SANY Excavator Proportional Solenoid Valve KDRDE5K-3130C50-122-T

A SANY proportional solenoid valve is a critical component in hydraulic systems, particularly in SANY excavators and other heavy machinery. Here's an overview of its function, features, and importance:

Function of Proportional Solenoid Valve:

1. Hydraulic Control: The proportional solenoid valve regulates the flow of hydraulic fluid in response to electrical signals, allowing precise control over hydraulic actuators such as cylinders and motors.

2. Proportional Control: Unlike on/off solenoid valves, proportional solenoid valves can vary the flow rate proportionally to the electrical input signal. This enables smooth and precise movements of hydraulic components.

Features and Benefits:

1. Precision: Provides accurate and responsive control over hydraulic functions, contributing to precise positioning and operation of equipment attachments.

2. Efficiency: Optimizes energy consumption by adjusting hydraulic flow according to operational needs, reducing heat generation and improving overall system efficiency.

3. Versatility: Suitable for various hydraulic applications, including excavator boom, arm, and bucket movements, as well as auxiliary functions like attachments.

4. Reliability: Designed for durability and reliability under harsh operating conditions, ensuring long service life and minimal maintenance requirements.

Components and Construction:

• Solenoid Coil: Converts electrical signals into magnetic forces that control the valve's opening and closing.

• Spool Valve: Regulates the flow of hydraulic fluid through ports in response to the solenoid's action.

• Pressure and Flow Control: May include features for pressure and flow regulation to maintain optimal hydraulic system performance.
