Valves & Dampers
Industrial valves and dampers for corrosive and general service.
What we source
- Gate, ball, butterfly and control valves
- PTFE- and PFA-lined valves for corrosive service
- Knife-gate and slurry valves
- FRP-lined dampers for corrosive gas
- Isolation and control dampers
- Actuators and accessories
Sourced, quality-controlled and expedited by Crimar’s professional procurement team in China — with the same inspection discipline and documentation we apply to our FRP equipment.
Valves and dampers for corrosive and high-temperature service
Isolation and flow control is where a process plant is won or lost. Corrosive slurries, acidic gases and abrasive solids destroy standard valves and dampers quickly, so material selection matters as much as the mechanism. Crimar supplies industrial valves and large-diameter dampers — including FRP-lined and fluoropolymer-lined designs — engineered for exactly the chemistry, temperature and duty of your service.
Dampers are a Crimar specialty: we regularly engineer and supply large-diameter, FRP-lined butterfly dampers for corrosive flue-gas isolation, with manual or actuated operation — see our FRP-lined damper project for a real example, or our FRP dampers & expansion joints product line.
Dampers we engineer and supply
FRP-Lined Butterfly Dampers
Large-diameter (DN1300–DN1800 and up) carbon-steel butterfly dampers lined with FRP for corrosive, high-temperature flue-gas isolation.
Actuated & Manual Dampers
Manual worm-gear operators or electric and pneumatic actuators with position feedback for remote isolation and modulating control.
Isolation & Control Dampers
Guillotine, louver and butterfly dampers for isolation and flow control, tight shut-off classes, and export-ready packing.
Industrial valves for every duty
Crimar sources a full range of industrial valves, with materials and linings matched to the service — from clean utilities to aggressive slurry and acid:
- Isolation valves: gate, ball, butterfly and knife-gate valves
- Control & check: globe, control, check and non-return valves
- Safety & service: safety-relief, ventilation and specialty valves
- Corrosion-resistant: PTFE- and PFA-lined valves, rubber-lined and alloy trims for acid and slurry duty
Manual, gear, electric or pneumatic actuation is specified to suit the application, with the same documentation package as the rest of our equipment.
Sourced, tested and documented
Valves and dampers are pressure- and seal-tested before shipment, with material certificates and test records supplied. Crimar audits the manufacturers and arranges third-party or customer-witnessed inspection where required. See our quality & inspection approach or browse all sourced equipment.
