Zhejiang-Naibang-Valve-Co-Ltd- (31)


The valve disc moves up and down along the midline of the valve body. Under the pressure of the fluid which flows in one direction, the valve disc will be raised up from the sealing surface of the valve seat. If there is backflow, the valve disc will return back to the valve seat to cut off the medium. It is  mainly  used  in  the fluid system  containing  strong  oxidative mediums,  like water supply system, heat  supply system  and  acid system  etc. It is always used as  accessory of  boilers.  
It has exquisite  profile  and  simple  structure.  Its  spring  device  functions  to  speed  up the closing movement of the disc so as to  eliminate  water  hammer. This valve is very suitable for space-limited locations.
