Sharia Exports

Unique Features

•      Its main function is to allow the fluid to pass through only in one direction and avoid emptying situations in the line.

•      Work with automatic action without need of external control and dependence as it works on the sense of flow or the pressures in the piping system.

•      Provided with flap for easy operation.

•      Designed for 10 kgf/cm² working pressure.

•      Necessary to avoid water hammer for all types of installations where pump is used.

•      Compact design: Requires little space in piping systems due to it's short overall length.

•      Light weight: Much less in weight compared to conventional flanged end swing check valves.

•      100% Tight shut-off: The replaceable soft seal fitted in the body ensures a tight shut-off to prevent backflow thus protecting equipment, such as a pump.

•      Extremely low opening pressures.

•      Easy installation and maintenance.

•      Available in ¾", 1", 1¼", 1½" and 2" sizes in PN 10 pressure class.

•      The Swing check valve is highly resistant to corrosive chemicals, acids and alkaline substances.

May be used either vertically or horizontally.

NRVs has only one movable part i.e. spherical ball. This ball works as closing member to block the reverse flow of water when flow is stopped. NRV remains always in open position when the water is flowing through it. When the flow stops, the ball moves towards its seat and creates positive seal to prevent the reverse flow. These ball type NRVs can be installed horizontally as well as vertically. While using in vertical applications, the valve should be placed in such a way that the flow is always in the upward direction.
