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 the outer body. Fluid circulation is controlled by a disc that gets away from valve body when fluid pressures and returns to its previous position when the pressure stops.
Swing check valves are designed and manufactured according to the
Iranian National standard No. 3664 is made of hot forged brass. The main form of ribs is calculated
in inches based on EN ISO-228 Standards. Swing check valves are usually used 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. following 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.
