Standard globe valve consist of valve body, bonnet, cage, seat and disc. The components of a globe valve are similar to gate valve. Globe valve usually have rising stem or outside screw and yoke construction. The valve stem must be turned many times to open and close the valve.
Globe valve are primarily used to regulate flow in pipeline and throttling application. The flow rate is control by the lift of the valve plug. Globe valve is able to operate in partially open position. When the valve is in partial open position it is less risk of getting the seat damage. Valve stem must not be turn too far because it could possible damage the seat surface.
Typically there are three types of globe valves: Tee Pattern, Angle Pattern and Wyre Pattern Globe Valve. Each design operated differently and depends on pressure and flow rate.
