5 in-depth engineering guides on pneumatic actuator — specification, selection, testing and procurement.
Everything on pneumatic actuator
Vajra's engineering team has published 5 technical guides covering pneumatic actuator for industrial valve selection, specification, testing and procurement. Browse the full set below.
Butterfly Valve Actuator Torque Sizing - Breakaway, Running, and Seating Torque
Incorrect actuator torque sizing causes valve failures - too small and the valve won't open; too large and it damages the valve stem. This guide explains all torque components and sizing factors.
Electric vs Pneumatic Valve Actuator: Which Should You Choose?
Electric and pneumatic valve actuators are both widely used, but they have fundamentally different strengths. Pneumatics are fast and inherently fail-safe; electric actuators offer precision positioning and independence from instrument air supply.
Valve Actuator Selection - Pneumatic vs Electric vs Hydraulic
The right actuator converts available power into precise valve movement while meeting fail-safe, speed, torque, and environmental requirements. Pneumatic actuators dominate process plants; electric actuators are growing in remote and ATEX locations; hydraulic actuators handle the largest torque requirements. This guide compares all three and explains how to select for your application.
Valve Actuator Sizing: How to Calculate Breakaway Torque and Choose Pneumatic vs Electric
Selecting the wrong actuator - undersized torque, wrong fail-safe direction, or wrong actuator type - is one of the leading causes of valve automation failures. This guide covers the complete actuator sizing process: torque calculation, pneumatic vs electric selection, safety factor application, and fail-safe specification.
Industrial Valve Actuators: Pneumatic, Electric and Hydraulic Selection Guide
Selecting the right actuator type for an automated valve is as critical as selecting the valve itself. Pneumatic, electric, and hydraulic actuators each have distinct characteristics, advantages, and limitations that make them suitable for different process environments and control requirements.
