One piece wafer and lugged body for strength and stability in extreme environments.
Heavy duty top plate is drilled and slotted to ISO 5211 and other existing valve drillings, thus allowing ease of automation and interchangeability.
Two part polyester coated body provides a tough and durable coating against corrosion.
All 316 stainless steel discs are polished to a mirror finish.
Discs have a streamlined design, providing higher Cv and lower pressure drop.
Oversized shafts allow for greater strength and thus more stability to the disc.
A high strength machined Double D connection ensures a positive shaft-to-disc connection.
PTFE and elastomer are both vulcanized to a rigid phenolic ring. This cartridge seat provides a stable platform, eliminating movement of the PTFE and elastomer.
Torque fluctuation is eliminated by the consistent conformity of the seat, provided for by the cartridge design.
Cartridge design allows for full field replacement.
The Flow Line shaft seal is achieved through a continuous pressure exerted from the flatted area of the seat to the machined flatted area of the disc.
The raised flatted area of the seat corresponds precisely with the machined flatted hub area of the disc. These matching flatted surfaces provide a wide sealing area for the elastomer backed PTFE seat to exert pressure against, forming the primary seal.
Secondary sealing is provided by a 360° machined radius on the flatted hub.
