One-way valves are widely used on many systems such as: Water supply and drainage systems, fire protection systems in apartment buildings, high-rise buildings, commercial centers, and urban areas today. Systems of factories, industrial parks, factories, ventilation systems, fire systems, air conditioning systems, and wastewater treatment systems cannot lack one-way valves.
One-way valves in general have many advantages and have been used since ancient times:
– The biggest benefit of a 1-way valve is that it opens and closes automatically without the need for external force.
– Protects pumps and compressor equipment from damage caused by backflow/reverse flow
– Check valves are very effective in preventing water hammer
– Lower maintenance costs; Few moving parts
– Flexible to cope with changing flow conditions
– Simple and easy replacement without changing the pipe structure.
– Widely used in industry and life.
However, one-way valves also have some disadvantages:
– It is difficult to determine whether the valve is open or closed, because all of the valve's moving parts are located in an enclosed area.
– The valve disc may be stuck in the open position, or not closed tightly due to being stuck in waste and debris that has accumulated over a long period of time.
