Globe valves: Areas of application and industrial sectors

Globe valves are ideal for fast cycle duties, higher temperatures and control applications. Although they are often used for steam control and in the field of water/waste water treatment, they can handle the most diverse of applications in industrial processes, yet also in sterile and hygienic applications in the pharmaceutical, food and biotechnology industries.

 

Globe valves: Valve type

Globe valves are ideally suited for the control and regulation of mechanically pure, chemically inert or slightly corrosive liquids, gases or vapours.

This involves a gasket, generally made of PTFE, pressing against a seal seat, which then blocks the volumetric flow. A differentiation is made between straight seat and angle seat globe valves. The straight seat globe valve is often used for larger diameters and is also available in 3-way design, making it very good for mixing or switching tasks. A straight seat globe valve is also to be preferred where the valve is subjected to high stresses due to high flow velocities and regular readjustments. This is due to the more even distribution of force on the valve spindle. Angle seat globe valves are lighter and more compact and have a comparatively higher flow rate (Kvs value). All standard versions are already suitable for medium temperatures up to 180 °C and operating pressures up to 40 bar. In modified designs, temperatures of up to 300 °C can be handled without difficulty. The good mechanical properties of the globe valve design are particularly well suited to high cycle duties, filling and dosing applications. They are also the first choice for industrial or sterile steam generation and distribution.

For all the valve types specified, GEMÜ offers numerous customized accessories for automation and process optimization. Electr. position indicator, position and process controllers, sensor systems and measurement devices, are easily and quickly fitted, adjusted and integrated in the existing process control technology.
