XQDF70 Series Rotary Ball Butterfly Valve Specially Used in Powder Lot Vehicle Powder Tank Truck (Wafer Type)-China top 10 valve Manufacturers, Suppliers, Factory

01. Specialized type—Rotary Ball Butterfly Valve Specially Used in Powder Lot Vehicle/Powder Tank Truck
02. The main structure is similar to a butterfly valve and uses a spherical valve core, so it is called a rotary ball butterfly valve
03. Upgraded products for ash discharge ball valves, compared to ball valves, the structure is short and the volume is small,
totally solved about 95% of the after-sales problems with ash discharge ball valves, the valve core with a knife shaped
ball port has a scraping and shearing effect on particles, debris, and scaling between the valve seats, the surface of the valve
seat is not prone to debris residue and scaling, and the hard seal has good wear resistance. Solved:
① The dust discharge ball valve is prone to damage to the PTFE valve seat and ball due to the wet adhesion of cement powder
on the sealing surface of the valve seat, which can cause leakage
② The problem of valve body perforation after using the ash discharge ball valve for a period of time
③ Problems such as freezing and unable to move the core of the ash discharge ball valve
04. The valve core and valve seat are sealed with curved surfaces, and the sealing surface can automatically locate and overlap
and compensate for wear, good sealing performance
05. Diameter range: DN100～125, nominal pressure: PN16bar
06. Applicable medium: Cement powder, coal powder and other powder materials
07. Applicable medium temp.: carbon steel Va:-29～350℃, stainless steel Vc:-40～450℃
08. Valve body material:cast steel WCB (code:C), SS304 (code:B)
09. Valve seat sealing material: normal alloy steel(code:H), special hard alloy(code:Y)
10. Can be installed at any angle, and the flow direction of the medium must be consistent with the arrow direction on the valve body
