Hydraulic Actuator

Stem Seal Actuator with Air Chamber

Our straight bore actuator type air/hydraulic actuator is the combination of a remote actuator and an air chamber. The remote actuator has a single acting piston with a stem seal. The stem seal actuator eliminates cup cutting by allowing the cups to move freely in the master cylinder without passing over any ports.

Allows towed vehicle's brakes to be controlled from brake pedal of towing vehicle

Ideal for spring brakes - cup seals never pass over ports

Available for industrial and mobile applications
