Description

The GS-Series is an electrically actuated fuel valve with an on-board electronic

driver. The self-cleaning, shear-type metering action keeps the metering port free

from performance-limiting deposits of gas condensates, contaminants, and system

debris. The valve minimizes the moving parts within the fuel metering element,

actuator rotor, and redundant position feedback resolvers to maximize accuracy over

the entire operating range. Available actuator torque has been increased to provide

more robust performance in the harshest conditions. Accurate flow versus input

signal characteristics is achieved on each valve version by precision forming of the

valve metering port, the use of extended valve travels, and high precision resolvers

for valve position feedback. The GS valves can achieve flow turn-down ratios in

excess of 100 to 1. The positive flow shut-off rating meets the requirements of ANSI

B16.104 Class IV across all valve sizes and ports.
