Non-Return Check Valve PVC, also known as NRV, is an essential component of any plumbing system. This valve prevents backflow of water or other fluids into the plumbing system, which can contaminate the water supply and thus damage the entire plumbing system.
In this blog post, we will discuss what NRV is, when it is used, types of NRV, and other technical details about the product.
What is Check Valve PVC NRV?
NRV is a type of valve that only allows fluid to flow in one direction. It works by automatically closing when fluid tries to flow in the opposite direction, thus preventing backflow. NRV is commonly used in plumbing systems to prevent contamination of the water supply, particularly in cases where there is a risk of cross-connection between potable and non-potable water sources (drinkable and non-drinkable water sources).
When is Check Valve PVC NRV used?
NRV is used in plumbing systems where there is a risk of backflow, such as in water supply systems, irrigation systems, and industrial processes. Backflow can occur when there is a drop in water pressure or when there is a cross-connection between potable and non-potable water sources. NRV is particularly important in cases where the non-potable water source is contaminated, such as in cases of sewage backup, chemical spills, or other similar events in the residential, commercial or industrial projects.
Applications of Non-Return Check Valve PVC (NRV)
NRV finds application across diverse plumbing systems:
- Water supply networks
- Irrigation systems
- Industrial processes prone to fluid reversal
It mitigates risks arising from pressure drops or inadvertent cross-connections, critical in settings like residential, commercial, and industrial projects.
Types of NRV
There are several types of NRV available in the market, each designed for a specific application. The most common types of NRV include:
- Swing Check Valve: A swing check valve is a type of NRV that uses a swinging disc to control the flow of fluid. When fluid flows in the correct direction, the disc swings open, allowing the fluid to pass through. When fluid tries to flow in the opposite direction, the disc swings shut, preventing backflow.
- Spring Check Valve: A spring check valve uses a spring-loaded disc to control the flow of fluid. When fluid flows in the correct direction, the spring compresses, allowing the fluid to pass through. When fluid tries to flow in the opposite direction, the spring expands, pushing the disc against the valve seat, preventing backflow.
- Ball Check Valve: A ball check valve uses a ball to control the flow of fluid. When fluid flows in the correct direction, the ball is pushed aside, allowing the fluid to pass through. When fluid tries to flow in the opposite direction, the ball is forced against the valve seat, preventing backflow.
- Diaphragm Check Valve: A diaphragm check valve uses a flexible diaphragm to control the flow of fluid. When fluid flows in the correct direction, the diaphragm flexes, allowing the fluid to pass through. When fluid tries to flow in the opposite direction, the diaphragm is forced against the valve seat, preventing backflow.
