Gerber offers a variety of different types of faucet and shower valves, including compression, ceramic, thermostatic, and pressure balance. Each has a unique application and benefit that it delivers to the both Gerber and Danze for a compelling value. Our valves are built on the foundation of Gerber reliability, helping to ensure that they perform consistently for the life of the product. Faucets that use a ceramic disc valve provide a lifetime of drip-free performance. The ceramic disc valve uses two ceramic discs to control the flow of water. When the faucet handle is in the “off'''' position, the two discs create a watertight seal to block the flow of water.
