Key Features of the FYL Wafer Butterfly Check Valve

1. Compact Structure & Easy Maintenance

Small volume, light weight and compact structure, directly installable between two pipeline flanges without additional space. Key components are easy to disassemble, reducing maintenance difficulty and cost.

2. Fast Automatic Closing & Strong Anti-Water Hammer Ability

Adopts antithetic valve board design, which closes automatically quickly under the elastic torque of torsion spring. Effectively prevents medium backflow and reduces water hammer pressure, protecting pipelines and equipment from damage.

3. Excellent Sealing Performance & Zero Leakage

Uses high-quality sealing materials and precision processing technology. After strict hydrostatic test, the leakage is zero, avoiding material waste and environmental pollution, ensuring safe and stable pipeline operation.

4. High Rigidity & Safe Reliability

Valve body is made of high-quality materials with good rigidity and impact resistance, able to withstand long-term medium pressure and impact without deformation. Passes multiple strict quality tests before leaving the factory.

5. Low Fluid Resistance & Energy Saving

Streamlined internal flow channel design minimizes frictional resistance and pressure loss, reducing energy consumption of connected pump units, achieving environmental protection and energy saving dual value.

6. Flexible Installation & Wide Application

Can be installed horizontally or vertically, no additional support required due to light weight. Compatible with various media, suitable for multiple industrial fields.
