Details Description
Swing Check Valves provide dependable, automatic protection against reverse flow in your piping systems. The simple hinge-and-disc mechanism ensures low flow resistance when open and positive sealing when closed. Ideal for pump discharge applications, these valves are engineered for durability and long service life, protecting critical equipment like pumps from damage caused by backflow.
When the pressure at the inlet end (upstream) is sufficient to overcome the weight of the valve disc and the fluid resistance, the fluid pushes the valve disc to rotate around the pin shaft to open.
When the inlet pressure drops or disappears, or even reverse flow occurs (backflow), the reverse fluid and gravity (or sometimes spring force) work together to push the valve disc to swing back around the pin shaft, quickly closing and sealing with the valve seat, thereby cutting off the flow. In the fully open position, the valve disc is almost parallel to the flow channel, causing very little obstruction to the fluid.
Features
• Low flow resistance: When fully open, the valve disc is completely suspended in the flow channel, causing very little pressure loss to the medium.
• Automatic operation: Completely driven by fluid power, without the need for external power or manual operation.
• Simple structure and convenient maintenance: few components, sturdy and durable.
• Low flow rate sensitivity: It can be effectively opened even at low flow rates and is suitable for a wide range of flow rates.
