Where This Valve Fits
The SD180 is a sectional valve - built from individual sections bolted together into one stack. Each section controls one function.
160 L/min at 315 bar.
If you're looking at the SD8 and wondering if it's enough, the SD180 is probably where you'll end up. It's not the biggest in the SD series, but it's the one that handles most medium-to-large equipment without going all the way to 240 L/min. The extra flow over the SD8 gives you room to breathe - faster cycles, more responsive operation, less waiting.
It's the valve you choose when you know 80 L/min is borderline but 240 L/min is more than you need.
For equipment that fits this flow and pressure range, the SD180 160LPM Manual Sectional Valve is a practical, no-fuss choice.
A Closer Look
160 L/min - What That Gets You
160 L/min moves bigger cylinders at useful speeds. It's for equipment where the operator notices when flow is restricted - where cycle time matters and waiting costs money. The jump from 80 to 160 is noticeable. Not subtle - noticeable.
The pressure rating is 16 MPa nominal, 31.5 MPa max. That's 160 bar continuous, 315 bar peak. Most systems run somewhere in between. The SD180 handles both.
Sectional Construction - Why It Matters
The SD180 is built from individual sections. Each section is its own valve - spool, springs, detent. You bolt them together. Need three sections? Use three. Need six? Add three more. Need to change the machine next year? You can.
This matters because equipment changes. New attachments, new functions, new requirements. With a sectional valve, you don't replace the whole thing. You just add sections.
Oil Requirements
Temperature range: -20°C to +80°C
Viscosity range: 0–400 mm²/s
Filtration accuracy: ≤10 μm
Keep the oil clean and within these ranges, and the valve does its job. The filtration requirement (≤10 μm) is worth paying attention to - dirty oil is what kills valves, not wear.
Where It's Typically Used
Based on its flow rating and sectional construction, the SD180 160LPM Manual Sectional Valve typically ends up on:
Larger Loaders
Boom, bucket, steering, and auxiliary functions. The 160 L/min flow keeps the machine moving fast even with multiple functions running at once. Operators notice the difference when stacking heavy material - the boom comes up without that lag they'd gotten used to.
Excavators
Arm, bucket, swing, travel, and attachments - six sections or more isn't unusual. On a machine like this, cycle time is money. The SD180 moves enough oil to keep everything responsive, even when you're running multiple functions at once.
Harvesters
Header lift, reel adjustment, auger control, and auxiliary hydraulics. Harvest windows are tight - you run until you're done, no breaks. The valve needs to hold up to long days without thermal drift. The SD180 does that.
Presses
Fast approach cycles need high flow. The operator controls the speed directly through the lever, which gives them a feel for the material that no electronic system quite matches. When you're forming metal, that tactile feedback matters.
Marine and Industrial
Winches, cranes, heavy material handling. These systems don't need fancy controls. They need to start, stop, and keep running. The SD180 does exactly that.

FAQ
Q: What is the structure of the SD25?
A: It features a sectional structure with a modular design; each section is cast independently and bolted together to form a complete valve assembly. This configuration offers flexibility, allowing the number of sections to be selected based on specific equipment requirements, while individual sections can be removed and replaced independently during maintenance.
Q: What control options are available for the SD25?
A: Control options include manual, hydraulic, electro-hydraulic, and electronic control. Manual control is suitable for simple equipment, while electro-hydraulic control is ideal for large-scale equipment requiring remote or automated operation; the choice depends on operational preferences and the required level of automation.
Q: What kind of equipment is the SD25 suitable for?
A: The SD25 is primarily used in large construction machinery such as telehandlers, forklifts, all-terrain cranes, excavators, loaders, dump trucks, drilling rigs, concrete pump trucks, and road rollers.
Q: How do I confirm specifications and model numbers when purchasing?
A: The following information needs to be confirmed: number of sections, control method, spool type and configuration, main relief valve pressure setting, port specifications, and mounting dimensions. It is recommended to send the technical requirements and installation drawings to the sales team for verification.
Q: What should be done if oil is seeping between the sections?
A: First, check if the connecting bolts are loose and retighten them to the specified torque. If the bolts are secure but the oil seepage persists, it indicates that the inter-section seal has aged and needs to be replaced.
