Technical Specifications:
- Maximum Gas Supply Pressure: 750 psig (5170 kPa)
- Fuel Temperature: -40 to +200 °F (-40 to +93 °C) – single resolver; -20 to +200 °F (-29 to +93 °C) – dual resolver
- Ambient Temperature: -40 to +200 °F (-40 to +93 °C) – single resolver; -20 to +200 °F (-29 to +93 °C) – dual resolver
- Input Voltage: 24 VDC
Functional Features: The valve assembly features an on-board electronic controller module for ease of system packaging and installation. The self-cleaning, shear-type metering action keeps the metering port free from performance-limiting deposits. It utilizes a single moving part with the fuel-metering element, actuator rotor, and position feedback resolver mounted on a single solid-piece shaft. It can be configured with single or dual resolver.
Material Composition: Constructed with a highly robust self-cleaning metering valve design and a high-torque actuator.
Structural Features: Conduit entry driver. 1.5 inch SAE Code 61 Flange. Single or dual resolver configuration. On-board driver.
Working Principle: The self-cleaning, shear-type metering action keeps the metering port free from performance-limiting deposits of gas condensates, contaminants, and system debris. The single moving part design integrates the fuel-metering element, actuator rotor, and position feedback resolver on a single solid-piece shaft.
Installation Requirements: The valve assembly features an on-board electronic controller module for ease of system packaging and installation.
Usage Precautions: Ensure the gas supply pressure does not exceed 750 psig. Operate within the specified fuel and ambient temperature ranges based on resolver configuration.
