Glob valve is the most frequently used valve type in installations all over the world. Like all frequently preferred products, the technology of these valves is developing rapidly. They are durable and long-lasting, suitable for frequent opening and closing. Glob valves, which offer precise flow control, are suitable for use at high pressure and temperature. The most important reason why these valves are frequently preferred is their successful sealing at three different points. These valves, which owe their circuit tightness to the system that closes with the pressure of the rotating valve flywheel, provide external sealing with two different solutions. It guarantees the sealing between the body and the cover with a gasket, and the sealing from the movement shaft to the external environment with packing rings. Glob Valve Types The globe valve, which is the most commonly used valve type in installations all over the world, has three types with different sealing methods. Pressure Globe Valve The sealing system in pressure type valves is made by closing the valve, which is a metal closing element, by sitting on a metal disc. In other words, the sealing system is metal-metal. Metal Bellows Globe Valve The shaft sealing systems of these valves are developed with stainless steel bellows. In other words, the sealing system from the shaft bearing of the valve to the outside is supported by the bowl-bellows-shaft system installed between the cover and the body. There is also a packing group as a temporary solution against the risk of leakage as a result of problems that may occur in the bellows.
