Agilent, 5181-7459, Rotor, 6-port, WE series, 400 psi, 225 °C max

The Agilent six-port WE-series rotor is a replacement sealing and switching element for a compatible six-port gas sampling valve used in GC systems. The WE-series operating specifications identify a maximum pressure of 400 psi and a maximum temperature of 225 °C for the matching valve and rotor configuration. Rotor geometry is critical because it defines the internal connections between ports as the valve switches between load and inject positions. Excessive wear, contamination or damage to the sealing face can cause leaks, peak distortion or irregular sample transfer. During maintenance, identify the existing valve series and port count before ordering; a six-port WE-series rotor is not interchangeable with a ten-port WE-series rotor, a WT-series rotor or the rotor installed in some newer valve assemblies. Disassemble only following the valve service instructions, inspect the stator face, and protect the replacement rotor from scratches and debris. Confirm correct indexing, leak tightness and switching operation before validating a chromatographic method. Actual operating conditions must remain within all connected component ratings.
