Wafer Check Valve

Product Overview

The Spring Loaded Wafer Check Valve is a compact, high-performance non-return valve designed to prevent reverse flow in piping systems requiring rapid closure and minimal pressure drop. Featuring a spring-assisted disc and wafer-style design, this valve ensures immediate sealing upon flow reversal, making it ideal for applications where water hammer prevention and space efficiency are critical.

Constructed from stainless steel, carbon steel, or ductile iron, this valve is durable and corrosion-resistant, suitable for water, steam, oil, and gas systems. Its lightweight, flangeless design simplifies installation and reduces system weight, while the spring mechanism enhances reliability in dynamic flow conditions.

Key Features

Spring-Assisted Closure:Integrated spring ensures rapid disc closure, minimizing water hammer and backflow risks.Low cracking pressure (as low as 0.1 psi) for efficient operation.
Wafer Design:Compact and lightweight, ideal for space-constrained installations.Installed between flanges without additional bolts or gaskets.
Low Resistance Design:Optimized flow path minimizes pressure drop, reducing energy consumption.Suitable for high-flow systems such as HVAC and water distribution networks.
Durable Construction:Body materials: Stainless steel (ASTM A351 CF8M), Carbon steel (ASTM A216 WCB), or Ductile iron (EN-GJS-400-18).Internals: Stainless steel disc and spring for corrosion resistance.
Compliance:Meets API 594, ASME B16.34, and ISO 17292 standards for industrial applications.
