Disc Type Tank Bottom Angle Valve(referred to as Tank valve, Angle Bottom valve, Bottom drain valve, Flush mount valve etc) is designed to provide drainage and dead space free shutoff for reactors, vessels, autoclaves and storage tanks. The dead space free shutoff is accomplished by placing the valve seat flush with the bottom of the vessel. This eliminates any buildup of medium within the vessel nozzle itself. Features 1.This tank bottom angle valve is manufactured in integrated 45 degree Y type structure and 90 degree angle type structure; 2.Both rising disc type (the valve is opened into tank) and lowering disc type (the valve is opened into valve) can be designed; 3.Crust breaking for disc rising type, so anti-scaling function is avaliable. 4.The sealing surface of the valve seat and the valve disc is made of over laying hard alloy. The auxiliary line sealing guarantee the reliability of the sealing performance. 5.Pneumatic operation is used to save labor cost. Technical Specifications Size: 2�??~14� ??

Pneumatic Ceramic Double Disc Gate Valve FREE-Valves Pneumatic Ceramic Double Disc Gate Valve is mainly used in feeding and dumping the dry powder and the transport pipeline, which not only adopt toughening ceramic as shut off and wear out resistance material, but also design construction of autofrettage pressure self-sealing and valve disc auto-rotate, so as to the sealing surface within the dry powder get more wear resistance in process of opening and closing frequently, thereby, which guarantee the high requirements of sealing performance of this valve and long working time. Features: Sealing pair is made of structural ceramicswhich have perfect performance to resist wear and flushing. Two-side sealing can realized due to double plate structure of the pneumatic ceramic double disc gate valve It inserts spring between double valve discs to ensure self- sealing through bi-directional flexible preload pressure of spring, having characteristics of low pressure bi-directional sealing and without dust clogging phenomenon in the process of the opening and closing of valve.
