Severe-service ceramic valves · Engineering and manufacturing in Yantai

Solutions

Select by process duty and failure mode.

An industry name is only context. A useful recommendation connects the process system and application point to the medium, pressure, temperature, solids and the way the current valve fails.

Chemical processing facility

Chemical processing

Corrosive media, crystallization and pressure reduction

Coal conversion, fine chemicals, soda ash, phosphorus chemicals, PTA and resin processes can combine corrosion with particles, flashing, scaling and high differential pressure.

Review
Composition, concentration, solids, temperature, inlet and outlet pressure, control range
Typical failures
Erosion, corrosion, seizure, crystallization, leakage and short trim life
Relevant families
FCCV ball valves, FCRV rotary valves, FCAV angle valves and ceramic-lined flow paths
See chemical-process cases
Power generation facility

Power and environmental

Ash, desulfurization slurry and waste-treatment duties

Power and environmental systems often expose valves to abrasive particles, slurry, corrosive chemistry, deposits and repeated cycling across variable loads.

Review
Particle size and content, slurry density, chemistry, cycle frequency, shutoff requirement
Typical failures
Seat erosion, stem wear, leakage, deposits, blockage and frequent maintenance
Relevant families
FCCV, FCSV, FIBV, feed and discharge valves, ceramic-lined piping
Read the desulfurization case
Mining and mineral processing operation

Mining and minerals

Abrasive slurry, hard particles and long conveying lines

Ore processing, hydrometallurgy and slurry transport can combine high solids content, large or hard particles, corrosive chemistry, scaling and unstable flow.

Review
Mineralogy, particle distribution, solids content, velocity, settling, line pressure
Typical failures
Body washout, trim erosion, plugging, scaling and loss of shutoff
Relevant families
FCCV6, FCRV, FCSV, FERV and ceramic-lined piping

Steel and advanced-materials industrial facility

Steel and advanced materials

Powder injection, residue recovery and material-sensitive processes

Steelmaking, lithium salts and advanced-material processes may require powder handling, erosion resistance, clean flow paths, low-flow control or material-specific construction.

Review
Powder properties, gas-solid ratio, control range, contamination limits, temperature
Typical failures
Disc and seat erosion, powder ingress, unstable feeding, contamination and leakage
Relevant families
ESFV, FRFV, FIBV, FCCV7 and application-specific ceramic valves

Connect the failure to the review data.

This matrix is a conversation starter. Final material, geometry and actuation still depend on the complete operating conditions.
