RMG AXIAL FLOW VALVE
The standard sleeve, which is the single moving portion, is modeled on Buna N, which is known for its tolerance to different fuel sources and oils and its preservation of physique properties across a wide range of temperatures. Therefore the 70 durometer sleeve was chosen by chance. The code number for the regular 70-strength sleeve is B-7. The 50-strength sleeve, although it is more elastic, is not as rugged as its 70-strength sleeve. The code for 50 durometer is B-5.A single bolt that covers the valve mounting when the middle barrier panel under the tightness screen is finished by the O-ring seal. The cage pressure passages upstream and downstream are secured against the body gallery with roller pin O-ringes. The rollers match the closures of the cage and the valve body. Pressure management (supplied with the pressure of the inlet and equal to it is directed to the sleeve exterior. The differential pressure on the upstream sleeve section is 0 PSi, but the preloading stress is exerted by the sleeve. The difference between the upstream and downstream forces is the downstream part of the sleeve. This differential plus the preload sleeve provides the clamping power. The control pressure must be minimized when the valve is opened. A slight reduction in the pressure control allows the inlet pressure to lift the sleeve from the inlet cage. The central sleeve preload is resolved and the sleeve is pelted away from the downstream cage as the power pressure reduces further. The valve flow starts with the uncovering of the tapered cage openings. Additional decreases in control pressure show a wider outlet cage area. Regulation is retained until the control pressure reaches balance and flux demand is saturated.
