Problem StatementReciprocating compressors move large
volumes of natural gas Current compressor valves are reliable but
inefficientInefficiencies caused from indirect flow pathProject Goal: Obtain direct flow with a
rotational type valve
6
Project ScopeMust operate in a rotational manner and obtain
laminar flowOperate at pressures between 30 psi and 600 psiMaterials must be able to withstand temperatures
approaching 350FModifiable to fit all current gas compressors used
by G.E.Is to be easily replacedThe valve is to outperform the volumetric flow rate
of the current plate and poppet valve2000$ budget

Current ProgressParts have been ordered and ready for
pickup: 12”x 12” x 2” , 12” x 12” x 1” , 12” x 12” x ½” Steel plates
Machinist contacted for machining adviceFinal Design changes have been made for
ease of machiningTest rig currently being designed

Future ScopeMachining is to begin next weekTest rig is to be constructed within machining
timeRigorous testing will follow for the remainder
of the semesterDuring testing valve performance will be
optimized
13
Summary3-D prototype already implementedDesign slightly changed for machining
purposes Parts have been orderedMachining is to be started next weekTest rig currently being designedTotal Budget: $2000Total spent: $197.76 Project is running within accepted schedule
