Key features

Integral monoblock ductile cast iron body with compact structure, excellent pressure bearing and impact resistance, and avoids oil leakage under long-term high-pressure working conditions.

Independent 2-spool control design: each lever controls one hydraulic circuit separately, realizing flexible and accurate action control for hydraulic cylinders and motors.

The lever, equipped with a dustproof rubber boot, effectively blocks dust and impurities from entering the valve interior, extends service life, and adapts to harsh outdoor working environments.

Built-in adjustable relief valve supports flexible system pressure setting, provides reliable overpressure protection for the whole hydraulic system, and improves operational safety.

Precision-machined spool with tight fit clearance, low internal leakage, and stable and smooth commutation performance ensures stable action of hydraulic actuators.

Standard threaded oil ports with universal dimensions, easy to connect with standard hydraulic hoses and fittings, convenient for on-site installation and later maintenance.

High-performance NBR oil-resistant seals, with good wear and aging resistance, maintain stable sealing performance under long-term frequent high-pressure operation.
