HLV'S AP Series Rotary Pneumatic Actuators
AP series are piston operated valve actuators that use air pressure or natural gas to provide the force required to open, close and control rotating stem valves.
Performance Highlights
Our AP series actuator is perfect for rotary valves like ball valve, butterfly valve, etc.
Our AP series actuator is ideal for on/off or adjustment applications.
Our pneumatic actuators can accommodate a broad spectrum of valve applications from very high to very low thrust requirements.

Water Ingress Protected O-Rings are fitted on bodies, caps and so on, this ensure water ingress protected. The AP Series actuators interface meets ISO standard, and meets the dimensional requirements of ISO defined for each torque range.


The shaft driven accessory interface conforms to NAMUR and is identical on all AP Series models, allowing standardization of accessory mounting hardware and installation practices.

Wear Resistant
The guide rod and piston rod have an advanced surface treatment, which combined with self-lubricating bearings, provides superior wear resistance and extends the life of all sliding components.

High Efficiency

The piston rod and guide block connection superior surface finishes and self-lubricating bearings maximize input energy transfer directly to the valve stem, efficiency is further enhanced by the tension-loaded spring, minimizing radial loads on the piston rod.

Corrosion Resistant
The AP series actuators incorporate over three stages of internal and external coatings to resist severe weather, chemical and petroleum environments. The inner surface of cylinder is coated by PTFE, enhanced corrosion resistant and self-lubricating

Modular Design

AP series actuators have available, field serviceable drive, power, spring and override modules, the modules are removable, serviceable and interchangeable when mounted to the valve. Modules are available for separating purchase to reduce spare parts inventory

Safe Spring Module

To ensure the safety of personnel during installation and maintenance, the spring module has been designed so that it can only be removed from the power module with the spring in the fully extended position. This prevents accidental release of the spring force, protecting personnel from injury and the actuator from accidental damage.
