GLOBE VALVES
Types of Globe Valves
Glob valve, which is the most frequently used valve type in installations all over the world, has three different types in terms of sealing methods.
-
Printed Globe Valves
Sealing system in pressure-type valves is made by closing the valve, which is a metal closing element, by sitting on a metal disc. So the sealing system is in the form of metal-metal.
-
Metal Bellow Sealed Globe Valves
Shaft sealing systems of these valves are developed with stainless steel bellows. Sealing of the shaft bearing is supported by the bowl-bellows-shaft system installed between the cover and the body. In addition, as a temporary solution against leakage risk as a result of problems that may occur in the bellows, there is a packing group.
-
Piston Type Globe Valves
Sealing system of piston type globe valves is metal to elastic. These valves have two ring-shaped elastic rings and a piston that enters them. This piston acts as a closing element. The pressure from the cap nuts wraps the piston in the rings with radial pressure. Sealing is provided by this pressure. Unlike other globe valves, the sediment and dirt that may form in the circuit are also cleaned thanks to the piston's closing style.
