Product overview
Design and construction
Anti-bias flow design: reduces direct erosion at small openings and is intended to stabilize throttling
Vibration reduction: minimizes the impact of water hammer, particularly near elbows or rapid flow changes, thereby enhancing system safety
Noise reduction: available in single or multi-stage designs to reduce noise levels and comply with strict environmental and workplace standards
Pressure reduction: customizable multi-stage pressure reduction structure to meet on-site working requirements, preventing cavitation and scouring damage
Applications
Coal Chemical Industry: Quench water flow regulation; black ash water flow control; multistage pressure-reducing valves
Salt Chemical Industry: Flow regulation of ash slurry in soda ash production
Mining & Metallurgy: Metal slurries, waste residues
Cement Production: Abrasive slurry handling and flow control
