Product Overview
• Brand & Model: HAWE (German hydraulic equipment manufacturer), SG 3 R-AK slide-type directional control valve.
• Product Type: Slide-type directional control valve, a type of hydraulic directional control valve.
• Application Areas: Widely used in industrial hydraulic systems and mobile hydraulic equipment, such as construction machinery hydraulic systems, machine tool hydraulic controls, plastic injection molding machines, metallurgical equipment, and marine hydraulic systems.
Structural Features
• Valve Body Structure: Constructed from high-strength cast iron or steel, featuring precisely machined valve bores and multiple oil passages to ensure pressure resistance and sealing performance.
• Slide Valve Assembly: The core component is a hardened slide valve spool with multiple control edges, surface-ground for optimal sealing. The spool achieves oil circuit switching through axial displacement, thereby controlling the flow direction of hydraulic fluid.
• Actuation Methods: Available with electromagnetic, mechanical, or hydraulic pilot control options to meet diverse application requirements.
• Sealing System: Adopts axial sealing design with high-performance seals to ensure leak-free operation, enhancing system reliability and service life.
Performance Parameters
• Operating Pressure: Capable of withstanding high working pressures (specific values refer to product catalogs or technical specifications, typically reaching several hundred bar), meeting the demands of most industrial hydraulic systems.
• Flow Range: Offers a wide flow range, selectable based on actual requirements to ensure stable hydraulic system operation.
• Temperature Resistance: Operates effectively across a broad temperature range, adapting to various environmental conditions.
Application Advantages
• High-Precision Control: Achieves precise oil circuit switching and flow control through precision-machined spool and valve body structures, improving hydraulic system control accuracy and stability.
• Long Service Life: Utilizes high-quality materials and advanced manufacturing processes to ensure pressure resistance, wear resistance, and corrosion resistance, extending product lifespan.
• High Reliability: Equipped with high-performance seals and an optimized sealing system design to ensure leak-free operation, enhancing system reliability and safety.
• Easy Maintenance: Modular design facilitates quick and convenient disassembly and installation of the valve body, simplifying routine maintenance and upkeep.
