High Performance Corrosion-Resistant DN80/100/150 300psi Industrial Cast Steel Flanged Swing Check Valve Non-Return Valve

Product Description

Product Description A check valve, also known as a non-return valve, is a type of valve that allows fluid (liquid or gas) to flow in one direction while preventing backflow in the opposite direction. It is an automatic valve, meaning it operates without manual assistance or external control.
Key Features of a Check Valve: One-Way Flow: Ensures unidirectional flow in piping systems. Automatic Operation: Opens and closes based on the pressure of the fluid. Prevents Backflow: Protects equipment and maintains system efficiency by stopping reverse flow. Versatility: Suitable for various industries, including water supply, oil and gas, chemical, and HVAC systems. Common Types of Check Valves: Swing Check Valve:
Features a disc that swings open or closed. Common in large-diameter pipes and systems with slow-flowing fluids. Ball Check Valve:
Uses a ball to block reverse flow. Compact and suitable for high-pressure systems. Lift Check Valve:
Has a disc or piston that lifts off its seat when flow occurs. Ideal for high-pressure applications. Wafer Check Valve:
Compact and lightweight design. Installed between two flanges in tight spaces. Diaphragm Check Valve:
Uses a flexible diaphragm to prevent backflow. Common in applications requiring a sanitary design. Dual Plate Check Valve:
Consists of two half-circle plates that open and close with flow. Lightweight and suitable for large systems. Advantages: Simple and automatic operation. Low maintenance. Available in a range of materials for different applications (e.g., stainless steel, bronze, plastic). Applications: Preventing contamination in water systems. Protecting pumps and compressors from damage. Maintaining pressure in pipelines. Product Parameters
