Actuators

Features

• Diaphragm Actuators: Use a flexible diaphragm to convert air pressure into mechanical motion; provide smooth and precise control, ideal for fine-regulation applications; lower maximum force compared to piston actuators but offer fast response and low maintenance; constructed from corrosion-resistant materials suitable for demanding environments; operate at air pressures up to 12 bar and tolerate a wide temperature range; preferred for applications requiring precision and delicate control.
• Piston Actuators: Designed for applications requiring high force and fast response; operate with compressed air for linear or rotary motion, with double-acting or spring-return options; robust construction in carbon steel or stainless steel, resistant to corrosion and high pressures (up to 12 bar); wide operational temperature range, typically -60 °C to 160 °C; compatible with accessories such as positioners, solenoid valves, and travel limiters; ideal for large valves or severe services that require greater force.

Design

• Diaphragm Actuators: Flexible diaphragm transmits air pressure to generate smooth, precise linear motion; compact, lightweight, and easy to maintain, with quiet operation; incorporate spring-return or double-acting mechanisms to meet various operational needs.
• Piston Actuators: Robust steel or aluminum bodies convert air pressure into linear or rotary motion via pistons; designed to withstand high pressures and severe conditions, with double-acting and spring-return options; prepared for integration with accessories such as positioners and solenoid valves, facilitating automation in complex industrial applications.

Applications

• Industrial Automation: Essential for automation in oil, gas, and petrochemical industries.
• Valve Control: Fundamental for valve operation in power generation and chemical plants.
• Flow and Pressure Regulation: Used in water treatment systems for precise flow and pressure control.
• Precision vs. Force: Diaphragm actuators for high precision, piston actuators for applications requiring high force.

Construction Materials

• Diaphragm Actuators: Body made of carbon steel with anti-corrosion coating, aluminum, or stainless steel depending on model and application; diaphragm made from flexible, durable materials such as fiber-reinforced rubber or special elastomers; internal components in stainless steel or carbon steel treated for wear and corrosion resistance; seals and gaskets in EPDM, Viton, or similar materials, selected for media compatibility.
• Piston Actuators: Body and covers in carbon steel (A105) or stainless steel (304, 316), with optional anti-corrosion coatings; pistons made from anodized aluminum or stainless steel for high wear resistance; seals and packing in PTFE, expanded graphite, or specific elastomers for high pressure and temperature; internal components designed for durability in severe services, with corrosion- and erosion-resistant materials.
