The Grooved Swing Check Valve is a critical component in piping systems designed to prevent fluid backflow. Its operational mechanism relies on a gravity-driven swing disc: the disc opens only when fluid flows in the intended direction and automatically closes during reverse flow, ensuring system stability.
A key feature of this valve is its grooved connection, which simplifies installation compared to traditional flange or threaded connections—reducing labor time and improving efficiency in assembly. This design makes it a preferred choice in systems where quick setup and reliable performance are priorities, such as water distribution networks and fire protection systems.

The Grooved Swing Check Valve serves diverse sectors where backflow prevention is critical:
Water Treatment Plants: Prevents mixing of treated and untreated water, safeguarding water purity.
HVAC Systems: Maintains proper airflow direction, ensuring consistent pressure and temperature balance.
Fire Protection Systems: Critical for preserving water supply integrity, ensuring unidirectional flow during emergencies to support fire suppression.
Industrial Piping Networks: Protects equipment from damage caused by reverse flow, which could lead to contamination or operational failures.
Its main role is to allow one-way fluid flow while blocking reverse flow, maintaining system efficiency and safety.
The valve uses a hinged disc that swings open with forward flow. During reverse flow, gravitational force and fluid pressure push the disc against the seat, creating a secure seal.
Yes. In fire protection systems, it ensures water flows only toward sprinklers or hydrants, preventing pressure loss that could compromise emergency response.
Common materials include ductile iron, cast iron, and stainless steel—selected based on the fluid type (e.g., water, chemicals) and environmental conditions.
Unlike lift check valves or ball check valves, its swing mechanism allows smoother flow and quieter operation, with a less abrupt closing action that reduces water hammer risk.
This valve combines reliability, ease of installation, and versatility. Its grooved design simplifies retrofits or system expansions, while certifications like FM and UL validate its performance in critical applications. Whether in municipal water systems or industrial facilities, it provides consistent backflow prevention to protect equipment and maintain operational efficiency.
