Siemens Moore 73N12F Positioner

Description

The Siemens Moore 73N12F is a built-in pneumatic valve positioner designed for precise control in various industrial applications. It operates on a single-axis force-balance principle, ensuring accurate and stable positioning of control valves.

Specifications:

• Instrument Input Pressure Range: 3-15 psig, with options for 3-9, 9-15, and 3-27 psig.
• Supply Pressure: Requires a minimum of 3 psi above the actuator’s necessary pressure, with a maximum limit of 100 psi.
• Air Consumption: Approximately 0.25 SCFM when balanced with a 20 psi supply and a 9 psi dead-ended output.
• Valve Travel: Accommodates strokes from 1/4 inch to 4 inches.
• Ambient Temperature Limits: Operates effectively between -40°F to +180°F (-40°C to +82°C).

Features:

• • Fast Response: The ‘F’ designation indicates a fast response model, suitable for actuators with large volume topworks requiring quick action. Enhanced pilot plunger travel and larger ports provide greater filling and exhausting capacities, resulting in increased valve operation speed.
  • Tapped Exhaust Option: Available for applications using noxious gases as a control medium, allowing pilot exhaust to be safely piped to a designated atmosphere.
  • USM Variant: The ‘USM’ model is tailored for actuators with small topworks and low volume, featuring a special high-response positioner without bleed, ensuring rapid response for precise control.

Applications:

The 73N12F positioner is ideal for controlling valve actuators in processes requiring precise modulation, such as flow, temperature, and pressure control systems. Its robust design and adaptability make it suitable for a wide range of industrial environments.
