SERVO VALVES

Product catalog summary
Overview: The document provides detailed specifications and features of high-speed linear servo valves, focusing on direct type and two-stage type models. These valves are known for their high response, accuracy, and contamination resistance, making them suitable for various industrial applications.
Specifications: The valves operate at a maximum pressure of 35 MPa (5080 PSI) and are available in different flow rates ranging from 4 to 60 L/min. They feature a low hysteresis of 0.1% or less, ensuring high accuracy and repeatability. The valves are designed to withstand high vibration and contamination levels up to NAS 1638 class 10.
Performance Characteristics: The valves exhibit high response characteristics with a step response time of 2 ms and a frequency response of 450 Hz. These features enable the main unit to achieve high performance and reliability in demanding environments.
Control Methods: The document outlines control methods for both 3-way and 4-way valve configurations, emphasizing the importance of maintaining the specified pressure difference and flow rate relationship.
Model Designation: The document includes a detailed model number designation system, specifying series number, valve size, rated flow, and cable departure direction. Special seals for phosphate ester type fluid are also available.
Additional Information: The document advises consulting Yuken for detailed material such as dimensions and mounting position restrictions. It also provides information on applicable servo amplifiers and protection standards (IP 64).

SERVO VALVES-2

High Speed Linear Servo Valves High-speed linear servo valves have outstanding features of high response and exceptional contamination resistance. These features are achieved by the compact and powerful linear motor which directly drives the spool and gives electric feedback of the spool position. These valves have garnered an excellent reputation since their launch by Yuken in 2001. Direct type LSVG-03 and two stage type LSVHG-04/06/10(which use the LSVG-03 as a pilot) are available. Direct Type High Speed Linear Servo Valves High accuracy These valves have a low hysteresis of 0.1 % or less,...
