FEATURES

• 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
