The Solenoid Valve Backup Ring serves as an additional layer of protection by supporting the O-ring seals. It helps to ensure a tight and reliable seal between moving parts within the valve, such as the plunger and piston, and the valve body. By preventing fluid from bypassing the primary O-ring seals, the backup ring enhances the overall sealing performance of the solenoid valve, reducing the risk of leaks and maintaining system integrity.Attributes:• Provides effective sealing under high pressure.• Retains shape under pressure.• Good abrasion resistance.• Ensures reliable fluid containment.Applications: The Solenoid Valve Backup Ring is specifically used in solenoid valve assemblies where O-ring seals require additional sealing reinforcement, it is positioned between the O-ring seals and the moving parts of the valve to ensure effective fluid sealing.
