Pneumatic Tank Bottom Angle Valve FREE-Valve's Pneumatic Tank Bottom Angle Valves are designed for the convenient and fast discharging the material or samples from the bottom of the reactor, drain or feed vessel .The valve can be welded or installed on the vessel through the flange at the bottom of the valve , tank bottom angle valves are most commonly installed on feeding of vessels or dead space free draining and pipelines. Features 1.This range of manual control tank bottom angle valve is manufactured in integrated structure. 2. Structures with disc opening into the tank and disc opening into the valve. 3. Available with 45 degree outlet angle in the body. 4. A rotation-resistant device is set up to ensure that the valve stem only has straight line motions and no rotation. 5.The protection plate makes for the outstanding erosion resistance and corrosion resistance of the valve body. 6.The sealing surface of t he valve seat and the valve disc is made of over laying cemented carbide or painted with tungsten carbide.
