Performance: |
||
|
? Swing Check Valve, while allowing the flow moving to the desired flow direction, stops the flow when exposed to backflow |
||
|
? The disc hinged inside the body is placed within the flow section |
||
|
? With the start of movement at defined flow direction on the system, the disc leaves the flow section by turning in its axis and allows the flow pass |
||
|
|
||
|
? When the flow stops, the disc sits on the machined sealing seat through its own weight and maintains 100% tight sealing |
||
|
? Valve body and disc is cast Ductile iron, sealing surfaces are made of brass material or EPDM Rubber |
||
|
? Head loss is lower compared to other check valve types |
||
|
? Coated with fusion bonded epoxy |
||
