CHECK VALVES AND SHOCK ABSORBER SYSTEMS

Check valves are the key element in prevention of back flow and water hammer that can damage pumps and pipeline installations.

Generally, if the back flow reaches to check valve before the valve disc is closed, the result will be slamming in the valve closing and water hammer. Because of this hydraulic shock absorbers need to be installed .

Reverse flow has it’s static and dynamic component. Absolute size of static and dynamic back flow pressure and nominal size of the pipeline determined by the damping energy, which must absorb the damping units when the reverse flow occurred. Thus, back flow energy determines design and size of the check valves, damping characteristics, number and position of damping units.

For the check valves, design with disc and flaps, HYDROMAT offer different types of damping units and shock absorbers to check valve and system protection against back pressure and water hammer. It should not be forgotten that check valves are places of enormous flow losses, which means great financial losses. In that sense, HYDROMAT offers automated damping units that eliminate losses caused by this.

IMPORTANT

On customer request HYDROMAT offers complete equipment which means the check valve from different producers equipped with our damping system.
