These all in one type Motor Pump and solenoid valves can control not only the direction but also the pressure and flow through many control valves integraded in one manifold. These solenoid valves give advanced features such as compactness, multi-funtions and shockless mechanism, and advance the hydraulic systems to a new stage. This series suited for two or more single-acting cylinders and /or double acting cylinders.

UL recognition has been admitted on AC 115V, DC 12 V, 24V, which proves both of their high quality and safety.

Combined Optimal Circuits
The MS Series incorporates all the valves required for control of speed, pressurem and cylinder stroke direction. Th MS circuit is arranged to provide optimum functions. They are designed to be adaptable to any given system.

Compact, Lightweight Structure and Easy Handling
For the MS2, four solenoid open/close valves, four throttle valves, two checkvalves and one relief valve are all built in one block. The simplifies piping and saves installation space. The aluminium manifold is light in weight and strong.

Shockless Mechanism
The simple mechanism, with the help of oil viscosity, can absorb shocks at stops of operation.

Power Supply

• Confirm that the power volage is correct. Incorrect voltage may cause fire.
• Be careful that continuous operation longer than 10 minutes may burn the coil.

Hydraulic Oil

• Use the pure, anti-wear hydraulic oil with viscosity grade of ISO VG32 or equivalent.
• The oil seal is made of NBR (nitrile rubber). Don not use the hydralic oil containing substances that suffer NBR. Otherwise, failure or trouble may arise.
• It is recommended to replace the hydraulic oil with a new one once a year. Notice that replacing intervals may vary depending on operating conditions.
• Recommended cleanliness : NAS 8 to 9 grade.
• Recommended temperatures : 10

Throttle Vale

• When adjusting the oil flow, close the throttle valve once, and open it gradually for stable oil flow control.
• The throttle valve is fully opened when the MS throttle valve height is similar to that of the main body.
• The throttle valve is fully opened by four turns, starting with the fully closing state. Do not turn further. If the valve is turned excessively or removed, release the pressure first and reattach it in such a manner that O-ring is not damaged.

Relief Valve

• Relief pressure of the MS5 and MS series can be adjusted by turning the adjusting screw at the relief valve. (Counterclockwise turn will reduce pressure.) When adjusting, be sure to use a pressure gauge to keep the pressure within the set pressure range. The setting outside this set pressure range may cause failure or trouble.
