WEYO Servo Valves H10 Series 4 Way For Die Casting Machines Injection Molding

Product Specification

WEYO Servo Valve - H10 Series

Overview: The WEYO H10 servo valve is an advanced two-stage electro-hydraulic servo valve, designed for high-performance applications requiring precision and speed. It features a servo-motor-driven pilot stage that controls the main valve core, offering fast response and high accuracy. Ideal for applications such as injection molding machines, die-casting, and other precision control systems.

Key Features:

· Energy Efficiency: The pilot stage reduces leakage by over 70% compared to traditional jet pipe and nozzle deflector pilot stages, significantly lowering the overall valve power consumption.

· High Dynamic Performance: The pilot stage provides excellent dynamic performance, especially with higher pressure gain, which improves response time and stability.

· Superior Static Performance: The valve offers significantly improved static performance with a 5x reduction in hysteresis compared to traditional valve designs.

· Low-Pressure Control: The valve can operate at lower start-up control pressures, enhancing low-pressure performance.

· Built-in Servo Amplifier: The pilot stage integrates a servo amplifier for easy adjustment and maintenance, making it highly customizable for different applications.

· Large Flow Path: The valve body is designed for high-flow capability, with flexible internal control oil options (internal or external control).

Mechanical Installation Interface:
