High-Precision Hydraulic Throttle Valve Z2S Series

Durable Construction
Heavy-duty cast iron body with precision-machined spools for superior wear resistance and long-term reliability in high-pressure systems.
Ultra-Smooth Flow Control
Fine-tuned throttling mechanism ensures steady, adjustable flow rates (Z2S6/Z2S10/Z2S16/Z2S22 models) with minimal pressure drop for hydraulic machinery.
Wide Compatibility
Direct replacement for R900328797 and other OEM codes; integrates seamlessly with industrial equipment like excavators, presses, and agricultural hydraulics.
Optimized Performance
Hardened steel internal components resist corrosion; available in A/B port configurations (e.g., Z2S16-30B) for custom hydraulic circuit setups.
Bulk Savings
Lowest global wholesale pricing for bulk orders—ideal for distributors and large-scale industrial maintenance teams.
Application Scenarios
Ideal for construction machinery, factory automation, and mobile hydraulic systems requiring precise speed/pressure regulation.
