?
Performance:
? Tilting Check Valve, while allowing the flow moving to the desired flow direction, stops the flow when exposed to back flow
? 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 by force of extra weight ?and maintains 100% tight sealing.
? The body and the disc can be manufactured as cast iron and ductile iron and sealing seats are manufactured from stainless steel
? Hydraulic brake system can be assembled to disc closer unit if it is required at project. The rate of closure can be controlled due to tilting check valve with hydraulic brake system and the system passes to .? static position slightly. The installation equipment protected from impact strength. ?
