Brief analysis of the development status of "regulating valve mode"

Regulating valve product history can be traced back to the earliest self-operated regulating valve, its most original structure is a ball valve with a hammer, the use of hammer balance spool by the fluid action to adjust. This regulating valve later evolved into the use of the pressure after the valve to regulate the self-regulating valve.

Brief analysis of the development status of "regulating valve mode"

In the 1930s, the types of products have been many, the valve body shape for the spherical spherical valve to become a representative product, after the 1940s, Angle valve, butterfly valve, diaphragm valve and ball valve have emerged, has occupied a dominant position in the market, a variety of products have been complete. After the 1960s, the sleeve valve quickly attracted attention and became the mainstream products of spherical valve. The new product that appeared in the 70's is CAM flexure valve, its capacity is large, flow path is simple, unbalance force is small, these advantages make it become the leader of Angle stroke valve.

During this period, a variety of valves have been refined and developed into series. With the gas at the same time, the side force increasing type valve (also called Σ F type valve), successful development due to its unique structure, installation height is small, can increase strength, so welcomed by many factories and customers. Starting in the 80 s, people have created a variety of light (or called pure small) regulator, its main characteristic is, in the pneumatic actuators with multiple root spring instead of a big spring, in this way, pneumatic actuators can be new face in due course, it makes the regulator miniaturization, high capacity, the actuator is likely to replace the old heavy actuators. In the 1990s, due to the emergence of intelligent valves, the development of regulating valves turned a new page.

China's pneumatic control valve production industry started late, the relevant factories and departments designed and produced by themselves through the single seat control valve, two-seat control valve, three-way control valve, high pressure control valve, butterfly valve, long stroke actuator and valve positioner and other traditional main products are still in use.

China's pneumatic control valve leap is from the 1980s, many factories have introduced foreign advanced technology, in improving the performance of the original products, further standardization and serialization of the base, has developed side mounted pneumatic control valve and light control valve and other new products.

Now the valve market competition is fierce, regulating valve manufacturers only continue to innovate and improve their products, in order to occupy a certain dominant position in the future market.
