Crusher Accumulator + Head Check & Throttle Valve Assembly

Hydraulic Surge Control Assembly for Single-Cylinder Cone Crushers
Precision Hydraulic Stability | NMS ∙ Metso ∙ Sandvik Compatible

Eliminate hydraulic shock damage and optimize crushing chamber recovery with our integrated Accumulator + Head Check & Throttle Valve Assembly – a critical hydraulic control system engineered for NMS, Metso, and Sandvik single-cylinder cone crushers. This precision assembly ensures smooth piston motion and surge protection in high-intensity crushing cycles.

Key Advantages

Multi-Brand Plug-and-Play: Direct bolt-on replacement for NMS, Metso HP/GP, and Sandvik CH/CS crusher hydraulic circuits.

Zero-Shock Piston Control:

Accumulator: Pre-charged nitrogen (17–20MPa) absorbs hydraulic spikes during tramp events.

Throttle Valve: Adjustable flow control ensures smooth mantle descent (0.5–5 sec adjustable).

Check Valve: Prevents oil backflow during rapid piston retraction.

Extended Component Life: Reduces cylinder/piston fatigue by 60% and prevents hydraulic hose/bladder failures.

Intelligent Chamber Recovery: Maintains consistent CSS during cyclic loading (iron ore, granite).

5-Minute Retrofit: Pre-assembled block with SAE/JIC fittings cuts installation time by 70%.

Extreme Environment Ready: Operates reliably at -40°C to 120°C (-40°F to 248°F) with phosphate ester or mineral oils.

Critical Protection Features

Tramp Iron Defense: Absorbs 500+ kJ impact energy during uncrushable events.

Anti-Cavitation: Maintains positive pressure during piston downstroke.

Contamination Resilience: 25μm filtration tolerance protects valve spools.

Fail-Safe Design: Prevents "mantle bounce" during power loss.

Hydraulic Harmony. Crushing Consistency.
Trust our assembly to transform hydraulic spikes into operational stability – engineered for 100,000+ cycles of zero-failure protection.
