TC NRV
A TC NRV is a sanitary non-return valve (NRV), also commonly known as a check valve, that features a Tri-Clamp (TC) connection. Its fundamental purpose is to ensure that fluid (liquid, gas, or steam) flows in one direction only and to automatically prevent backflow, thereby protecting the system from damage and contamination.
Working Principle
A TC NRV operates automatically, without the need for manual or external control. Its function relies on the differential pressure between the inlet and outlet of the valve.
Forward Flow: When the fluid pressure at the inlet side is sufficient to overcome the valve's closing mechanism (typically a spring or gravity), it pushes the internal component (such as a disc, ball, or piston) away from its seat. This opens the valve and allows the fluid to flow freely through the pipeline.
Backflow Prevention: If the flow stops or attempts to reverse, the pressure at the outlet side of the valve becomes higher than the inlet pressure. This pressure, combined with the force of the spring or gravity, pushes the internal component back onto its seat, creating a tight seal and preventing any backflow.
