Valve Actuators:

A few categories of actuator are essential to permit for the positioning of a valve. Actuators vary from easy manual handwheels to associatively complex electrical and hydraulic manipulators.

Introduction

Valve actuators are selected based upon a number of factors including torque necessary to operate the valve and the required for automatic actuation. Categories of actuators involve manual handwheel, electrical motor, manual lever, hydraulic piston, pneumatic, solenoid, and self-actuated. Whole actuators except manual handwheel and lever are adaptable to automatic actuation.
