Cone Valves
Product Description :
PUTECH flotation cone valves are cast with imported polyurethane, resistant to abrasion, impact and flotation reagent corrosion. They withstand long-term slurry scouring, particle friction and acid-base erosion, outperforming standard rubber & metal spare parts by a large margin. Excellent material toughness delivers stable sealing during opening/closing without leakage or jamming, precisely controlling slurry flow for consistent flotation system operation.
Specifications
Vulnerable Zones & Failures
1. Sealing cone surface: Wear/deformation → ore leakage and unstable liquid level, reduced recovery
2. Cone spool & seat edges: Erosion & chipping → sealing failure, local vortex and accumulated sediment
3. Valve stem joints: Vibration abrasion → looseness, uneven wear and valve sticking
Inspection & Replacement Standard
Inspection Cycle: 500–1,000 working hours; check cone surface abrasion, sealing integrity and valve stem flexibility
Replacement Criteria:
1. Sealing surface abrasion ≥2mm or deep grooves/cracks form
2. Ore leakage rate ≥5% or liquid level cannot be stabilized
3. Severe deformation or material shedding on spool/valve seat
Maintenance Tips
Avoid iron blocks & bulk debris impact; regularly clean cone surfaces to prevent mineral scaling; maintain coaxial installation with uniform gaps for balanced wear.
