Wafer Swing Type Check Valve
Product Overview:
The Wafer Swing Type Check Valve is a reliable, high-performance valve designed to prevent backflow in pipelines and ensure that fluids flow in a single direction. This valve features a swing-style disc that automatically opens with forward flow and closes when the flow reverses, ensuring tight sealing and protection against reverse pressure. Built for durability and high reliability, it is ideal for use in water, oil, steam, and chemical pipelines.
This valve is available in various pressure ratings (up to 4.0 MPa), making it suitable for a wide range of industrial applications.
Key Features:
-
Wafer Design: This compact design allows for easier installation between flanges and reduces the overall weight of the system.
-
Self-Closing Mechanism: The valve automatically closes when backflow is detected, preventing damage to the system.
-
Durable Construction: Made from high-quality materials like WCB, SS304, and CF8, this valve is designed to handle extreme conditions.
-
Corrosion Resistance: With a choice of corrosion-resistant materials, it ensures reliable performance even in harsh environments.
-
Wide Pressure Range: Available for pressures from 1.0 MPa up to 4.0 MPa, offering versatility across industries.
