Pneumatic diaphragm regulating valves single-seat two-seater difference?

Pneumatic diaphragm regulating valves, since domestic production sales increasing year by year, has formed in the field of regulating valve pneumatic control valve, manual valve is complementary pattern. The pneumatic diaphragm regulating valves, covering several kinds, such as pneumatic membrane single-seat regulating valve and the two-seater regulator. So single-seat regulating valve and the two-seater regulator is what's the difference? First of all, the difference is mainly in the body, pneumatic single-seat regulating valve USES a direct single seat ball valve body, to its pneumatic two-seater regulator USES a two-seater ball valve body. Two different body also led to the two kinds of control valve performance, function, different parameters. Pneumatic single-seat regulating valve: is the top guide structure, with one ball valve body, because there is only one seat, for half a ball valve. So the body structure is compact, fluid channels in an s-shaped streamline, small pressure drop loss big circulation, adjustable range, flow characteristic of high precision. And guide part of the valve core area is large, has the characteristics of the seismic performance is strong. However, due to the single seat, so there is no suitable for medium size easily blocked, or high differential pressure environment. Widely used in building construction and general industrial water environment. As shown in figure 1. Pneumatic two-seater regulator: USES a two-seater ball valve body, the body of a flange at the bottom of the mouth, as a double seat, relative than single seat with the features of easy maintenance, stable structure therefore suitable for high pressure difference environment, therefore suitable for disassemble easily blocked medium. Generally suitable for high reliability, high pressure, high pressure difference and the fluid contained in the pulp easy plugging process conditions under the condition of good control. Widely used in industrial areas of complex working conditions. As shown in figure 2. Overall two-seater regulator due to the structure of stable and reliable than single-seat regulating valve is easy to remove. So will use a two-seater regulator in a more complex environment, but ordinary circumstances you just need to use single-seat.
