Pneumatic ball valve can be divided into O-type ball valve and V-type ball valve. The O-type ball valve is of floating structure, the ball core is precision casting, the surface is plated with hard chrome, the valve seat is made of reinforced polytetrafluoroethylene material, the flow port is the same as the pipe diameter, the flow capacity is great, the flow resistance is very small, and there is no leakage when closing. It is generally used as an on-off valve, especially suitable for high viscosity V-type ball valves. The V-type ball valve is of fixed structure, and the ball core is provided with a V-type notch, It can shear fiber and granular media.

Corrugated hose is made of austenitic stainless steel materials or materials requested by users. It has excellent flexibility, corrosion resistance, high temperature resistance (- 235 ℃~+450 ℃), high pressure resistance (up to 32MPa). It can stop connecting in any direction in the pipeline to compensate temperature and absorb vibration, reduce noise, change the direction of media delivery To eliminate mechanical displacement between pipes or between pipes and equipment, double flange metal corrugated hose is particularly suitable for flexible joints of pumps, valves, etc. with displacement and vibration.
