Woodward Industrial Turbine Fuel Control Valves

Liquid Fuel Control Valves for Gas Turbines

LQ25 Liquid Fuel Control Valve

Woodward’s LQ25 liquid valve platform combines the following in one cost-effective package:

• electrically actuated, rotary fuel control valve
• bypassing regulator
• high speed shutoff valve

The LQ25 is used on industrial and aeroderivative gas turbine engines in the 6,000 to 42,000 kW output power range. The valve incorporates an integral brushless DC limited-angle torque motor to position the control ports. An external DVP (digital valve positioner) is recommended as it accepts both of the position resolver feedback devices, as well as an input command signal.

The valve platform comes with any of three fuel control port sizes (0.1 sq in; 0.2 sq in; 0.3 sq in) to accommodate a wide variety of applications. The integral bypassing regulator is recommended for use with positive displacement pump systems for total system protection. The LQ25 is compatible with most industrial liquid fuels with varying viscosities and lubricity.

Optional features include a pressurizing valve for low downstream manifold systems and an independent shutoff valve with closed limit switches.
