Product Overview
The SAGINOMIYA NBV-502BX is a precision-engineered refrigeration solenoid valve designed for reliable on/off control of refrigerant flow in commercial and industrial refrigeration systems. Manufactured by Saginomiya, a globally recognized leader in fluid control technology, this valve operates on an electromagnetic actuation principle, utilizing a solenoid coil to drive a plunger that opens or closes the valve port. The NBV-502BX is specifically configured for refrigeration circuits, ensuring positive shut-off and precise flow control of refrigerants including HFCs, HCFCs, and blended refrigerants. Its compact, direct-acting or pilot-operated design (depending on configuration) makes it an essential component for liquid line, suction line, and hot gas bypass applications in process cooling and HVAC-R infrastructure.
