Basics of Gate Valves

S Bharadwaj Reddy
The Gate valve is a linear actuating  valve used as flow isolater in a fluid pipeline.  As the name says the gate valve, a flat  circular or rectangular plate acts as...

Basics of Globe Valves

S Bharadwaj Reddy
Globe valves consist of a movable disk-type element and a stationary ring seat in a generally spherical body. The valve stem moves a globe plug relative to the valve seat....

Basics of Butterfly Valves

S Bharadwaj Reddy
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of...

Basics of Ball Valves

S Bharadwaj Reddy
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a “floating ball”) to control flow through it. It is open when the ball’s hole is...

Control Valves Theory

S Bharadwaj Reddy
The flow regulation  in a valve  is accomplished  by the varying  resistance as the valve  is stroked, i.e. its effective cross sectional area is changed. As the fluid moves from...

Control Valve Positioner Working Principle

S Bharadwaj Reddy
A Control Valve Positioner is a device used to increase or decrease the air load pressure driving the actuator until the valve’s stem reaches a “POSITION” balanced to the output SIGNAL from...

Self Actuated Pressure Control Valve Principle

S Bharadwaj Reddy
Self actuated pressure control valve do not depend on any external signal for pressure control. As the name suggests, pressure in the process line itself is used as an actuating signal...

Basics of Control Valves

S Bharadwaj Reddy
Valves are used for thousands of purposes, from simple and mundane tasks, such as turning on the water in a kitchen sink, to tasks as important and difficult as controlling...
