Valve seats play a key role in the performance of control valves. Caldera’s ceramic-lined designs combine metal housings with engineered ceramic to provide significantly longer service life than traditional all-metal seats.

Segmented Seats for Improved Maintenance and Longevity

Caldera’s segmented seats are designed for easy maintenance and reduced long-term costs. Worn components of segment seats can be individually replaced. The segmented design also reduces stress on ceramic parts compared to single-piece seat constructions.

Ceramic-lined Seat Materials

Caldera uses advanced ceramics like silicon carbide and zirconia, paired with housing materials such as titanium alloys, nickel alloys, and super duplex stainless steels. These combinations are engineered to withstand corrosive and erosive process conditions.

Down Stream Protection

Supersonic flow exiting a valve can rapidly erode downstream piping and components. Caldera optimizes seat geometry to control flow direction and velocity, helping to reduce wear and extend equipment life across the system’s full operating range.
