Critical sealing components in pressure gauges and relief valves that regulate fluid flow and maintain system pressure integrity.
The valve seat and disc are precision-engineered mating components that form the primary sealing interface in pressure control devices. The seat is a stationary annular surface, while the disc is a movable element that contacts the seat to create a leak-tight seal. In pressure gauges, they isolate the measuring element; in relief valves, they control overpressure release. Their geometric accuracy, surface finish, and material compatibility determine sealing performance, response characteristics, and service life in industrial fluid systems.

Wear results from cyclic operation, cavitation, erosion by particulate matter, corrosion from aggressive media, and galling due to insufficient lubrication or material incompatibility. Regular inspection and proper material selection mitigate these issues.
Leak testing follows ISO 5208 or API 527 standards using air or water at specified test pressures. Methods include bubble test, pressure decay, or mass flow measurement with acceptance criteria based on leakage class requirements.
Minor damage can be repaired by lapping, grinding, or coating reapplication if dimensional tolerances remain within specifications. Severe erosion, cracking, or permanent deformation requires replacement to maintain system safety.
