Product Description
Our Wafer-Style Butterfly Check Valve is a specialized industrial one-way flow control device, designed to automatically prevent medium backflow in pipeline systems by relying on the flow of the medium itself to open and close the valve disc. Manufactured in full compliance with BS 1868 design standards, this valve features end flanges aligned with ASME B16.5, JIS B2212, DIN 2543, and GB9113 specifications, face-to-face dimensions meeting ASME B16.10 requirements, with all units inspected and tested in accordance with API 598 standards. Its working principle is simple and reliable: when the medium flows in the forward direction, fluid pressure pushes the disc open to allow unobstructed medium passage; when backflow occurs, the disc automatically closes tightly under reverse fluid pressure and its own weight, cutting off the flow immediately. With a compact, lightweight wafer structure, this valve is purpose-built for pump system operators, water treatment engineering teams, mechanical infrastructure contractors, and industrial facility maintenance teams working with space-constrained pipeline layouts.
Key Features & Industry-Leading Benefits
Ultra-Compact Wafer Design For Space-Limited Installations
Unlike conventional check valves, our wafer type butterfly check valve has an extremely short structural length, with a compact, lightweight build that simplifies installation and maintenance in tight spaces. It eliminates the need for extensive pipeline modification or large installation clearances, reducing layout difficulty and installation costs for industrial pipeline projects with limited mounting space.
Rapid Closure & Low Water Hammer Protection
The disc-shaped valve clack delivers exceptional response speed, closing instantly at the first sign of medium backflow. This rapid actuation drastically reduces water hammer pressure, minimizing impact damage to pipelines, pump bodies, and supporting equipment, effectively extending the service life of the entire pipeline system and reducing unplanned downtime caused by water hammer-related failures.
Low Flow Resistance & Energy-Saving Operation
The valve body features a streamlined internal flow channel with extremely low frictional resistance, minimizing pressure loss during medium transmission. This reduces the energy consumption of connected pump units, delivering long-term operational cost savings for industrial manufacturing facilities, municipal water systems, and commercial building infrastructure.
Durable Construction & Wide Media Compatibility
Available in sizes from 2” to 12”, with pressure ratings of 150LB to 300LB, and an operating temperature range of -20℃ to 350℃, this valve is compatible with water, oil, gas, steam, and other common industrial media. It offers robust material options including carbon steel (WCB) and stainless steel (CF8, CF8M) for the body and disc, with 304/316 stainless steel for internal pins and springs, ensuring excellent wear and corrosion resistance for long-term stable operation.
