STRUCTURES
Shaft Seal
elf-sealing Y-type or V-type rings provide excellent sealing, low abrasion and long service life when fluid pressure increases
Self-lubricating bearing
Stainless steel backed PTFE bearing is designed for superior lubrication with low maintenance.
Corrosion Resistant Shaft
Stainless steel backed PTFE bearing is designed for superior lubrication with low maintenance.
Streamlined Disc
Disc is available in either ductile iron with stainless steel sealing edge or all stainless steel. The spherical design permit efficient sealing.
Body
Body is available in cast iron or cast steel. Flange dimensions conform to ASME B16.1 class 125 or class 250
Disc
The dome-shaped disc reduces the resistance to the fluid and enhances its strength to be more reliable in service.
