M250LS directional control valve is designed for tough operating conditions and intended to be used in mobile hydraulic load sensing systems. M250LS is a result of Parker’s wide experience in mobile hydraulics, offering excellent high grade materials and precision manufacturing. M250LS is a monoblock valve with two main spools with the possibility to add up to 4 extra auxiliary L90LS sections.

Good machine design and the right hydraulic system gives a cost-effective installation, which in turn gives a competitive product. The pump and workports in the M250LS are arranged in such a way that hosing and piping can be kept to an absolute minimum. The valve is equipped with double workports at 180°, which eliminates T-connectors and gives the shortest and simplest path to the cylinders. This also enables dimensions to be kept small, since only half the flow passes through each service port.

The M250LS is of robust construction. Many of the components are of the cartridge or module types, which makes servicing easy. It has both spool and poppet elements that give double safety in the case of hanging loads. The valve is also extremely well sealed, which prevents unintentional load sinking.

M250LS can be actuated hydraulically and electro-hydraulically and is equipped with possibility of forth position float function.

Markets:
• Construction Equipment
• Material Handling Equipment
• Mining

Features/Benefits:
• Excellent sealing: work ports closed by means of poppet valves.
• Not sensitive to temperature shocks: poppet-valve concept gives relatively large clearance between main spool and bore.
• Good energy efficiency: low pressure drops for high function speeds; low energy consumption.
• Easy to install: designed with simple installation in mind.
• Stackable up to 4 auxiliary functions.
• Optional float-position function: built-in, pressure-controlled float-position function eliminates the need for external components and signals.
• Great precision: low hysteresis gives precise control and good operator comfort.
• Pressure compensated lift and lowering functions
• Easy to service
• Long service life: efficient port-relief and anti-cavitation valves reduce the number of pressure peaks and cavitation in the system, thus prolonging the life of the machine.
• Quality materials and great precision in manufacturing, assembly and test to ensure that you will get a quality product with low internal leakage and long service life.

Applications:
• Wheel Loaders
• Fork lift trucks
• Mining Loaders
• Reach stackers
