What is a Wafer Type NRV?

Definition

A Wafer Type NRV (Non Return Valve) is a compact check valve installed between two flanges in a pipeline. It allows fluid to flow in one direction and automatically prevents reverse flow when pressure drops or flow direction changes.

Working Principle

The valve operates based on differential pressure. When forward flow pressure exceeds the cracking pressure, the disc opens. When the flow stops or reverses, the disc closes automatically, preventing backflow. This ensures pump protection, system stability, and prevention of contamination.

Types of Wafer Type NRV We Supply

Single Plate Wafer NRV

Compact design with a single swing disc. Suitable for water lines, HVAC systems, and low-pressure industrial applications.

Dual Plate Wafer NRV
