The Pump Relief Valve Cavity Plug secures and seals the internal cavity of the relief valve within the electric staircase pump system. It maintains system pressure and prevents unwanted leakage of fluid from the valve chamber. It contributes to consistent hydraulic pressure control during pump operation. It helps the pump maintain proper direction and flow of hydraulic fluid. This plug is necessary for ensuring reliable pressure regulation by isolating the unused cavity and avoiding pressure imbalance.Attributes:• Prevents leakage of hydraulic fluid from the relief valve cavity.• Provides controlled sealing to avoid contamination inside the pump.• Supports consistent operation of the electric staircase pump.Applications:The Pump Relief Valve Cavity Plug is located in the relief valve cavity of the electric staircase pump and serves to seal off the chamber, control hydraulic pressure, and ensure stable fluid flow without leakage and pressure loss during operation.
