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.

Metal material valves: such as copper alloy valve, aluminum alloy valve, lead alloy valve, titanium alloy valve, monel alloy valve, cast iron valve, carbon steel valve, cast steel valve, low alloy steel valve, high alloy steel valve. Metal valve body lining valve: such as lead lined valve, plastic lined valve, enamel lined valve.
