Frequently Ask Questions

What Is a Cage Guided Pneumatic Actuated Control Valve?

A Cage Guided Pneumatic Actuated Control Valve is a globe-type control valve in which the valve plug is guided by a cage surrounding the plug. A pneumatic actuator moves the plug linearly to regulate process flow.

Who Is a Cage Guided Pneumatic Actuated Control Valve Manufacturer in India?

Alis Valves manufactures and supplies Cage Guided Pneumatic Actuated Control Valves for high-pressure and severe-service applications, including oil & gas, refineries, petrochemical plants, power generation, steam, chemical processing and industrial automation.

What Is the Difference Between Cage Guided and Double Seated Control Valve?

A cage-guided valve primarily describes how the plug is guided and how the trim is constructed, while double-seated refers to a valve having two seating surfaces. A cage-guided valve may be single-port or have other specialized trim arrangements.

What Is the Purpose of the Cage?

The cage provides stable and accurate plug guidance. It helps reduce lateral movement, vibration and instability, particularly under demanding flow conditions.

Is a Positioner Required?

For precise modulating control, a positioner is recommended. It improves positioning accuracy and repeatability.
