Features:The discs tightly cover the rubber with no iron exposed.The media are pledged clear and pure.The rubber-coating layer of the discs is added with durable nylon cord fabrics and soft mental cord fabrics,which greatly improves the discs' capacities of enduring flexing and stretch when unlocked or closed,meanwhile,
prolongs service life.
  When in the state of closedness,the discs form a certain angle with the flowing direction.
  The through-holes of the base and the discs are all oval while the flowing channel is straight-through.Therefore,the closed angle is relatively small,which decreases phenomenas of the water hammer, as a result,effectively secures the valve.
Application:The two kinds of valves are widely used in heating systems and industrial water supply and drainage systems
