actuator torque
3 in-depth engineering guides on actuator torque — specification, selection, testing and procurement.
Everything on actuator torque
Vajra's engineering team has published 3 technical guides covering actuator torque for industrial valve selection, specification, testing and procurement. Browse the full set below.
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.
How to Specify a Butterfly Valve - Face-to-Face, Disc, Lining, and Actuator
Butterfly valves are the most diverse valve type - they range from inexpensive rubber-lined wafer valves for water service to large-bore triple-offset metal-seated valves for refinery and pipeline duty. Getting the specification right requires understanding the offset geometry, seat type, end connection, disc material, and actuator torque. This guide walks through every specification parameter.
