The Hydraforce HS50-42-6TD-P (5241383) is a screw-in, cartridge-style, spool-type, closed in transition, 2-position, 3-way hot oil shuttle valve designed for use with general purpose hydraulic fluids. This valve is specifically engineered to function within hydrostatic transmissions to manage charge pump oil flow either towards a heat exchanger or directly back to the tank. The operation of the HS50-42-6TD-P is characterized by its internal piloting capabilities at ports 1, 2, or 4, which allows for the redirection of oil flow from the port opposite the piloted port to port 3. This action facilitates the removal of oil from the low-pressure side for purposes such as cooling or filtration. This model operates without a spring and depends entirely on internal pilot pressure signals for shifting. It ensures that flow paths remain closed during transitions. The valve can handle pressures up to 245 bar (5000 psi) and operates efficiently within a temperature range of -40°C to +100°C (-40°F to +212°F) with standard Buna N seals. For high-temperature applications, it can accommodate fluorocarbon seals operating from -26°C to +204°C (-15°F to +400°F), and polyurethane and urethane seals from -54°C to +107°C (-65°F to +225°F). The maximum internal leakage is specified at 115 ml/min at a pressure of 207 bar (3000 psi). Additionally, it supports a fluid viscosity range from 7.4 to 420 cSt and can handle maximum operating contamination levels as specified by ISO standards. The HS50-42-6TD-P weighs approximately 0.11 kg (0.25 lb) and has an internal wetted surface area of about 106 cm² (16.4 in²). Installation specifications include a cavity size VC104 suitable for #10 size/4-way cavities with cartridge installation torque ranging between 32.5 to 35.3 Nm (24 to 26 ft-lb). There are no orientation restrictions noted for this unit, ensuring versatile installation options across various system configurations.
