Generally, when the control personnel are in the station or control room, they are required to have reliable control performance on the valve, and the valve itself is required to have protective and explosion-proof measures. Especially for long open valves, it is required to cut off accurately in case of sudden change. Therefore, reliable control performance has become the focus. In view of the above conditions, Q41WC series of sulfur resistant pipeline valve hard sealed pneumatic ball valve has been launched. The ball and integral seat are coated with chromium carbide and tungsten carbide using rocket application technology. This will increase the surface hardness by nearly an order of magnitude, which is superior to the conventional welding overlap reinforcement technology. The high-strength inconel x-750 spring forces the valve ball into the valve seat. This design solves many of the problems that occur in the setting up of trunnion bearings and corrosion. The free clearance between the valve ball and the valve seat is eliminated. Unlike the floating pneumatic ball valve, the design does not require upstream pressure to provide a tight seal. The spring makes the valve self compensating and provides anti-static protection.

When selecting the pneumatic switch ball valve, we must select the one with superior quality, because the high-quality pneumatic switch ball valve can not only reassure the majority of industrial manufacturers in terms of potential safety hazards, but also improve the product quality of the entire industrial enterprise. With better quality, consumers will have a higher desire to buy, and the income of the industrial enterprise will also increase significantly.
