A check valve, sometimes referred to as an NRV (Non-Return Valve), is a valve that only permits one direction of fluid (gas or liquid) passage. In low-pressure, non-corrosive, and chemical-resistant applications including irrigation, water treatment, and specific chemical processes, PVC (polyvinyl chloride) valves are commonly utilized.A PVC non-return valve is a kind of check valve that prevents backflow by allowing fluid (gas or liquid) to flow in only one direction. PVC, a lightweight, corrosion-resistant plastic frequently found in industrial and plumbing piping systems, is used to make it.

A Non-Return Valve (NRV) composed of polyvinyl chloride (PVC) is known as a PVC NRV.A polyvinyl chloride (PVC) valve known as a PVC Non-Return Valve (NRV) is built to only permit one direction of fluid (gas or liquid) passage. Another frequent name for it is a check valve.A PVC Non-Return Valve (NRV), sometimes referred to as a check valve or one-way valve, is a mechanical device composed of polyvinyl chloride that permits only one direction of fluid (gas or liquid) passage.

Its main purpose is to stop backflow, which can lead to contamination, damage to the system, or problems with pressure.A PVC NRV is a mechanical device that permits just one direction of fluid (gas or liquid) passage. The fluid is automatically stopped from flowing backwards.This is essential for preventing contamination, pressure surges, and backflow from damaging pumps, pipelines, and other equipment.
