Wafer Check Valve

Product Overview

The Dual Disc Wafer Check Valve is a compact, high-performance non-return valve designed to prevent reverse flow in piping systems where space, weight, and efficiency are critical. Featuring a dual disc design, this valve ensures rapid sealing with minimal pressure drop, making it ideal for water, steam, oil, and gas applications.

Constructed from carbon steel, stainless steel, or ductile iron, this valve is durable and corrosion-resistant. Its wafer-style design allows for easy installation between flanges, reducing overall system weight and space requirements. The dual disc mechanism provides reliable sealing and reduces water hammer effects, making it a preferred choice for high-flow systems.

Key Features

Dual Disc Design: Two spring-assisted discs ensure rapid sealing upon flow reversal, minimizing water hammer effects. 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, eliminating the need for additional bolts or gaskets.
Low Resistance Design: Optimized flow path minimizes pressure drop, ensuring energy efficiency. Ideal for high-flow systems such as water supply and HVAC networks.
Durable Construction: Body materials: Carbon steel (ASTM A216 WCB), Stainless steel (ASTM A351 CF8M), or Ductile iron (EN-GJS-400-18). Discs and springs: Stainless steel for corrosion resistance and long service life.
Compliance: Meets API 594, ASME B16.34, and ISO 17292 standards for general industrial applications.

Operational Advantages

Rapid Sealing: Dual disc design ensures immediate closure upon flow reversal.
Energy Efficiency: Low pressure drop reduces pump energy consumption.
Compact & Lightweight: Saves space and simplifies installation.
