Electric ash unloading ball valve _ Pneumatic ash unloading ball valve

The following is a comparative analysis of electric ash discharge ball valves and pneumatic ash discharge ball valves, with comprehensive technical parameters, application scenarios, and market data:
1. Comparison of core functions
Features: Electric ash discharge ball valve, pneumatic ash discharge ball valve
Drive mode: motor drive (supports remote/programmable control), compressed air drive (fast response speed)
Applicable media include coal powder, lime, high dust containing fluids with particles, and high-temperature gases (such as coal powder injection)
Sealed design with hard seal (V-shaped sphere, wear-resistant) and double valve stem structure (anti dust accumulation and blockage)
Control accuracy adjustable opening (some models) switch type main (quick opening and closing)
2. Technical parameters
Electric ash discharge ball valve
