SD180 Series Sectional Directional Valve
MODEL：SD180 Sectional Directional Valve
APPLICATIONS & FEATURES：
SD180 Series Sectional Valves are simple,compact and heavy duty designed sectional valve from 1 to 12 sections for open and closed center hydralic systems.
Fitted with a main pressure relife valve and a load check valve on every working section.
Avaliable with parallel,series or tandem circuit.
Optional carry-over port.
A wide range of antishock+anticavitation port valves.
Intermediate sectins for several types of circuit.
Diameter 20mm-0.79 in interchangeable spools.
Available manual,pneumatic,elector-hydralic,proportional hydralic,spool control kits.
SD180 series Sectional Valve are widely used in hydraulic systems of engineering machinery, sanitation machinery, mining machinery and other machinery.
OPERATION：
SD180 Series Sectional Valve controls the flow direction and flow of hydraulic oil by moving the valve core, thereby realizing the motion control of actuators (such as hydraulic cylinders, hydraulic motors, etc.). When the valve core is in different positions, the corresponding oil ports are connected or disconnected, so that the hydraulic oil flows along the predetermined path to meet the motion requirements of different working mechanisms. For example, in a crane, the telescopic, luffing and rotation of the boom can be controlled by operating the SD180 Series Sectional Valve; in a loader, the lifting and flipping of the bucket can be controlled.

Application Areas：
Aerial work vehicle: used to control the lifting and lowering of the platform, the extension and rotation of the telescopic arm, etc., to ensure the safety and efficiency of aerial work.
Truck-mounted crane: realizes the extension, amplitude change, rotation and hoisting of the crane arm, and completes the loading and unloading and handling tasks of goods.
Boom pump truck: controls the folding, extension and pumping mechanism of the boom to ensure the smooth transportation and pouring of concrete.
Small loader: controls the lifting, forward and backward tilting of the bucket to realize the shoveling and transportation functions of materials.
Small agricultural machinery: such as small tractors, harvesters, etc., can be used to control the lifting, rotation and other working parts of agricultural tools to improve agricultural production efficiency.
