PMSS Ball Valves

PMSS Ball Valve: Primary Metal Seated and Secondary Soft Seated

​

The HPM Flow Solutions engineers designed and validated an advanced Primary Metal Secondary Soft Seat (PMSS) for the HPM Flow Solutions ball valves that provides;
• The primary metal seat protects the soft seal and ensures fire safe feature.
• The soft seat ensures bubble tight sealing. The flexible soft sealing in the seating rings is first effective at low pressure ranges.
The selection of the soft material (HNBR 95 Shore A) was accurately made to provide a broad temperature range and extra-long lifecycle.
