Donjoy Mixproof Tank Outlet Valve is designed to connect to the tank bottom. This valve is remotely controlled through compressed air, it’s an NC valve. The mixing proof valve is constructed with two independent plugs, which will form a leakage chamber that interlinks to the atmosphere under normal working status. When occasional failure of the medium leakage happens, the medium will flow into the chamber and be discharged at the out port, here it will see if any conk out or seat seal detected, preventing the possibility of products contamination due to leakage and conk out. When the valve is open, the leakage chamber is closed. Hygienic design meets US 3-A standard. It is widely used in the food processing industries, mostly in dairy and beverages.
