Parker 31055 Tennant Switched Free Flow Hydraulic Sensor Valve

This is a new Parker part number 31055 hydraulic switched/free flow valve with integrated electrical sensor, manufactured for Tennant industrial floor cleaning equipment. The aluminum manifold block features two inline ports — one labeled SWITCHED FLOW (with directional arrow indicating flow-out) and one labeled FREE FLOW (with directional arrow indicating flow-in) — with red port protection caps still installed, confirming new/unused condition. A black compression-fitting cable gland routes the sensor wiring through the block body, terminating in a 3-pin white connector (Molex-style) for integration into a machine control circuit; this sensor output is used to electrically detect or switch hydraulic flow states within the host system. The embossed Parker logo (double-P shield mark) is visible on the block face alongside the part number 31055 and date code 1828 (week 28 of 2018), placing manufacture at a Parker facility. This valve is a direct OEM replacement for Tennant equipment utilizing Parker hydraulic sensor-valve assemblies and is supplied here as new old stock.
