A brief discussion on the classification and characteristics of Throttle Valve

The Throttle Valve is a Throttle Valve that relies on the discharge of medium from the Universal Valve to drive or control the main valve. The Universal Valve itself is a standard spring direct-loaded Throttle Valve. Throttle Valve are automatic valves that are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important role in protecting personal safety and equipment operation. According to the opening height of the Throttle Valve disc, it can be divided into micro-open Throttle Valve and full-open Throttle Valve.

Throttle Valve are divided according to their structural forms and can be divided into pendulum type, lever type, spring type and (pulse type); according to the valve body structure, they can be divided into two types: closed type and non-closed type. A closed Throttle Valve means that the discharged medium does not leak out and is discharged to a designated location along the outlet. It is generally used in toxic and corrosive media. For air and steam Throttle Valve, non-closed Throttle Valve are often used. The selection of Throttle Valve products should be determined based on the actual sealing pressure. For spring-type Throttle Valve, there are springs with several working pressure levels within a nominal pressure (PN) range. When ordering, in addition to specifying the model, name, medium and temperature of the Throttle Valve, the valve body should also be specified. sealing pressure, otherwise the product is supplied according to the maximum sealing pressure.
Throttle Valve are suitable for high pressure and large diameter applications. The Throttle Valve has good sealing performance, and at the same time, its action is rarely affected by back pressure. The disadvantage of this kind of Throttle Valve is that its reliability is related to the main valve and Universal Valve. Its action is not as fast and reliable as the direct-acting Throttle Valve, and its structure is more complicated.
