Abstract

A control valve including a valve body, a chamber arranged inside the valve body, a fluid inlet, a fluid outlet, and a closing arrangement for regulating the flow of fluid from the fluid inlet to the fluid outlet via the chamber. The closing arrangement has a closed state in which no fluid, or only a leakage flow, is allowed to flow through the chamber, a first open state in which fluid is allowed to flow through the chamber, and at least one second open state in which a lower flow of fluid is allowed to flow through the chamber compared to when the closing arrangement is in its first open state. Between the closed state and the second open state, the closing arrangement is configured to allow fluid to flow through the chamber in accordance with a first valve characteristic function.

Dependent claims

A control valve comprising:

a valve body, a chamber arranged inside said valve body, a fluid inlet for providing fluid to said chamber, and a fluid outlet for receiving fluid from said chamber, and a closing arrangement for regulating the flow of fluid from said fluid inlet to said fluid outlet via said chamber,
said closing arrangement having a closed state in which no fluid, or only a leakage flow, is allowed to flow through said chamber, a first open state in which fluid is allowed to flow through said chamber, and at least one second open state in which a lower flow of fluid is allowed to flow through said chamber compared to when said closing arrangement is in its first open state,
wherein
between said closed state and said second open state, said closing arrangement is configured to allow fluid to flow through said chamber in accordance with a first valve characteristic function, and
between said second open state and said first open state, said closing arrangement is configured to allow fluid to flow through said chamber in accordance with a second valve characteristic function being different compared to said first valve characteristic function.
