IC3600SSVG1C1B New-Surplus Servo Valve Drive Card

Offered here as new-surplus, no-box stock with a one-year warranty, this IC3600SSVG1C1B is an unused servo valve drive card for GE Mark I and Mark II Speedtronic turbines. For sites still running IC3600 hydraulics, an unused valve-drive board on the shelf can be the difference between a quick recovery and a long outage.

Closed-Loop Valve Positioning in the Mark I-II Speedtronic

The SSVG sits at the sharp end of the servo loop. Its task is to accept a low-level valve-position command from the turbine control and deliver the electrical drive that moves the servo valve, while a feedback device typically an LVDT reports where the valve actually is. The card keeps adjusting its output until commanded and actual positions match. This is the mechanism behind steady fuel or steam metering, and therefore stable speed and load control, on these early Speedtronic machines. GE labels the board "SRVO. VALV. DRV," and supplier cross-references tie the fuel servo valves to the SSVF and SSVG cards.

Diagnostics: Confirm the Loop Before Ordering a Drive Card

Even when you intend to buy an unused spare, confirm that the card in service is truly at fault servo symptoms are deceptive:

• Open feedback drives the valve to a stop. A failed LVDT or broken feedback wire removes the loop's position reference and pushes the output hardover. Inspect the feedback path and SSVF before the drive card.
• Coil and valve. Test the servo valve coil resistance and continuity.
• Hydraulic health. Verify supply pressure, filtration and return; contamination causes hunting and slow response.
• Reference and null. Check the incoming command and the null and bias set-up.
• Power and seating. Confirm the DC supplies and reseat the board after cleaning the edge fingers.

A spare SSVG is cheap insurance; installing one for a hydraulic or feedback fault is not a fix.

Full Part-Number Match for New-Surplus SSVG Stock

This board is IC3600SSVG1C1B: the SSVG function code with the 1C1B variant and revision. Because the servo group's fourth letter changes the function (A, B, E, F, G and J are different cards), and the trailing dash identifies the revision, confirm the entire number against your installed unit. The GE Speedtronic Part Number Decoder details each field.

Servo Chain: Which IC3600 Cards Surround the SSVG

In the servo chain the SSVG is bracketed by the SSVF feedback card and the SSVA and SSVB servo cards, with analog reference and power-supply boards nearby. For matched components, see our GE Mark I-II IC3600 Cards collection and the full GE Speedtronic Turbine Control Boards range.
