Globe valves excel in pipelines requiring precise flow control and pressure drop, frequent operation, and exposure to medium to high pressures and temperatures. They offer more linear or percentage-equilibrium regulating behavior than globe and butterfly valves. Thanks to the perpendicularity of their sealing surface to the flow axis, they guarantee reliable and long-lasting sealing. Their disc geometry allows for surface regeneration during frequent opening/closing cycles, thus ensuring stable sealing and low leakage.

The metal-on-metal interlocking design withstands high temperatures and frequent handling, making it the preferred choice for steam and heating systems. The metal bellows design minimizes the risk of seal leakage, as the bellows seals the shaft. Safety standards are enhanced for toxic, flammable, odorous, or environmentally harmful fluids, and the system operates reliably within the PN16 to PN40 pressure range, from -10 to 220 °C. The piston system with a metal ring on a rubber band eliminates impurities and sediment upon circuit closure, thus reducing maintenance intervals in processes with slurries and applications requiring low leakage rates.

Globe valves are the most suitable type of conventional valve for flow control; their narrow bore creates a controlled pressure drop, allowing for precise flow rate adjustment. This naturally results in a greater continuous pressure drop than with a ball or butterfly valve; this reduction must be factored into energy cost calculations. High differential pressure and low suction pressure in liquids create a risk of cavitation and noise; this risk is mitigated by carefully selecting the thermal (Kv) and acoustic (Cv) expansion coefficients, a gradual pressure drop, and, if necessary, the use of a pressure reducer or a multi-port device.

The use of GG25/GGG40 cast iron for the body and cover, AISI 304/316 stainless steel for the shaft and fluid contact surfaces, and high-temperature bearing surfaces for the steam and condensate lines, provides a reliable solution. External sealing is achieved with graphite/PTFE gaskets or bellows; a suitable seal at the body-cover junction ensures resistance to thermal cycling. Typical industrial configurations operate in pressure classes PN16 to PN40 and at temperatures ranging from -10 to 220 °C; for more demanding processes, the seat materials and design must be adapted.

During installation, the flow direction indicated by the arrow must be observed, and the valve body must be tension-free and aligned. Vibrations and stresses in the piping can damage the disc and seat surfaces. The packing should be tightened gradually during initial commissioning, and slight periodic retightening is necessary during hot operation due to thermal deformation. Even for bellows valves, the replacement packing should be checked routinely as a precaution. Common failures include disc scoring by deposits, seat deformation due to incorrect tightening torque, and corrosion due to unsuitable materials. Piston valves reduce these risks in porous media; however, the use of a pressure filter/strainer will extend the valve's service life.
