WebA trip will occur (trip valve closes) when two of the three valve sets operate, causing the trip header to drain faster than the control oil supply can refill the header. (+) Big plus side here. Unlike the previous configurations, failure of a single valve will not result in a spurious trip, and will not result in a loss of the safety function . WebSingle trip valve construction reduces costs and spare part requirements of those systems using three separate switching valves to perform the failure functions. A single trip valve greatly simplifies piping requirements. Conversion to any of the fail modes requires only minor hook-up changes. WebThese valves are designed to completely cut off the flow if the turbo compressor encounters a challenge and stops for whatever reason. This automatic shutoff prevents the turbine from over-revving and potentially damaging the equipment. These turbine trip valves, however, need to be specified correctly in order to properly function. gray backpacks for school
