7600 Electric Combined Stop/Speed Ratio and Control
The 7600 skid is a drop-in replacement for the 7B-EA & 9E Hydraulic Combined Valve. Made up of the proven 8655 series Stop/Ratio valve and the 3010 series Sonic Flow Gas Control Valve, the 7600 provides superior performance compared to its hydraulic counterpart. The Stop/Ratio valve features a Class VI composite seat, greatly reducing P2 pressure failures and failed starts.
At 1033 lbs., the 7600 is less than half the weight of the hydraulic combined valve and each valve can be independently removed for service. The 7600 is compatible with triple redundant -8 to +8 mA Servo Commands or 4-20 mA Position commands. With a maximum 200ms trip time, the 7600 is 5 times faster than its hydraulic predecessor.
