What is a PVC Non-Return Valve?
A PVC Non-Return Valve (NRV), or a PVC Check Valve, is a one-way valve that permits the flow of fluids in a single direction and automatically blocks reverse flow. It is significant in ensuring that pipelines, pumps, and equipment are not ruined by backflow, pressure surge, and contamination.
These valves are made of Polyvinyl Chloride (PVC) which is lightweight, not corrosive and very tough, making them suitable for water treatment, irrigation, chemicals processing, and plumbing systems.
Working Principle of PVC Non-Return Valve
The valve is automatically operated depending on the pressure difference.
A valve disc or flap opens when the pressure in the upstream is greater than the pressure in the downstream.
Fluid flows freely in one direction.
The valve closes automatically when the downstream pressure increases.
The disc closes in a tight-fitting manner, preventing reverse flow.
Types of PVC Non-Return Valve
PVC Swing Check Valve
Uses a swinging disc. Suitable in low pressure systems. Usually used in irrigation and drainage.
PVC Ball Check Valve
Stops reverse flow with a ball. Applicable to wastewater and slurry. The least amount of maintenance is needed.
Check Valve-PVC Spring-Loaded
Faster response time. Prevents water hammer. Applicable in pump discharge lines.
PVC Dual Plate Check Valve
Compact design. Applied industrial pipe. Large system high efficiency.
