Butterfly Resilient Seated | Keystone

Slurry Valves - Figure F990 - Ceramic Coating

Keystone Slurry Valves, Resilient Seated

Features & Benefits:

  • The ceramic coating is a coating and not a sealant. Therefore consideration of applications which involve pH levels outside the range of 3 to 9 must be addressed to Keystone.
