The HPAS Series Stainless Steel Pneumatic Actuator is powered by compressed air. Through the smooth linear movement of a dual piston rack, it drives the gear output shaft to control quarter-turn (angle stroke) valves. Available in both double-acting and single-acting (spring return) types, it is widely used for switching and regulating ball valves, butterfly valves, and plug valves. It is the perfect solution for modern industrial pipeline automation.

Key Product Features

1. Superior Corrosion Resistance

  • Made from premium stainless steel (ASTM 316L, 316, or 304) with an electro-polished finish.
  • Offers excellent protection against harsh chemicals, corrosive environments, and tough industrial atmospheres.
  • Features stainless steel fasteners for long-term durability.

2. High-Performance Rack & Pinion Design

  • The dual-piston rack and pinion design ensures a compact build, balanced mounting, long cycle life, and fast operation.
  • Fully machined gear teeth on the piston and pinion provide precise, low-backlash engagement for maximum efficiency.
  • Rotation direction can be easily reversed right in the field simply by inverting the pistons.

3. Smooth Operation & Safety

  • Multiple bearings and guides on the racks and pistons reduce friction, extend service life, and prevent shaft blowout.
  • Uses a modular, preloaded spring cartridge design with coated springs, ensuring high safety, excellent rust resistance, and versatile use.

4. Easy Adjustment & Standard Standards

  • Equipped with two independent external travel stop bolts that allow quick and precise adjustment of $\pm$5° in both open and closed positions.
  • Fully complies with international standards: ISO5211, DIN3337, and NAMUR, making it easy to interchange parts and mount solenoids, limit switches, and other accessories.

 

Mounting Standard

Air supply connection is designed in accordance
with the NAMUR Standard to install solenoid valves.
The Namur drive pinion and the Namur top mounting
connection permit direct installation of accessories
such as a limit switch box and a positioner.
Bottom mounting connection is designed in accordance
with ISO5211 and DIN3337 standards for direct mounting
with valve gear boxes or mounting brackets.
