✅ Description of functions

We present to you a professional two-section hydraulic Directional Valve by PRESKO. Its sturdy monoblock construction guarantees reliability and resistance to high pressures, making it an ideal choice for intensive work in agricultural and construction machinery.

Each of the two control levers operates on the principle of 3-position control on a spring, which ensures intuitive, precise and safe operation cylinderów double-acting.

Operating principle of each lever:

• Position 0 (neutral): The lever automatically returns to this position when pressure is released. In this setting, the hydraulic oil flows freely from the supply (P) to the return to the tank (T), without stressing the pump. Cylinder is locked in the given position, which prevents its accidental movement.
• Position 1 (working / forward, for example): MovinguNIthe lever directs the oil flow from (P) to the working port (A). In the case of cylinder, the piston rod extends. The lever remains in this position only when held by the operator.
• Position 2 (working / e.g. backward): MovinguNIthe lever in the opposite direction directs oil from (P) to the port (B), causing the piston rod to retract cylinder.

The automatic return of the lever to the neutral position is a key safety feature, ideal for controlling attachments that require rapid cycling, such as a front loader (Front loader), grab bale or crocodile bucket.

Hydraulic connections (BSP female threads):

• Pump supply (P): 1/2''
• Return to tank (T): 1/2''
• Outlets to cylinders (A, B): 3/8''
• Series connection (N): 1/2''

✅ Application

UNIversatile design and proven operating parameters make hydraulic Directional Valve 02P40 PRESKO a common choice for machine manufacturers, service shops and individual users alike. It works perfectly in:

• Agricultural machinery: Tractors with front loaders (Front loader), Cyklop type loaders, sprayers, wrappers, orchard machinery.
• Construction machinery: Mini loaders, backhoe loaders, sweepers.
• Forestry machinery: Timber splitters, chippers, winches.
• Industrial applications: Elevators, hydraulic presses and other equipment requiring reliable control.

Why it's worth it

• PRESKO brand: A guarantee of quality and reliability, backed by years of experience in the power hydraulics industry.
• Reliability and long life: Compact, monoblock design made of high-quality cast iron minimizes the risk of leaks and mechanical damage, ensuring trouble-free operation for years.
• System safety: A built-in, adjustable relief valve protects the pump and the entire hydraulic system from the effects of a sudden increase in pressure.
• Versatility: The ability to connect in series with another hydraulic Directional Valve (via ferrule pressure switch) allows easy expansion of the hydraulic system in the future.
• Control precision: Smooth and predictable lever operation allows the operator to have full control over the speed and movement of cylinders.
