What is Instrument Air Manifold ?
Instrument air manifold or air distribution manifold is a pipe shaped chamber (manifold) with several branches of outlets for delivering instrument air to multiple consumers such as control valve, actuated valve…
Control Valve Working Animation
Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers…
PID Controller Action : Directing Acting & Reverse Acting
Air to open/close valves and direction of control action Control valves come in two sorts: air to open; and air to close. Air to open valves are normally held closed by the…
Fundamentals of Valves and their Types
Valves are mechanical devices. They are basic elements with which the flow of fluids and pressure within a system can be regulated. They are mainly used to control the direction…
Types of Valve Actuators
Valve actuators are devices used to position valves. They can be used to fully open and shut a valve, or in an application that requires constant and precise control, such…

Valve Characteristics – Quick Opening, Linear & Equal Percentage
In essence a valve simply functions as a restriction in a flow line, with flow areas A1 and A2 and pressure differential p1 - p2, as shown in Below Figure. Valve Characteristics…
Short Notes on Different Valve Types
The essential function of a valve is to start, throttle and stop a fluid flow. Throttling, as shown in Below Figure, means regulating or controlling the rate of fluid flow. Different…
