1 Hydro HYDRAULI VALVES A SRONG OMMIMEN O QUALIY Our concept is to sell and deliver the best quality of hydraulic valves, that fully meet our customer s rigorous requirements! o this end, our quality control section is outfitted with sophisticated test equipment. Each valve is subject to comprehensive tests before shipment, including flow, pressure, oil leakage and motion smoothness. What we do is to guarantee that each valve will provide the maximum dependability of performance and minimum trouble for long term operations! Look into these outstanding features: ompact construction. Low pressure drop. Long service life. High efficiency. hoice of various operation methods, such as manual, pneumatic, hydraulic, and electro-hydraulic. hoice of various ports and circuit valves. Spring return. High accuracy spool is hardened for long term accuracy. Sub-plate mounting. Handle shift operation.
