What is a Globe Valve?

Two types of Kimray Globe Valves: the Back Pressure Regulator and the High Pressure Control Valve

Globe Valves

A globe valve is one of the most common types of control valve. Oil and gas producers use globe valves to control the flow, pressure and temperature of process fluid, water, or gas. In this article we will explain the function of a globe valve.

Globe valves have sphere-shaped bodies. Inside the valve, a baffle separates two halves.  This internal structure creates a different flow path than ball valves and other rotary-type valves. Globe valves actuate in a linear movement.

Oil and gas producers may control globe valves with mechanical, pneumatic, or electric power. Depending on the type, a globe valve can provide either on/off or throttling service.

Examples of globe valves include Kimray’s back pressure regulator and high pressure control valve.

Back Pressure Regulator

The Kimray Back Pressure Regulator is a type of globe valve designed to hold pressure on production vessels such as separators, treaters, and free water knockouts. When the valve reaches the predetermined set point, it releases that pressure upstream.

High Pressure Control Valve

The Kimray High Pressure Control Valve is a versatile type of globe valve that can be used in a variety of applications, including as a dump valve, pressure regulator, suction controller, and in plunger lift applications.

The valve remains in its fail position (open or close) a pilot tells it to actuate. In a liquid dump set up, for example, it will receive a signal from a liquid level controller to open and dump the liquid.

In a pressure regulating application, a pressure pilot monitors either upstream or downstream pressure, and when it needs to make an adjustment it sends a pneumatic signal to the valve actuator to open or close it.
