4、 Maintenance of pneumatic ball valve
Only when the pressure before and after the ball valve is removed can the pneumatic ball valve be disassembled.
During the disassembly and reassembly of the ball valve, it is necessary to protect the sealing parts, especially the non-metallic parts, such as the O-ring and other parts, with special tools.
When reassembling the valve body of the pneumatic ball valve, the bolts must be tightened symmetrically, gradually and evenly.

Scope of application of corrugated pneumatic butterfly valve: it requires a flexible escort pipe to prevent vibration, and it can be used for steam, gas, air, heavy oil, petroleum, chemicals, etc. Application characteristics and installation precautions of stainless steel hose connector
Stainless steel hose connector is mainly used for shock absorption connection and piping connection at the inlet and outlet of various pumps, valves, compressors, refrigeration units, etc. in pipeline engineering. It plays the role of shock absorption, noise absorption and flexible connection of pipelines. It can also absorb pipeline displacement, reduce equipment stress, and ensure the service life of pipeline equipment. The corrugated pipe of stainless steel flexible joint adopts a thin-walled multi-layer structure, with large flexibility and small rigidity. The product adopts a flanging structure, without circumferential welds, corrosion resistance, high temperature resistance, aging resistance, no disclosure, long service life, non-toxic products, and can be used in drinking water pipelines. The product has its own pull rod, and the internal pressure thrust is self-locking, which is convenient for the setting and installation of the pipe support.
