Overview:

A Globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flow-path or it can completely close the flow-path. Conventional Globe valves may be used for isolation and throttling services. Although these valves exhibit slightly higher pressure drops than straight=through valves (e.g.gate, plug, ball, etc.), they may be used where the pressure drops through the valves is not a controlling factor. Globe valves are extensively employed to control flow. The range of flow control, pressure drop, and duty must be considered in the design of the valve to avert premature failure and to assure satisfactory service. Valves subjected to high differential pressure throttling service require specially designed valve trim. Generally, the maximum differential pressure across the valve disc should not exceed 20 percent of the maximum upstream pressure or 200 psi (1380kpa), whichever is less. Valves with special trim may be designed for applications exceeding these differential pressure limits.

Applications of about Globe Valves

Gate valve is a quick opening and closing valve.It is used as on-off valve and valve for controlling flow or for throttling the working fluid.
