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.
When globe valves are open, the fluid flows through the space between the edge of the disk and the seat. These valves are commonly used as a fully open or fully closed on/off valves, but they may be used for throttling as long as fine adjustments are not required.
These linear motion valves can be used in a variety of applications as long as the pressure and temperature limits are not exceeded, and the process does not require special materials to combat corrosion. Globe valves are generally available in a variety of metal and alloy constructions, as well as plastics, to cover this wide range of industrial applications. Proper material compatibility requires knowledge of the type, concentration and temperature of the media being handled. It may be necessary to consult the manufacturer of the valve for specific properties of the materials used in the valve.
Globe valves provide the following advantages: they offer precise throttling and control and have high-pressure limits. Conversely, they offer a low coefficient of flow and are not good selections in applications that require cleanliness or sterility.
Globe valves are available in three main body types (although custom designs are available as well): angle design, Y-design and multi-piece design. Angle valves are designed so that the inlet and outlet are perpendicular, for transferring flow from vertical to horizontal. Y-design valves derive linear action from the incline between the axis of the inlet and outlet ports. The bodies of multi-piece design valves are bolted together. The inlet and outlet are not of single piece construction.

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.
