An inherently equal % characteristics control valve operating under such condition will behave like a linear valve and an inherently linear characteristics control valve will behave like a quick-opening control valve.

Oct 20, 2022 · Linear valves are the most popular type of valves available today. Their ease of use and simple design have made them extremely common. These valves, also referred to as multi-turn valves, use a sliding-stem design to control the position of a closure element.

Flowserve's linear control valves product portfolio is one of the most comprehensive in the flow control industry. Explore a wide range of linear control valves today.

Comparing linear and equal percentage valves, a linear valve might have a 25% valve opening for a certain pressure drop and flowrate, whilst an equal percentage valve might have a 65% valve opening for exactly the same conditions.

LINEAR CONTROL VALVES. The linear-style valve is the most common type of valve available today. It is well-known for its simple design and ease of maintenance. Linear valves, also known as multi-turn valves, have a sliding-stem design that pushes a closure element into an open or closed position.

The majority of control applications are with valves with linear, equal-percentage, or modified-flow characteristics. Installed Control Valve Flow Characteristics. When valves are installed with pumps, piping and fittings, and other process equipment, the pressure drop across the valve will vary as the plug moves through its travel.

The FlowTop control valve is a high-performance, general application valve coupled with the high-thrust FlowAct pneumatic diaphragm actuator. The modular design allows you to use the same body with different types of bonnets, trims and actuators.

The Valtek Mark One globe control valve offers superior performance in liquid and gaseous services, while also permitting easy, fast and inexpensive maintenance. The spring-cylinder actuated Mark One valve provides stiffness and maintains high positioning accuracy, repeatability, controlled high speed, and faithful response.

Linear control valves are designed to offer precise control over the rate of fluid flow by linearly positioning the valve stem, disk, or plug. This linear movement correlates directly with the flow rate, providing the operator with accurate control.

A linear control valve is a type of linear valve specifically designed for precise control of process variables, such as flow rate, pressure, or temperature. They typically feature a characterized trim and a positioner for accurate and repeatable positioning of the closure element.
