定义
A precision-engineered sealing element designed specifically for sanitary pressure relief valves, creating a hermetic seal between the valve seat and disc to prevent fluid leakage under varying pressure conditions. It ensures zero contamination in hygienic applications by maintaining system integrity and preventing backflow.
工作原理
The seat seal operates on compression sealing principles where controlled deformation creates a tight interface between mating surfaces. When the valve closes, the seal compresses against the valve seat, forming a barrier that prevents fluid passage. During pressure relief events, the seal maintains contact until predetermined pressure thresholds are exceeded, then allows controlled venting while preventing contamination ingress.

常见问题

How often should sanitary seat seals be replaced?

Recommended replacement every 12 months or 5,000 cycles, whichever comes first, depending on operating conditions and cleaning frequency.

Can seat seals be autoclaved?

Yes, FDA-compliant EPDM seals withstand standard autoclave conditions (121°C, 15 psi) for up to 30 minutes without degradation.

What causes seat seal failure in sanitary valves?

Common causes include chemical degradation from incompatible cleaning agents, excessive compression leading to permanent deformation, thermal cycling fatigue, and particulate abrasion from system contaminants.
