Self-Contained Low-Power EH Actuators (HL2)

Surface Actuation

Master Flo HL2-Series actuators are engineered for robust, long-lasting performance. These low-maintenance, double-acting piston actuators operate with standard hydraulic pressure supply and include fail-safe capability. Equipped with an advanced, multi-option automatic positioning system, these actuators provide precise control.

Customizable for Your Needs

HL2-Series actuators come with matched hydraulic supply and thrust requirements. You can choose from additional options such as manual hand pump overrides, adjustable travel stops, and special materials. Furthermore, positioners can be selected to meet various hazardous-area certification requirements.

Key Features:

Reliability: Rugged construction with minimal moving parts ensures a long service life with low maintenance.
Interchangeability: Actuator yokes incorporate standard industry mounting bosses, allowing for universal interchangeability.
Protective Coatings: External surfaces are powder coated for maximum protection against harsh environments, and special coatings like offshore epoxy are also available.
Instrument Mounting: Equipped with an advanced, low-power positioning system with incremental stepping and fail-safe capabilities.
