Swing Check Valve

A valve through which the fluid passes in one direction and backflow of fluid is avoided. The valve acts only under the pressure of fluid having no controller device on outer body. Fluid circulation is controlled by a disc which gets away from valve body when fluid pressures and returned to its previous position when pressure stops.

Swing check valves are used usually in urban water supply, thermal installations of buildings, industrial purposes, pumps, petroleum and oil networks and generally in all networks in which the fluid flows only in one direction. Followings are benefits and advantages of this product:

  • Resistance against corrosion and tear
  • Resistance against sediments
  • Full sealing
  • Silent on-off position

Advantages

Mounting a sealing rubber washer of NBR Material on the steel disk (lid) will completely seal the waterway zone at the same time preventing the noises produced by impact of the disk against the valve body during on-off operations.
