? 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
Widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, shipbuilding, metallurgy, energy system and other pipelines
