Electro-Hydraulic Double Plunger Valve
HSX Electro-Hydraulic Double Plunger Valves utilize high-pressure hydraulic cylinders to reciprocate dual solid alloy plungers through precision sleeve bores. Designed for zero-clogging positive cutoff of viscous abrasive slurries, heavy bottom ash, and dense coal water mixtures.

Self-Scraping Positive Displacement Cutoff
Plunger shears through dense slurries and self-cleans on every stroke.
Shearing Positive Displacement
The solid piston plunger shears directly through dense slurries without creating dead flow cavities.
Tungsten Carbide Hardfaced Piston
Plasma-transferred arc tungsten carbide coating withstands millions of abrasive slurry cycles.
Dual-Ring Self-Energized Packing
Spring-loaded PTFE and braided carbon fiber packing ensures zero external leakage along the shaft.
Immense Hydraulic Thrust Drive
High-pressure hydraulic cylinder easily crushes solidified scale and trapped aggregate during closure.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Coal Ash Slurry Pipelines
Power plant bottom ash sluicing trenches, hydraulic ash slurry isolation.
Mining Tailings Disposal
High-density mineral tailings pumping stations, backfill slurry valves.
Alumina Refining Digestion
Bauxite red mud slurry cutoff, precipitation tank isolation.
Coal Chemical Water Slurry
Coal-water mixture preparation tanks, pump intake shutoff.
