Compared with ordinary ball valves, Q71F Wafer ball valves have the advantages of short structural length, light weight, convenient installation. The valve seat adopts an soft sealing structure, which is reliable in sealing and easy to open and close. It is equipped with a refractory structure that is reliable and has good sealing in the event of a fire.

Application
The ball valve is suitable for PN1.0～2.5MPa, working temperature 29～180°C (the seat is reinforced PTFE) or 29～300°C (the seat is the PPL) on various pipelines, it is used to cut off or connect the medium in the pipeline. Different materials can be used for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
Strength
1. The unique design of the eccentric makes the frictionless transmission between the sealing surfaces, which prolongs the service life of the valve.
2. The elastically seat generated by torque.
3. Ingenious wedge design makes the valve have a tighter and tighter automatic sealing function, with compensatory and zero leakage between the sealing surfaces.
4. Small size, light weight, light weight and easy to install.
5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
6. Replacement seat material can be applied to a variety of media.
