KC-NRVH6s-19s Danfoss series Check Valves Mobile Machinery

NRVH is a check valve used in air - conditioning and refrigeration systems. When the forward fluid pressure acts, the piston in the valve is pushed open to allow the fluid to pass through. When the fluid flows in reverse, the combined action of pressure and spring force pushes the piston tightly against the valve seat to cut off the backflow, ensuring unidirectional fluid flow.
