The snap-action tripping is positive, precise and repeatable. When the turbine shaft exceeds the selected speed the bolt is instantly released to unlatch the trip valve. The bolt is retained until a pre-selected trip speed is reached. The Overspeed Trip Collar, installed on the turbine shaft, houses an adjustable, spring loaded bolt. It is capable of three consecutive non-trending trip-outs within +/-2% of set trip speed. The independent system stops the turbine under any load condition by activating the force-actuated trip valve. Wheel Diameter 12' - 22' Max Power 60 - 1000 HP (44 - 745 kW) Max Speed 4000 - 6000 RPM Max Inlet Pressure 670 - 700 PSIG Max Inlet Temperature 440☌ Max Back Pressure 105 - 165 PSIG Inlet Diameter 3/4' - 4' Exhaust Diameter 3' - 8' RLVA Over-speed Trip System Meets API 611 standards The snap-acting bolt type trip mechanism introduced by COPPUS in the mid 80s set new industry standards for Overspeed Trip Systems.
