Product Overview
The SAGINOMIYA SEV-502BXF is a normally closed (NC), direct-acting refrigeration solenoid valve engineered for precise on/off control of refrigerant flow in commercial and industrial refrigeration circuits. Manufactured by Saginomiya, a recognized leader in refrigeration and air conditioning control components, the SEV series utilizes a direct-acting plunger design that permits reliable operation independent of system pressure differential, ensuring positive shut-off even at low pressure conditions. The valve serves as a critical flow control element in liquid line, suction line, and hot gas bypass applications, providing dependable isolation and flow regulation within refrigeration and process cooling systems.
