Pratt & Whitney PT6A-27, 28, 34 Series Engines

The Pc Safety Valve™ Kit provides a convenient method of isolating pneumatic pressure and sense lines during engine compressor water rinse and compressor chemical wash operations. The closing of these safety valves prevents water, washing solvents and other contaminants from entering such critical components as fuel controls, governors and bleed valves, and effectively reduces compressor wash/rinse time significantly in all engine applications. All kits feature safety valves that close off each applicable pneumatic line for the specific engine installation, thus eliminating the need for time consuming removal of lines which can lead to pneumatic system failure due to loose lines or cracked or damaged flares. Complete instructions and necessary hardware are included for easy installation.
