250L/min 2 Bank Hydraulic Monoblock Directional Valve

Operating Principle:

DF32G.2YK  2 Bank Monoblock Directional Control Valve switches the flow direction of hydraulic oil through the combination and movement of different valve cores. The hydraulic control system drives the valve core to move according to the operation instructions, thereby changing the connection state of the oil port and accurately distributing the hydraulic oil to various actuators, such as hydraulic cylinders, hydraulic motors, etc., to achieve various actions of the equipment, such as lifting, lowering, rotating, and retracting.

Prouduct Features：

This Hydraulic Monoblock Directional Valve is mainly used for large and medium-sized loaders, and can also be used in the hydraulic system of working devices of other large and medium-sized engineering machinery such as bulldozers.

• The pressure-reducing proportional pilot valve control greatly reduces the reversing operating force; improves the micro-motion characteristics of the Hydraulic Monoblock Directional Valve; facilitates pipeline layout and reduces system pressure loss;

• The safety valve, overload valve, oil replenishment valve and one-way valve adopt a plug-in structure, which has good versatility and is easy to maintain;

• Control Mode：Hydraulic Control

• Loop Form：Series Circuit

• Wide flow rate fine-tuning control range, with incremental flow characteristics

• Valve core function: three-position and four-position

• Reasonable design of each throttling groove widens the effective speed regulation area of the Hydraulic Monoblock Directional Valve, improves the micro-motion control characteristics, and has little effect on the valve stem control when the boom is rapidly lowered (at this time, the return flow of the large chamber of the boom cylinder is at high pressure and large flow).
