Check valves for water

What are check valves?

Check valves are known as fluid control devices that stop the flow of media in the piping system into one direction. This check valve functions play different roles in the other many industries. These are also known as non-return, backflow, one way, check valves that prevent flowing media from flowing back.

Role of check valves for water

Some of the water application for check valves includes:

1.       Protection of upstream equipment

Water backflow can easily damage compressors, meters, pumps and other devices for unidirectional flow. Water hammering is another kind of potential dangerous phenomenon. Check valves helps in reducing the effects of water hammers especially when the valves are equipped with stage dampers.

2.       Preventing contamination and mixing

To prevent the reverse flow check valves helps in preventing the mixing of different media between two reservoirs. In a waiter treatment plant check valves help in preventing water from flowing back into the untreated water reservoirs.

3.       Prevent from drainage

When water is pumped from the suction reservoirs to the discharge reservoir reverse of flow is to occur when the pump is stopped. Check valves are actually used to prevent this kind of drainage. These kinds of valves are commonly used for this, called the foot valve.

Uses of check valves for water usage

Check valves are a common sight in industrial systems and they are used to remove waste water and other fluids. These are features as a single outer and an inner from where water can pass through it but they are back up. These are operated by the pressure that is according to poco products.

The check valves are actually the one way valve in which the flow can run freely one way but if the flow turns the valves it will close itself to protect the other valves, pumps and the piping systems. If no check valve is installed and the flow is turned water hammer can occur anytime.

Any spring loaded or any poppet style check valve is going to save the water hammer because they close itself before the reverse flow begins. The flow is done mostly in horizontal and in vertical position with primary spring selection.

How do check valves work for water hammer?

The check valve comprises 2 ports: an outlet and an inlet and a closing and shutting off mechanism. The characteristic of check valves that distinguish them from different types of ball and butterfly. Like these valves that require some kind of form actuation to function, the check valve is self-operating. Check valves

The function of check valves automatically relies on different pressures to affect its control. Check valves are closed in the default position. When water flows from the inner port its pressure opens the closing machines.

 The check valve closing machines are held in a loaded spring by a counter weight or by gravity. Check valves do not operate on different pressures alone. Minimum pressure is required to open the check valves as it is known as cracking pressure.
