Import Fks Combination Valve Blocks — Buy in Bulk from Supplier in China

The Fks Combination Valve Blocks from Hebei Deneng Trade Co., Ltd are hydraulic control units designed for steering systems in industrial machinery. They feature a compact, integrated manifold structure with multiple directional flow paths, typically constructed from forged aluminum alloy or cast iron, with internal bore tolerances of ±0.05 mm. These blocks are rated for maximum operating pressures up to 250 bar and include standardized SAE J514 port threads for compatibility with common hydraulic fittings.

The valve blocks use standard spool designs with closed-center or open-center configurations, depending on application needs. Surface finishes are typically ground to Ra 0.8 µm to ensure seal integrity and reduce internal leakage. The materials used are chosen for resistance to hydraulic fluid degradation and thermal cycling, aligning with ISO 4406 cleanliness standards for hydraulic systems. These are not generic units but engineered for heavy-duty use in equipment requiring precise pressure modulation.

These valve blocks are commonly sourced by manufacturers of agricultural tractors, construction excavators, and material handling vehicles. Buyers typically require units with integrated pressure relief and bypass features. Trade terms are generally FOB Shijiazhuang or CIF port, with minimum order quantities starting at 50 units. Packaging is in wooden crates with internal foam padding to prevent vibration damage during ocean freight. Buyers should confirm the exact port of loading and required test certificates before placing orders.
