Spare & Replacement Parts

Replacement seal kits are available for Nor-Cal Products butterfly valves. They contain the three O-rings that are needed to seal this valve. FKM seals are standard but other elastomers are available upon request. 
  • Fully opening for improved conductance
  • Aluminum body with or without hard anodization
  • Wide variety of O-ring compounds available
  • Sizes from 6" to 14"
  • Seals against 1 atmosphere delta-P
Nor-Cal Products provides a variety of vacuum isolation valves in addition to our poppet and gate valves. Manual butterfly valves provide a low-cost, o-ring sealed stem and plate option. Quarter-swing ball valves provide a somewhat more robust PTFE and ball seal for "dirty" applications, while bakeable all-metal valves are designed for ultra-high vacuum integrity in the most demanding vacuum applications, such as synchrotron rings and particle accelerators.
