HS50-42

HOT OIL SHUTTLE VALVE

Overview

Description

The HS50-42 is a screw-in, cartridge style, spool type, closed in transition, 2-position, 3-way hot oil shuttle valve for use with general purpose hydraulic fluids. The valve CAN be utilized on hydrostatic transmissions to direct charge pump oil to a heat exchanger or to tank

Operation

With internal piloting at port 1, 2 or 4, the s50-42 will direct oil flow from the port opposite of the port piloted to port 3, thus removing oil from the low-pressure side for cooling or filtration purposes. The valve is springless, relying solely on the internal pilot pressure signal to shift to either side. Flow paths are closed in transition.
