Wafer Check Valve – Wafer Type Non Return Valve (NRV)

OEM Manufacturer & Exporter | MS • SS304 • SS316 • Cast Iron | India

A wafer check valve is a compact non-return valve (NRV) designed to prevent reverse flow in pipelines. It is installed between two pipe flanges and allows fluid to flow in one direction only. Due to its slim wafer-style body, it is ideal for applications where space, weight, and pressure loss must be minimized.

How a Wafer Check Valve Works

  • Forward Flow: Fluid pressure opens the internal disc or dual plates.
  • Reverse Flow: When flow stops, the disc closes automatically to block backflow.
  • Quick Closure: Spring-assisted designs reduce water hammer.

Types of Wafer Check Valves

Dual Plate Wafer Check Valve

Uses two spring-loaded semi-circular plates. Offers low pressure drop and fast response. Commonly used in high-flow industrial pipelines.

Single Plate (Swing) Wafer Check Valve

Features a single swinging disc. Simple construction and cost-effective for utility and general services.
