Battery Charging
Device
To prevent damage to a control system that uses an alternator or
battery-charging device, make sure the charging device is turned off
before disconnecting the battery from the system.
Electrostatic Discharge Awareness
Electrostatic
Precautions
Electronic controls contain static-sensitive parts. Observe the
following precautions to prevent damage to these parts:
Discharge body static before handling the control (with power to
the control turned off, contact a grounded surface and maintain
contact while handling the control).
Avoid all plastic, vinyl, and Styrofoam (except antistatic versions)
around printed circuit boards.
Do not touch the components or conductors on a printed circuit
board with your hands or with conductive devices.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual
82715, Guide for Handling and Protection of Electronic Controls,
Printed Circuit Boards, and Modules.
Follow these precautions when working with or near the control.
1. Avoid the build-up of static electricity on your body by not wearing clothing
made of synthetic materials. Wear cotton or cotton-blend materials as much
as possible because these do not store static electric charges as much as
synthetics.
2. Do not remove the printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the control
cabinet, follow these precautions:
Do not touch any part of the PCB except the edges.
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.

General Information
Safety Considerations
The shutoff valve is a critical component for protection against
equipment failure and turbine overspeed. Routine inspection is
necessary for the protection of the turbine and/or the turbine
operators.
The shutoff valve is designed to protect the turbine should the
normal fuel control become inoperative for any reason. Critical
overspeed may occur should the valve fail to shut off fuel to the
turbine. Engine overspeed can cause serious mechanical damage as
well as personal injury or death.
Always use the shutoff valve to stop the turbine. This exercise provides proof of
the proper operation of the safety equipment.
Because of the critical function of the valve, it is mandatory that the operator
regularly monitor the valve whenever the turbine is shut down, as well as during
normal operation.
While the valve is closed, check for excessive leakage, either through the valve
or through the vent. Any leakage through the valve to the turbine should be
considered proof of wear and/or possible malfunction. The valve should be
immediately replaced and returned for factory service.
A minimal amount of leakage can be expected through the bypass connection of
the valve. Should the volume of leakage change appreciably, the valve should be
replaced and returned to a service facility.
Woodward recommends the installation of two shutoff valves per API-616.
Shutoff Valve Description
The Woodward High Speed Liquid Fuel Shutoff Valve is a three-way, two-stage
valve, designed to provide fuel bypass in 0.090 seconds or less after termination
of the solenoid current. Loss or termination of the electrical signal will result in all
fuel delivery to the valve being bypassed to the return system.
The valve is compatible with most liquid fuels, including diesel fuel, methanol,
ethanol, Jet "A", kerosene, #2 home heating oil, heated light crudes, and
residuals. The valve will accommodate contaminated fuels within prescribed
limits.
An inlet screen in the valve prevents contaminants in excess of 40 µm (nominal)
from damaging the pilot-valve section.
The shutoff valve housing is constructed of anodized aluminum. All moving
internal parts are hardened stainless steel.

Installation
Receiving
The liquid fuel shutoff valve is tested with a non-corrosive liquid, drained and
packed in a foam-filled box for shipment. The unit may be stored for an extended
period in the original container.
Mounting
The valve is designed for installation in any attitude with two 3/8 inch or M10
bolts. (See the outline drawing, Figure 2-1, for location of the mounting holes and
of the valve.)
1.625 inch (-20) straight thread ports are provided for inlet, bypass and outlet
pipe connections. The bypass plumbing must be of equal size to the inlet and
unobstructed to assure positive shutoff by the valve.
Electrical
A 0.500 inch-14 NPTF conduit adapter and 10 ft (3 m) leads of shielded wire are
provided for the electrical connection. Connect the proper voltage to the two
wires extending from the conduit connector (see the outline drawing). Polarity is
not important.
Maintenance
Recommended: Disassembly for cleaning and inspection every 10 000 cycles or
3 years of operation, whichever occurs first. In case of contamination of the
interior passages, the valve may be disassembled and cleaned in the field by a
trained service technician.
Routinely check the shutdown switches or relays to be sure they are capable of
interrupting the electronic signal to the shutoff valve.
Always use the valve for routine shutdown as a check for continued
operation.

Chapter 3.
Principles of Operation
Figure 3-2 illustrates the operating principle of the shutoff valve.
The shutoff valve is designed to be the last element in the fuel-supply line to the
turbine. Its rapid closure time of less than 1/10 second, and opening time of 4/10
second, makes it an ideal valve for both routine and emergency shutoff of the
fuel supply to the controlled device.
The valve is either full on or sealed tightly off. In the full on (valve energized)
mode, a small amount of leakage will occur to bypass. Termination of the
electrical signal will result in all fuel delivery to the valve being bypassed to the
fuel return system.
Fuel pressure and flow must be present to ensure proper operation of the valve.
Springs on the control plunger in the valve will cause the valve to close itself
should the fuel flow drop below a nominal amount.
The regulator generates a working pressure within the valve. In the de-energized
state, the working pressure supplements the return spring force on the shuttle
piston to provide a positive no-leak seal at the turbine fuel manifold. This ensures
rapid shutdown capability and prevents nozzle contamination when dual-fuel
turbines are operated on gaseous fuel.
When energized, the first-stage solenoid valve directs fuel pressure to the top of
the control piston (C2). The pressure drives the control piston down. This closes
the bypass port and drives the shuttle piston away from the seal, opening the fuel
passage through the valve to the turbine.
As soon as fuel system pressures reach 50 psi (345 kPa) or more, the regulator
piston opens completely. This results in a minimum pressure drop through the
valve and assures that maximum fuel flow can go through the valve.
When the electrical signal is removed from the solenoid, inlet pressure is directed
below the shuttle piston. Simultaneously, the pressure on the control piston is
vented to bypass. The combination of spring pressure and fuel pressure then
drives the shuttle piston against the seal.
A 40 µm wash-flow filter is provided between inlet pressure and the solenoid
control valve to assure trouble free operation of the shutoff valve. The valve
provides no filtration for the fuel flowing to the turbine or to bypass. In the shutoff
position all inlet flow is directed to bypass. This prevents buildup of pressure in
the positive-flow fuel system which could cause damage to the pump or
plumbing. For optimum dynamic response, it is important that the bypass fuel
plumbing be sized large enough to accommodate the maximum expected pump
delivery with less than 50 psi (345 kPa) head measured at the valve bypass port.
Also, inlet pressure should be at least 50 psi (345 kPa) higher than bypass
pressure in all operating conditions.
Polarity is unimportant in the dc-operated valve.
The maximum power consumption of the valve is 15 W.
A bipolar zener diode is provided in the solenoid wiring to prevent voltage spikes
during operation and to prevent the generation of electromagnetic interference
(EMI).

Woodward Factory Servicing Options
The following factory options for servicing Woodward products are available
through your local Full-Service Distributor or the OEM or Packager of the
equipment system, based on the standard Woodward Product and Service
Warranty (5-01-1205) that is in effect at the time the product is originally shipped
from Woodward or a service is performed:
Replacement/Exchange (24-hour service)
Flat Rate Repair
Flat Rate Remanufacture
Replacement/Exchange: Replacement/Exchange is a premium program
designed for the user who is in need of immediate service. It allows you to
request and receive a like-new replacement unit in minimum time (usually within
24 hours of the request), providing a suitable unit is available at the time of the
request, thereby minimizing costly downtime. This is a flat-rate program and
includes the full standard Woodward product warranty (Woodward Product and
Service Warranty 5-01-1205).
This option allows you to call your Full-Service Distributor in the event of an
unexpected outage, or in advance of a scheduled outage, to request a
