Introduction

Handbook of Valves and Actuators

A mechanical device known as a valve actuator employs a power source to operate a valve. This power source may be hydraulic, pneumatic, or electrical (the flow of oil). For each of the two primary types of valves that use them, there are two different types of actuators. They are both linear and rotational.

The optimum actuator type for any application will rely on a number of variables, including:

Valve type
Power sources available
Environment of installation
Operational functions and characteristics

• need for fail safe

• cycle life

• duty cycle

• speed of actuation

• need for manual override

Valve Basic Interview Questions & Answers

Rotary Valve Actuators

Rotary valve actuators, as its name suggests, generate the rotational motion required to operate rotary valves including ball, plug, and butterfly valves. There are many various types of rotary actuators available, and each has advantages of its own.

Linear Valve Actuators

Due to their fundamentally different operations, linear valves including globe, gate, and pinch valves demand actuators that are very dissimilar from rotary actuators. To activate the valve, these actuators need to provide linear motion. They come in a variety of styles as well.
