How Needle Valve Works ?
Needle valves are designed to allow precise flow control. Its name is derived from the sharp pointed disc and matching seat. They are extensively used for continuous blow-off or chemical
Solenoid Valves Practical Problems
Suppose this valve control system has a problem. The control valve (LV-104) does not move to the full-open position as it should when the solenoid is de-energized, although it will

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
