The explosion-proof pneumatic butterfly valve adopts the design scheme of neutral line structure without axial force, which has obvious characteristics of low torque in actual operation, and is reasonable when equipped with electric equipment; The rubber lining structure is selected, and the central convex surface of the butterfly plate is precisely machined to a high smoothness. The friction resistance of the rubber high-pressure gate valve is extremely low, and the service life of the valve is long; The flow characteristics of the valve plate protruding face are linear, with small flow resistance index and small valve flow resistance

Moreover, the current pneumatic ball valve has the function of insulation, fire prevention and self cooling. There is a temperature control material in the equipment itself, which can transfer temperature. The friction between parts in production will produce temperature, and long-term operation will increase the internal temperature of the machine. At this time, the temperature control system required can transfer and reduce the temperature, so that the subsequent operation of the machine will not be affected.
