Product Specifications

Technical details and manufacturing context for Regulating Valve (Actuator)

Definition
A critical component within the Pressure Regulation Module that precisely adjusts valve opening to regulate fluid pressure, flow rate, or other process variables by converting control signals into mechanical motion.
Working Principle
Receives electrical, pneumatic, or hydraulic control signals and converts them into mechanical force to position the valve stem, thereby adjusting the flow area through the valve to achieve desired regulation of pressure or flow.
Common Materials
Stainless Steel, Aluminum Alloy, Engineering Plastics
Technical Parameters
  • Valve port diameter or actuator stroke length (mm) Customizable
Components / BOM
  • Motor/Drive Unit
    Converts electrical energy into mechanical motion
    Material: Copper windings, steel housing
  • Gear Reduction System
    Increases torque output while reducing rotational speed
    Material: Hardened steel gears
  • Position Sensor
    Monitors and reports valve position to control system
    Material: Electronic components, plastic housing
  • Housing
    Protects internal components from environmental conditions
    Material: Aluminum alloy or stainless steel
Engineering Reasoning
0.5-20 bar differential pressure, -40°C to 120°C ambient temperature, 4-20 mA control signal
25 bar differential pressure causes diaphragm rupture, 150°C ambient temperature degrades elastomer seals, 30 mA control signal overloads positioner electronics
Design Rationale: Diaphragm material yield strength (EPDM rubber: 15 MPa tensile) exceeded at 25 bar differential pressure; Arrhenius degradation of nitrile seals accelerates above 150°C; MOSFET junction temperature exceeds 175°C at 30 mA due to I²R heating
Risk Mitigation (FMEA)
Trigger Water ingress into positioner housing due to IP65 seal degradation
Mode: Hall effect sensor corrosion causing position feedback loss
Strategy: Hermetically sealed sensor compartment with welded stainless steel enclosure and desiccant pack
Trigger Pneumatic supply contamination with 5 μm particulate exceeding ISO 8573-1:2010 Class 3
Mode: Spool valve stiction leading to 2-second response delay
Strategy: Integrated 40 μm filter with differential pressure indicator and automatic purge valve

Frequently Asked Questions

What industries commonly use this regulating valve actuator?

This actuator is designed for machinery and equipment manufacturing, including applications in industrial automation, process control systems, fluid handling equipment, and manufacturing lines where precise fluid flow regulation is required.

How does the position sensor improve valve control accuracy?

The integrated position sensor provides real-time feedback on valve position, enabling precise adjustment to control signals. This ensures accurate flow regulation, reduces overshoot, and allows for closed-loop control systems in industrial applications.

What maintenance is required for the gear reduction system?

The gear reduction system requires periodic lubrication according to manufacturer specifications, inspection for wear every 6-12 months depending on usage intensity, and protection from contamination. Stainless steel and aluminum alloy construction minimizes corrosion-related maintenance.
