Description

Ruisongbuild Industrial Wafer Check Valves: Compact Efficiency in Fluid Control

The Wafer Type Check Valve (also known as a Disc or Flap Check Valve) is the premier choice for modern industrial facilities where space and weight are critical factors. Unlike bulky swing check valves, the Ruisongbuild wafer design is installed clamped between two pipe flanges. This “thin-disc” technology allows for a significantly shorter face-to-face dimension, reducing the overall footprint of the piping system while providing robust, high-integrity backflow prevention in the most aggressive chemical environments.

High-Performance Material Matrix

• UPVC (Rigid PVC): The standard for cost-effective water treatment and irrigation (< 60°C).

• CPVC (Heat Resistant): Ideal for hot corrosive liquids and industrial process lines (up to 95°C).

• PPH (Chemical Grade): Exceptional for industrial acids and alkalis with high impact strength (up to 90°C).

• PVDF (Extreme Performance): The gold standard for ultra-pure water and highly concentrated halogens/acids (up to 140°C).

• FRPP (Reinforced): Glass-fiber reinforced for maximum structural stability in large-scale industrial wastewater.

Technical Specifications

• Type: Wafer (Disc) Type, Single Plate Flap.

• Size Range: DN50 to DN500 .

• Compatibility: Universally designed for ANSI, DIN, JIS, and ISO flange standards.

• Pressure Rating: PN10, PN16, or Class 150.

• Sealing Elements: FPM (Viton) or EPDM for perfect chemical matching.
