Linear Actuators

Linear actuators generate linear motion to operate valves in various industrial applications and, are available in numerous styles. They convert energy into linear motion, allowing for precise control of gate, globe, and diaphragm valves. Pneumatic actuators, commonly used for these valve types, utilise compressed air to drive the upward and downward movement of the rising stem. Diaphragm and cylinder styles are popular options for efficient and precise linear control.

Key Benefits of Linear Actuators:

• Accurate Positioning: Linear actuators ensure precise control over valve movement.
• Reliability: They are known for their durability and consistent performance.
• Efficiency: Pneumatic actuators offer efficient operation with minimal energy consumption.

Popular Linear Actuator Options at ESI:

• Saunders S360 Pneumatic Diaphragm Actuator – The S360 provides reliable performance, high cycle life, lower air consumption and a more compact design versus diaphragm-type actuators.
• Saunders P345 Pneumatic Diaphragm Actuator – The P345 operates on a lower pressure (4.5 bar) compared to traditional models. This innovative design translates to significant CO2 emission reductions while also minimizing your energy costs.

Types of Linear Actuators:

• Pneumatic Linear Actuators:
  • Diaphragm: Uses a flexible diaphragm to convert pneumatic pressure into linear motion.
  • Rack & Pinion: Converts rotational motion from a motor or handwheel into linear motion using a rack (linear gear) and a pinion (rotary gear). Available in single-acting and double-acting configurations.
• Electric Rotary Actuators: Convert electricity into kinetic energy for precise rotational control.

Applications for Pneumatic Actuators:

• Oil & Gas
• Food & Beverage
• Chemical Processing
• Wastewater Treatment
• Pharmaceutical
• Power Generation and more
