Valve plates and flaps for discharge, isolation and flap valves in kilns, coolers and dust handling systems. Cast in heat-resistant Cr-Ni alloy steel or wear-resistant iron with flat seating faces, so they seal properly and resist the abrasive hot material flowing through them.

If you need detailed technical information, drawings or a price for a size we have not listed, please email us at cnwearparts@lyzhili.com — we are a customized factory for crusher and mill wear parts and we quote quickly.

Sealing and abrasion resistance in one part

A valve plate has to do two jobs: seal against gas or material flow, and survive the abrasion of hot, gritty product passing over it. Zhili casts plates with flat seating faces and hard, wear-resistant working surfaces, in alloys selected for the actual operating temperature.

Key features

  • Heat-resistant Cr-Ni cast steel and wear-resistant iron options
  • Seating faces flat and matched to the valve body
  • Hardfaced and bimetal variants for severe abrasion
  • Hinge, bolt and actuation details cast and machined to drawing
  • Chemical, hardness and dimensional reports supplied

Materials

  • Cr-Ni heat-resistant cast steel – high temperature, moderate abrasion
  • High-chromium white iron – maximum abrasion resistance
  • Cr-Mo alloy steel with hardfacing – structural strength with a renewable wear face

Applications

Kiln and cooler discharge valves, dust collector discharge valves, flap and isolation valves in cement, lime, power and metallurgical plants handling hot abrasive material.

Why buyers choose Zhili

  • Working from drawings, OEM references or worn plates
  • Alloy matched to both the temperature and abrasion duty
  • Consistent quality and dimension control, verified per batch
  • Flexible quantities with export packing and shipping managed

Ordering and support

Send drawings, the valve make and model, or worn plates. We confirm material, sealing-face finish and lead time, and can advise on hardfacing to extend service life.

Customized Solutions

Customized according to your operating conditions

High-wear working conditions

For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.

High-impact working conditions

For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.

High-temperature working conditions

For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
