Globe valves are used to regulate flow by a moveable plug and stationary seat which separate two internal chambers. The plug can be screwed in to close the valve against the seat. Globe valves are used for applications where throttling or repeated operation is required. They can provide fine control of flow and are the most common type of valve to use for modulating flow.
The three basic globe valve body designs are Wye, Tee and Angle. All of which are commonly used to throttle, open or close flow in a system. Globe valves offer good shutoff capability, moderate to good valve throttling capability and shorter stroke when compared to a gate valve. They are easy to machine or resurface the seats and can also be used as a stop-check valve.

Valsteam Actuated Globe Valves, also known in the industry as Control Valves, are suitable for controlling the pressure, temperature, level and humidity of a wide range of media. They are commonly used in steam applications and can be used to allow precise control thanks to the large surface area of their diaphragm style actuators.
Valsteam ADCA’s PV25 On-Off valves are single seated, two-way body constructed with in-line straight connections. The PA pneumatic actuator features a rubber diaphragm and multi-springs, and its action can be DA-direct action (air to close) or RA-reverse action (air to open). Their wide application range allows these valves to be used with the most common process fluids, including water, superheated water, steam, air, gas and other non-corrosive fluids. Choose from either a single seated, two-way, direct or reverse action valve.
Having been established for over 40 years in the United Kingdom and Ireland, Bürkert have worked hard to develop and build an experienced premier and partner distribution network. BM Engineering Supplies and Bürkert have a long established distributer partnership, which means you do not have to look far to source Bürkert’s cutting edge merchandise. As such, we are able to supply Bürkert’s full range of pneumatically operated globe valves.
Bürkert’s Type 2012 2/2–way Globe Valve consists of a pneumatically operated piston actuator and a 2/2–way valve body. The actuator is made of PA or, for special operating conditions, PPS. The reliable self–adjusting packing gland provides high sealing integrity. These maintenance–free and robust valves can be fitted with a comprehensive range of accessories for position indication, stroke limitation or manual override. The Type 2012 features bubble–tight shut off, ISA S75.03 Face–to–Face dimensions and a stainless steel 316L valve body.
It is not recommended to install a globe valve upside down as it can cause dirt to accumulate in the bonnet. The preferred orientation of a globe valve is upright, however the valve may be installed in other directions, but any deviation from vertical is a compromise.
Globe valves are considered to be directional and must be installed with the pressure side or inlet under the seat. The valve must be installed in relation to the media flow as indicated by the flow direction arrow marked on the valve body.
A globe valve can be used either as an isolation valve or a regulating valve, depending on its trim. Globe valves are primarily designed to regulate flow in the partially open position, while gate valves are designed for the fully opened or fully closed position. If you want to use a globe valve for isolation we recommend careful consideration of which globe valve you choose, as maintaining a tight seal against the strong force pushing up on the disc is very difficult.
While both valves operate in a linear (up and down) motion, a gate valve uses a gate to restrict flow, whereas a globe valve has a plug.
A globe valve is most suitable for steam as the design of the valve allows for less wear on the seat compared to other types of valve. A globe valve’s design also allows for fine control and throttling.
