Gas Valves

3103-EM35MR  3103/EM35MR Gas Fuel Control Valve
Woodward’s 3103 control valve is an electric, stainless steel valve for use on DLE and SAC based aeroderivative gas turbines.
Our valve is capable of metering gas flow between 50 and 40 000 lb/hr (23 and 18 144-kg/hr). It is designed to be corrosion resistant and self-cleaning, allowing it to operate in sour gas environments (high sulfur content gas) that can cause problems for other valves. When used in conjunction with an EM35MR actuator and EM 24V digital driver, the 3103 valve delivers the demanding accuracy needed for DLE applications. The EM35MR electric actuator provides a more robust and reliable actuator platform as it eliminates the need for high maintenance hydraulic systems.

Electric-Gas-Metering Electric Gas Metering Valve Gas Control Valve (EGMV)
Woodward’s EGMV (Electric Gas Metering Valve) controls gas fuel flow into the combustion system of an industrial or aeroderivative gas turbine. The valve and all-electric actuator are integrated for precise gas flow under all operating conditions, and is available in either a 2” contoured plug design or a 3” cage valve design. Both sizes provide a linear effective area characteristic that is proportional to valve stroke.
The EGMV is supplied with an integral all-electric actuator that uses a brushless dc motor to drive the valve mechanism. A motor position resolver within the motor assembly acts as the primary motor commutation and actuator/valve position feedback device. This position signal is used by the external Woodward DVP (Digital Valve Positioner) as feedback to properly position the EGMV.
A second resolver is attached to the valve stem and acts as a backup to the primary motor resolver. The actuator portion of the EGMV Gas Control Valve uses a soft stop spring that prevents the actuator from slamming into the minimum stop position in cases of fault detection.

Gas-Stop-Ratio-Valve Gas Stop/Ratio Valve
Woodward’s Rotary Control Valve platform offers a cost-effective, high-speed, pressure control and stop valve in one convenient package.
The pressure regulating capability is achieved by use of a single-acting, spring-loaded hydraulic cylinder that drives a segmented ball valve. The actuator utilizes a triple coil servo valve and dual (or triple) Linear Variable Differential Transformer (LVDT) feedback transducers for applications that require maximum redundancy.
In addition to the pressure regulating feature, the Rotary Control Valve also provides a Class IV (Class VI Optional) shutoff that is sufficiently fast to prevent turbine overspeed in the case of a load rejections. Optional Trip Circuits are available to fit any application.
The Rotary Control valve features a modular design for quick and easy assembly or removal of the valve. Available sizes include 3”, 4”, 6” and 8” valve bodies.

GSOV25-Gas GSOV25 Gas Shutoff Valve
Woodward’s Gas Shutoff Valve (GSOV) platform provides high speed fuel shutoff for emergency and normal shutdown of industrial gas turbines. The valve operates at pressures up to 900 psia (6.2 Mpa) and, with its all stainless steel construction, assures availability of the valve under all operating conditions. The valve design allows minimum pressure drop by utilizing a straight through flow. This also keeps all critical moving parts and seals out of the flow stream.
The GSOV uses line pressure as the primary motive force. A three-way electric solenoid (either 24VDC or 125VDC) acts on an internal piston/spring assembly to operate the valve. Failsafe operation is assured, since the valve is closed when trip voltage is absent.
High temperature and high reverse differential pressure options are available, as required.
