Premium Wear-resistant Spools for Precision Hydraulic Control

Crafted from high-grade alloy steel with chrome plating, these 1-12 spools ensure exceptional durability and smooth fluid flow. Precision CNC machining guarantees tight tolerances (±0.01mm) for leak-free operation in high-pressure systems (up to 350 bar).

Optimized for Agricultural & Industrial Heavy-Duty Use

Specifically engineered for combine harvesters, forestry equipment, and construction machinery. Features hardened sealing edges to withstand abrasive contaminants in hydraulic oil, extending service life by 40% versus standard valves.

Direct OEM Replacement with Enhanced Performance

Interchangeable with major brands" flow control valves (Bosch Rexroth, Parker, Eaton compatible). Includes integrated pneumatic override for emergency manual operation – critical for fieldwork where electrical systems fail.

Bulk Pricing Advantage for Global Suppliers

Wholesale-ready packaging (12 units/box) with competitive MOQ options. Strictly tested under ISO 4406 cleanliness standards (Class 16/14/11). Ships with full technical documentation including pressure-flow curves.

Universal Flow Adjustment Capability

Adjustable orifice design allows precise flow rates from 2-25 L/min without disassembly. Anodized aluminum handle resists corrosion in humid environments while providing tactile feedback during calibration.
