Why we use Check Valves or Non-Return Valves or one way valves?

Why we use Check Valves or Non-Return Valves or one way valves?

Sometimes reverse flow may be detrimental for equipment or process so it needs to be uni-directional for operational safety. This operational safety is accomplished by valve check. Valves check are self actuated and self operating devices.
Check   Valves   are used to protect the equipment that can be affected by reverse flow, such as flow meters, strainers and flow control valves.
Check   Valves   are used to check the pressure surges associated with hydraulic forces, for example, water hammer
Check Valves   are used to prevent the flooding that can take place if flow reversed.
Check Valves   are used to prevent the reverse flow on system shutdown.
Check Valves   are used to to prevent the flow under gravity.
Check Valves   are used for relief of vacuum conditions.
