Pneumatic explosion-proof upward expansion valve is used for coating bottom discharge

VT Upward Expansion Pneumatic Bottom Valve Stainless Steel Upward Expansion Pneumatic Bottom Valve, Downward Expansion Pneumatic Bottom Valve adopts an integrated DC structure. The valve body of the Upward Expansion Pneumatic Bottom Valve is a streamlined unobstructed flow channel, and the inner surface of the flow channel is sandblasted, smooth and wear-resistant, with low flow resistance Soft sealing ensures zero leakage, while hard sealing is welded with Stellite alloy, which can be used in harsh working conditions such as high temperatures and media containing solid particles When used as a food medium, the inner surface is coated with Teflon, which has excellent corrosion resistance and meets hygiene standards. It is particularly suitable for working conditions in the food and beverage industries that require high hygiene standards The upward expansion type pneumatic kettle bottom valve has two structural forms, upward expansion type and downward expansion type, which are suitable for different reactor structures. It is suitable for fluid temperature range of -60~450 degrees Celsius and widely used in chemical, food, pharmaceutical and other industries for discharging materials at the bottom of reaction kettles.
