Valves Manufactured by Liberty Industries
They are basically pipe fittings that are used to stop or regulate or direct or divert or control the flow of fluids like liquids, gas, fluidized solids and slurries. Fluids flow from a higher pressure zone to a lower pressure zone. Valves are an inevitable part of our life. We need valves for a regular water supply to launch a rocket in space. Valves can be operated manually using a handle, lever, wheel or even a pedal. Or they can be automated using change in pressure, flow or temperature. More complex automated valves use an actuator that uses an external input and set-up. We will cover few types of valves that are manufactured by Liberty Industries in this article. So that you can select the one which you require and also it helps to end all your confusions. We provide knowledge regarding various types of valves through this simple yet interested article. Even if you are not a technical person, still you are able to understand the flow of this content. Globe Valves Globe valve is used to regulate flow in a pipeline. Generally it has a spherical body, and is separated into two parts by internal baffle. It has an opening where a moveable disc is screwed in to close the valve. The disc is connected to a threaded stem that can be connected to a hand wheel in manual valves and can be used to close or open the valve. Automated globe valves use a smooth stem and the valves are closed and opened by an actuator assembly. Gate Valves Gate Valve is also known as Sluice Valve. You can open it by lifting a round or rectangular gate out of the pipe. The sealing surface between the gate and seat are planar. And that's why they are widely used when minimum restriction and straight flow of fluids are preferred. For e.g.: Gate Valves are used in petroleum industries, where some of the liquids have very high viscosity. It is designed to fully open or fully close functions as the partial flow may increase the chances of vibration of gate and subsequent leakage. Ball Valves Ball Valve has a spherical disc that has a hole/port in the middle. When the port is in line with both ends of the valve, fluid flows through the hole. When the port is perpendicular to both ends of valves, flow is blocked. They are used in shut off process as the work effectively even after long time of disuse. Hence Ball Valves are preferred over globe valves and gate valves.
