Product Introduction

DCV140 Series Sectional Directional Hydraulic Pump Control Valve

The precise control center of the hydraulic system

In the field of industrial hydraulics and construction machinery, the power output of hydraulic pumps needs to be "distributed on demand" through precise control components - whether it is the multi-stage pressure regulation of injection molding machines or the compound action coordination of excavators, they all rely on the real-time control of oil flow direction, pressure and flow rate by control valves. The DCV140 Series Sectional Directional Hydraulic Pump Control Valve is precisely the core control component designed for this purpose. It is based ona sectional structure and integrates directional control and pump control functions. It can provide stable and efficient control support for various hydraulic systems. As a professional hydraulic pump control valve, its modular design can flexibly adapt to systems of different complexities, becoming the key to improving the operational accuracy and running efficiency of the equipment.

Core advantages: Dual highlights of precise control and flexible adaptation

Multi-dimensional flow control and sensitive action response

The core value of hydraulic pump control valve lies in the precise allocation of hydraulic power, and the DCV140 series performs outstandingly in this field: It can simultaneously achieve directional switching (reversing time ≤0.2 seconds) and flow regulation (regulation accuracy ±2%). When the hydraulic pump outputs high-pressure oil, the valve can quickly guide the oil flow to the target actuator and control the flow rate according to the action requirements. For example, in the operation of the hydraulic robotic arm in the automated production line, the DCV140 hydraulic valve can precisely control the amount of oil flowing into the cylinder of the robotic arm, ensuring smooth and shock-free grasping and handling actions, and the position error is controlled within ±0.5mm.

This multi-dimensional control capability is particularly important in multi-action collaborative scenarios. Take the compound action of "lifting + bucket turning" of the loader as an example. The hydraulic pump control valve can simultaneously adjust the oil flow distribution of the two actuators, avoiding action lag caused by power competition, making the operation smoother and increasing the operation efficiency by 15%.

Fragmented design, compatible with diverse systems

The DCV140 hydraulic valve adopts a segmented structure. Each functional module (such as the direction control plate, flow regulation plate, and pressure compensation plate) can be freely combined according to the actual requirements of the hydraulic system. If the system only requires single-pump single-action control, the basic control module can be selected. If it is necessary to adapt to a dual-pump and dual-loop system, only the corresponding sections need to be added, without the need to replace the entire valve body. This flexibility not only reduces the initial configuration cost but also provides convenience for later system upgrades - for instance, when new auxiliary actions need to be added to the equipment, functional shards can be directly installed without the need to reconstruct the control loop.

Meanwhile, the segmented structure makes maintenance more efficient: when a certain module malfunctions, it can be disassembled and replaced separately, reducing the maintenance time by 60% compared to integral valves and significantly minimizing equipment downtime losses.

Technical features: Tailor-optimized for efficient control

High-pressure endurance capacity: The valve body is made of high-strength ductile iron, with a working pressure up to 315bar and a peak pressure resistance of 400bar instantaneous impact. It is suitable for medium and high-pressure hydraulic pump systems and maintains stable performance in heavy-load operations of construction machinery.
Low-resistance flow channel design: The internal oil passage is optimized through CFD simulation, reducing flow resistance by 10% and minimizing hydraulic energy loss. Combined with the precise regulation of the hydraulic pump control valve, the overall energy efficiency of the system can be increased by 8-12%.
Anti-pollution structure: The valve core and valve hole are designed with gap sealing and wear-resistant coating, which can withstand ISO 18/15 grade oil contamination. In a construction site environment with a lot of dust, the service life is 30% longer than that of ordinary valves.
Compatible with multiple media: It can be adapted to commonly used hydraulic media such as mineral oil and water glycol, eliminating the need to replace valves based on the type of medium and enhancing its applicability in various industrial scenarios.

Product Description

Model DCV140 Dimensional Data

The detent structures include twe forms:spring centred spool&without spring centred spool. Spring centred spool have those several structures:detent in A,detent in B,detent in A and B,detent in A,B and 0. Without spring centred spool only have one structure: detent in A,B and O.We can made the products inaccordance with particular instructions or requirements of the customers. The application of electrohydraulic control and handle control have a lot of combination.In the catalogue,we give you only one example of them. We can made the prodacts in accordance with particular instructions or requirements of the customers. For example:right inlet section. 12V or 24V. etc. You should present the status pressure and flow before the order.For us to debugg the valves before the conslgnment. We suggest that when you choose the valve please refer to our sellor or technical adviser.

Please tell us the data of the hydraulic remote control when you order it.The normal pilot pressure is 5~ 30 bar.When you have special requirment please tell our technical adviser.
