A Relief Valve Backup Ring works in conjunction with the sealing elements to prevent fluid leakage and maintain the desired pressure levels within the hydraulic unit. When the relief valve opens to relieve excess pressure, the backup ring ensures a tight seal against the valve housing. It acts as a barrier, preventing any leakage of hydraulic fluid through the relief valve assembly. The backup ring works in tandem with the sealing elements to ensure the integrity of the unit and avoid pressure loss or damage.Attributes:• Exhibits excellent temperature resistance, enabling it to function effectively even in extreme temperature conditions • Maintains the desired pressure levels, preventing pressure loss or damageApplications:A Relief Valve Backup Ring provides an additional layer of sealing to prevent fluid leakage and maintain unit pressure. It acts as a secondary barrier against fluid leakage.
