Product Overview
The SAGINOMIYA SEV-603BXF is a direct-acting, normally closed (NC) refrigeration solenoid valve engineered for precise on/off control of refrigerant flow in commercial and industrial refrigeration circuits. Manufactured by Saginomiya, a recognized authority in refrigeration and air-conditioning control components, the SEV series is designed to deliver reliable magnetic actuation, bubble-tight sealing, and rapid response across a wide range of refrigerants and operating conditions. As a process and pneumatic valve, it functions as an electrically actuated flow control device—opening when the coil is energized and closing by spring force upon de-energization—making it ideal for liquid line, suction line, hot gas, and discharge line service in refrigeration and HVAC systems.
