About Globe Valves

Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service. Globe valves consist of the following moving parts – the disk, the valve stem, and the handwheel. The stem connects the handwheel and the disk. It is threaded and fits into the threads in the valve bonnet. The location of the valve disk in relation to the valve seat allows or restricts flow. The direction of fluid flow through the valve changes several times, which increases the pressure drop across the valve. In most cases, globe valves are installed with the stem vertical and the higher-pressure fluid stream connected to the pipe side above the disk, which helps to maintain a tight seal when the valve is fully closed.

Products & Services Related to Globe Valves

Air Pressure Regulators

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices.

Air Valves

Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.

Control Valves

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.

Diaphragm Valves

Diaphragm valves close by means of a flexible diaphragm attached to a compressor.

Plastic Valves

Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling.

Pressure Regulators

Pressure regulators are used to maintain a constant outlet pressure or flow.

Sanitary Valves

Sanitary valves are designed for applications requiring clean or sterile processing.
