Looking at the development in recent years, the domestic pneumatic butterfly valve is developing very rapidly, and more and more manufacturers are optimistic about the valve market. Many years ago, the products were basically introduced from abroad, such as the products in the hardware market, mainly Taiwan products. With the continuous development of domestic production technology, many manufacturers have launched a variety of models of valves to achieve "make in China".

Material and model selection of pneumatic butterfly valve
texture of material
Pneumatic butterfly valves are made of stainless steel 201, 304, 316L, etc.
model selection
The pneumatic butterfly valve is customized according to the diameter, total length, pressure, material, connection method and quantity provided by the customer.
Applicability of pneumatic butterfly valve connector
The connector is used to connect the hose to the threaded steel pipe or the equipment with external thread of outlet taste.
The metal corrugated pipe joint is made of high-quality zinc alloy die-casting and metalworking. The surface is generally galvanized and hard chrome plated. In special places, the surface is treated as requested. The product has beautiful appearance and tight structure; It has no pores, high strength, and can be connected with hoses, steel pipes and boxes. It has the advantages of good air tightness, shock resistance, corrosion resistance, waterproof, dustproof, etc. The specification size can be arbitrarily changed according to the equipment, box, steel pipe, hose diameter and thread. One end is connected to the hose (steel pipe), and the other end is connected to the switch box, motor, bridge, etc. Please indicate hose specification and thread size when ordering.
The joint can be directly welded:
1) It can be directly welded together without going through a third party to form a permanent joint that cannot be disassembled.
2) It can be completed by any welding process such as fusion welding, pressure welding, brazing, etc.
3) The directly connected welded joints have great application value in the consumption theory and are widely used.
4) The mechanical properties of welded joints are high.
