INFORMATION

Nozzle check valves are one of the best check valve designs in terms of some features ;- Fast respond to the �ow changes- Very short closing stroke- Low weight moving parts- Non-slam closure- Low head loss

The dynamic design of the internal parts and the springs which are selected according to the pumping characteristics allow the valve to respond to the �ow changes.

The most important bene�t of nozzle check valves is, the long troble-free service life. The moving parts are not subjected to shocksand mechanical e�ects. There are no elastomeric parts which are subjected to wear.

Check Valves

Slanted seat check valves are so designed that the seating plane makes an angle with the vertical plane to reduce the swing angle and closing time.

These check valves can be used in all non return applications.

- Better closing characteristics due to the smaller swing angle of the disc.

- Closing time is reduced compared to the other check valve types

- Because of non extended shaft design, no sealing friction at the shafts

- No lever and counter weight requirement. Thus dangerous movement of external parts is eliminated

- Metal to metal or resilient seating options

- Maintenance free design

If the back flow reaches to check valve before the disc closed, the result will be slammed closing and water hammer.

Tilting Disc Check Valves With Hydraulic Damper eliminate the closing slams and water hammer for entire closing stroke.

Closing speed is adjustable depends on working conditions.

All components of the valve are designed for high stress occurred during damping effect.

On request slanted seat check valves are equipped with hydraulic end stage dampers in order to prevent the water hammer in pumping stations.The end stage damper is active at the last 10% of closing stroke. In case of power failure at the pumping station the disc closes very fast until reaching the damper that is why the back flow passing through the check valve during closure is minimum. This type is one of the best check valves when the turning back of pump’s impeller is critical. Damping effect can be adjusted by the help of integrated needle valve on damper according to the pumping and working conditions. The end stage damper is not linked to the disc and does not resist to open that is why headloss of this type is less than the types with the dampers linked to the levers.
