CHECK VALVE – KRD-SCF
Strong, bolted bonnet leakproof swing check valve is cost-effective to prevent backflow in the pipeline.
A swing check valve uses a flapper that swings on a hinge or shaft.
A swing check valve is desinged to prevent the medium in the pipeline from flowing back.
As pressure reaches zero, the valve shuts fully to prevent backflow.
Some common applications for swing check valves are firefighting equipment, flood control in sewage systems, and toilet flushing.
