Disc/Seat is the sealing interface in pressure relief valves that controls fluid flow and prevents overpressure.
The Disc/Seat assembly in a pressure relief valve consists of two precisely engineered components: the disc (or poppet) that moves to open or close the flow path, and the seat—a stationary ring or surface that provides a sealing surface for the disc. This critical interface maintains system pressure within safe limits by allowing controlled release of excess pressure when predetermined setpoints are exceeded. The sealing quality directly determines valve leakage rates, reseat pressure, and overall system safety.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Common causes include: wear from particulate erosion, corrosion damage, thermal distortion, improper installation alignment, and seal degradation from chemical attack or extreme temperatures.
Inspect during annual valve testing per ASME requirements. High-cycle or corrosive service may require quarterly inspections. Replace if leakage exceeds manufacturer specifications or visible damage exceeds 0.1mm depth.
