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. -
Page 7: Regulatory Compliance
Atmospheres Requirements pertain only to SOGAV™ 2.2 solenoids with the appropriate markings. SOGAV 2.2 solenoids are suitable for use in Class I, Division 2, Groups A, B, C, and D environments, per CSA for Canada and US, or non-hazardous location only. - Page 8 Class I, Division 2, or European Zone 2 wiring methods, and in accordance with the authority having jurisdiction. Wiring for the SOGAV 2.2 solenoid must be suitable for at least 105 °C and at least 10 °C above the maximum ambient temperature.

Tighten these screws evenly to a torque recommended by the engine manufacturer. Install the gas inlet line to the inlet side of the SOGAV 2.2 valve using a Parker O-Lok 6M16F80MLOS fitting or equivalent (per DIN 3852 Part 1). -
Page 14: Chapter 3. Application Guidelines
If the SOGAV valve is used for pre-chamber fuel admission, a check valve must be in place between the pre-chamber and the SOGAV 2.2 valve to prevent backflow of combustion gases. The SOGAV 2.2 valve is capable of 6 bar (600 kPa/87 psi) back pressure without backflow through the valve. -
Page 15: Sizing
Always consult a Woodward application engineer to determine the appropriate system and hardware for the specific application. To determine if the SOGAV 2.2 valve is sized appropriately for an application, use the following methodology: Assuming the full speed and full load condition: Port Injection: Determine the air manifold pressure required to achieve the desired A/F ratio. -
Page 16: Input Power Limitations
Manual 04153 Input Power Limitations Woodward solenoids are labeled with maximum rated values of input current and input power. These input ratings must not be exceeded during continuous solenoid operation, to prevent exceeding a prescribed coil temperature rise at the maximum rated ambient operating temperature. -
Page 17: Chapter 4. Servicing
Driver electronics used Therefore, SOGAV maintenance/reconditioning should be carried out at intervals determined by the engine manufacturer for the particular application. For optimum service/reconditioning, return SOGAV valves to Woodward, where trained personnel and sophisticated reconditioning and test equipment are available. -

2.3 to 2.6 Ω for the MS connector version of the SOGAV 2.2 valve or 2.5 to 2.9 Ω for the cable with gland nut version of the SOGAV 2.2 valve. Because of the low resistance levels, make sure to compensate for the meter lead resistance. - Page 19 Reset the power supply used in the previous test to a 4 A current limit. With no pressure applied to the SOGAV 2.2 valve, turn the switch ON and quickly reduce the current to 1.5 A (the valve can be continually operated at this current level without overheating).
- Page 20 (43.5 psi)? This will prevent valve pull-in. Are the cables and connectors in good condition? Each lead should have less than 0.4 Ω resistance. Have the cables been burnt? Are there intermittent connections at the connectors? Are the connectors tight? Woodward...
