Description

GE HYDRANM2

Technical Specifications

  • Product Type: Hydraulic Actuator / Positioner
  • Control Signal: Typically 4-20mA or servo valve drive signals
  • Output: Linear or rotary mechanical motion

Functional Features

  • Precise Positioning: Achieves highly accurate valve positioning for optimal turbine control.
  • High Force Output: Generates significant mechanical force to overcome steam pressure and friction.
  • Fast Response: Rapid dynamic response to sudden load changes or trip commands.

Application Scenarios
Steam turbine stop valves, control valves, and fuel gas regulators.

Performance Parameters

  • Resolution: High-resolution positioning for smooth control.
  • Response Time: Millisecond-level response for emergency trip functions.

Material Composition
Heavy-duty machined steel housing, precision-machined spools, and high-performance seals resistant to hydraulic fluid and high temperatures.

Structural Characteristics
Compact, rugged design with integrated LVDT (Linear Variable Differential Transformer) for position feedback and hydraulic port connections.

Working Principle
An electrical signal commands a servo valve, which directs high-pressure hydraulic fluid into the actuator cylinder, moving the piston to the desired position.

Installation Requirements
Must be mechanically linked to the valve with proper alignment. Hydraulic lines must be clean and properly routed.

Usage Precautions
Never exceed the rated hydraulic pressure. Ensure hydraulic fluid is filtered to the required cleanliness level. Bleed air from the system before operation.
