Yone No. 112 Swing Check Valve ANSI Class 150
Durable Backflow Prevention for Industrial Flow Systems
Introduction: Why Valves Matter in Industrial Systems
In industrial operations, efficiency, safety, and reliability are all heavily dependent on the piping systems that transport fluids throughout the plant. One of the most vital components within these systems is the valve—a device that allows, regulates, or stops the flow of media such as water, steam, oil, gas, or chemicals. Valves ensure that flow is managed properly, process conditions are maintained, and system failures are prevented.
Among the many types of industrial valves, check valves serve a unique and critical purpose: they allow flow in only one direction and automatically prevent reverse flow. This is especially important in systems where backflow can damage equipment, contaminate clean process lines, or reduce overall efficiency. In this context, the Yone No. 112 Swing Check Valve ANSI Class 150 stands out as a robust, high-performance solution trusted across a wide range of industries.
Product Description: Technical Features, Design & Specifications
The Yone No. 112 Swing Check Valve ANSI Class 150 is engineered to deliver reliable backflow prevention with minimal pressure drop and long-term durability. Its swing-type disc design, bolted bonnet construction, and conformance to international standards make it ideal for critical flow applications.
How It Works
This swing check valve utilizes a disc mounted on a hinge or shaft. When fluid flows in the forward direction, the disc swings open, allowing flow to pass. When the flow stops or reverses, the disc automatically returns to its seat by gravity or back pressure, sealing the passage and preventing reverse flow.
This passive operation makes the swing check valve highly efficient and virtually maintenance-free, with no need for external power or control mechanisms.
Design Features
-
Bolted Bonnet
The valve is built with a bolted bonnet structure, ensuring ease of maintenance and providing a secure, pressure-tight seal. This design allows for easy access to internal components for inspection or repair. -
Swing Type Mechanism
The swing-type disc is optimized for low pressure drop and smooth operation. The disc swings open fully during normal flow, minimizing turbulence and resistance. -
Orientation Flexibility
Designed to be installed in horizontal or vertical lines, giving engineers flexibility in piping layout and space management. -
Durable Construction
Manufactured with high-grade materials to handle a wide range of industrial fluids, including corrosive or high-temperature media.

Product Applications: Where This Valve Performs Best
The Yone Swing Check Valve ANSI 150 is a preferred choice across a wide range of industries due to its effectiveness in preventing reverse flow, protecting equipment, and maintaining process integrity.
1. Oil & Gas Industry
In refineries, offshore platforms, and pipeline systems, backflow prevention is essential. This check valve ensures safety and avoids process contamination.
2. Water Treatment and Distribution
Municipal and industrial water systems rely on check valves to maintain pressure balance and prevent back-siphonage into clean water lines.
3. Power Generation
Used in cooling systems, boiler feed lines, and auxiliary loops to maintain flow direction and protect critical pumps and turbines.
4. Chemical and Petrochemical Plants
Backflow in chemical processes can result in dangerous reactions or contamination. Yone check valves provide reliable isolation between process zones.
5. Marine and Offshore Applications
Saltwater, fuel, and ballast systems require corrosion-resistant and durable valves that can perform reliably in harsh environments.
6. HVAC and Fire Protection Systems
In HVAC chilled water lines and fire suppression loops, swing check valves help maintain unidirectional flow and system integrity.
In all these applications, the Yone swing check valve offers performance and peace of mind for engineers, operators, and safety personnel.
