The rationality of their configuration directly determines the operating efficiency, energy consumption control and service life of the equipment. This guide strictly follows the requirements of the ISO 9206:2018 international standard (the complete standard and technical details can be found on the ISO official website: https://www.iso.org/standard/73155.html), combines the actual operating conditions of the three major industries, systematically disassembles the selection logic, parameter matching and standard specifications of 3-spool multi-way valves and gerotor motors, and provides a factory-grade configuration scheme that can be directly implemented. It is specially explained for customers, balancing practicality and international compliance, helping overseas equipment manufacturers and technical personnel achieve standardized selection and reduce costs and increase efficiency.
Core Highlights: Strictly follow ISO international hydraulic standards, focus on precise configuration for a single industry, embed exclusive models, integrate foreign authoritative reference materials, support complete parameter tables and high-definition images, balance professionalism and practicality, and accurately match the technical selection needs of overseas equipment manufacturers in the three major industries.

The core design logic is as follows, balancing professionalism and practicality to help overseas equipment manufacturers improve product competitiveness. The structural design and performance optimization of the scheme refer to the hydraulic solutions of Bosch Rexroth (https://www.boschrexroth.com), a global leader in hydraulics.
1. Sanitation Vehicles: HW3-80/21 3-Spool Multi-Way Valve + BMP-160/20 Gerotor Motor
Pressure Matching Logic: The rated pressure of 21MPa is precisely adapted to the mainstream system pressure of 5–12 cubic meter sanitation vehicles in the global market, and complies with the medium and low-pressure hydraulic system pressure specifications in ISO 9206:2018 (for detailed specifications, check https://www.iso.org/standard/73155.html). The peak pressure of 31.5MPa reserves sufficient safety margin to avoid damage to valves and pipelines caused by heavy-duty actions such as garbage compression and bucket tipping.
Flow Optimization Design: The rated flow of 80L/min perfectly matches the output flow of conventional gear pumps for sanitation vehicles, ensuring the response speed of lifting and compression actions, and avoiding energy waste caused by redundant flow, in line with the global energy conservation and environmental protection trend.
Structural Adaptation Advantages: The 3-spool design precisely covers the core actions of sanitation vehicles (lifting + compression + bucket tipping), without the need for additional spools, simplifying the hydraulic system structure and reducing the risk of leakage; the Type O neutral function has good pressure retention performance, avoiding displacement during bucket tipping and compression, and improving operational safety.
Motor Adaptation Highlights: The BMP-160/20 gerotor motor with a large displacement of 160cc achieves low-speed and high-torque output, adapting to the frequent start-stop needs of sanitation vehicle scrapers and sweeping disks. The pollution-resistant sealing structure can effectively resist the erosion of sewage and dust, extending the service life. For similar motor performance standards, you can refer to Parker's official website (https://www.parker.com).
2. Agricultural Machinery: NY3-63/18 3-Spool Multi-Way Valve + BM3-100/18 Gerotor Motor
Pressure and Flow Adaptation: The rated pressure of 18MPa and rated flow of 63L/min are precisely matched to the power output of 50–120 horsepower agricultural machinery, complying with the technical requirements for vibration-resistant hydraulic components in ISO 9206:2018 (refer to https://www.iso.org/standard/73155.html), balancing power and energy saving, and avoiding overheating of the hydraulic system during continuous operation of agricultural machinery.
Neutral Function Selection: The Type Y neutral function can realize pump unloading when the tractor PTO (Power Take-Off) is working, reducing the no-load loss of the hydraulic pump, extending the service life of the pump body, adapting to the long-term continuous operation needs of agricultural machinery, and reducing equipment use costs. For the selection of neutral functions for agricultural hydraulic systems, you can refer to the technical guide on Bosch Rexroth's official website (https://www.boschrexroth.com).
Environmental Adaptability Design: Both valves and motors adopt dust-resistant and vibration-resistant structures, and the seals are made of high and low temperature resistant materials, which can adapt to the complex outdoor operating environment of agricultural machinery (high temperature, low temperature, dust), reduce after-sales failures, and improve equipment reliability.
Implement Matching: The BM3-100/18 motor with a displacement of 100cc and a speed range of 10–750rpm is precisely adapted to the low-speed drive needs of harvester augers, log grabs and other implements, with stable torque output, avoiding implement jamming and insufficient power.
3. Small Loaders: ZL3-90/25 3-Spool Multi-Way Valve + BMR-200/25 Gerotor Motor
Heavy-Duty Adaptation Design: The rated pressure of 25MPa and rated flow of 90L/min comply with the technical requirements for heavy-duty medium and low-pressure hydraulic systems in ISO 9206:2018 (check https://www.iso.org/standard/73155.html for details), adapting to heavy-duty actions such as loading and lifting of 2–3 ton small loaders. The maximum pressure of 25MPa can cope with sudden overload conditions and protect hydraulic components.
Overload Protection Function: The Type O neutral function combined with a bidirectional overload protection device can effectively absorb the impact load during loading operations, avoid damage to hydraulic components caused by overload of the boom and bucket, reduce equipment maintenance costs, and improve operational safety. For the overload protection design of small loader hydraulic systems, refer to Parker's professional solutions on https://www.parker.com.
Versatility Advantage: The 3-spool design covers the core actions of small loaders (boom + bucket + side shift), and reserves auxiliary tool interfaces, which can adapt to the installation of auxiliary tools in different operating scenarios (such as grab buckets, hydraulic breakers), improving equipment versatility and meeting the diverse production needs of overseas manufacturers.
Motor Power Advantage: The BMR-200/25 motor with a large displacement of 200cc and high torque of 620–770Nm is adapted to the walking drive and bucket rotation needs of small loaders, with strong impact resistance, stable power output during walking, and avoiding slipping and insufficient power.
