What is meant by throttling in valves?

A: Throttling valves are a type of valve that can be used to start, stop and regulate the flow of fluid through a rotodynamic pump. When the flow of a pump is regulated using a throttling valve, the system curve is changed. The operating point moves to the left on the Pump curve when the flow is decreased.

What is throttling in pipeline?

Gas throttling is reduction of pressure in a gas flow forced through a throttle – local hydrodynamic resistance point (orifice choke, valve, tap, check), accompanied by temperature change. Throttling can cause frosting of locking, regulating and metering devices, as well as forming of gas hydrates in pipelines.

What is meant by throttle and throttle valve?

: a valve designed to regulate the supply of a fluid (as steam or gas and air) to an engine and operated by a handwheel, a lever, or automatically by a governor especially : the valve in an internal-combustion engine incorporated in or just outside the carburetor and controlling the volume of vaporized fuel charge …

How does throttling affect flow?

A throttling valve restricts the cross sectional area through which the fluid flows increasing supply or upstream pressure and reducing flow resulting in a decrease in pressure and flow on the unrestricted or down stream branch of the system. Diffential pressure flow meters use this principal to measure flow.

What valve is best for throttling?

butterfly valve
Among the most common valves, the butterfly valve is the most suitable for throttling. A full quarter turn can open or close the valve.

What throttled means?

1a(1) : to compress the throat of : choke. (2) : to kill by such action. b : to prevent or check expression or activity of : suppress policies that throttle creativity. c US, informal : to defeat easily or completely The Jets went to Miami and throttled the Dolphins.—

What happens during throttling?

Throttling is a process where a high-pressure fluid is converted into low-pressure by using a throttle valve. In a throttling process, the enthalpy remains constant and the work done is zero.
