Monoblock Hydraulic Distributor 4P40 Badestnost (Bulgaria)

Product Description: The Badestnost 4P40 monoblock hydraulic distributor is designed for precise control of working fluid flow between a hydraulic pump and actuators (hydraulic cylinders, hydraulic motors). The model features manual control via levers that switch spools into three fixed positions, ensuring ease of operation, convenience, and reliability in mobile and stationary hydraulic systems.

Design Features and Materials: The distributor body is made of EN-GJL300 cast iron, guaranteeing high strength and durability in harsh operating conditions. The plungers (spools) are made of carburized steel with hard chrome plating for increased wear resistance and abrasion resistance. Mounting is done with two M8 bolts, simplifying installation on various types of machines and units.

Application: The 4P40 distributor is widely used in mobile hydraulics — on construction equipment, excavators, loaders, tractor attachments, agricultural machinery, and other units where mechanical control of flow direction and intensity is required. Thanks to its compact monoblock design, the model is easily integrated into hydraulic systems with limited installation space.

These technical specifications make the 4P40 an optimal choice for operators who require ease of control, high reliability, and the ability to withstand a wide temperature range and various types of hydraulic fluids. The cast iron construction and chrome-plated plungers ensure a long service life even under increased loads. The small spool travel of 6 mm, combined with a relatively low actuation force, guarantees clear and predictable operation of levers and handles.

Practical Advantages: The monoblock format reduces the number of connections in the hydraulic system and saves space during installation. Mechanical lever control with three fixed positions allows the operator to quickly change the flow direction and lock the position for safe and comfortable operation.

Typical Applications: Switching flow direction, regulating supply, and blocking circuits on excavators, loaders, tractor attachments, and other mobile equipment where simple and reliable mechanical control is required.
