The Hydraforce LS04-B30-0-N (5251450) is a load-shuttling, screw-in, cartridge-style hydraulic check valve designed for high efficiency in blocking circuits where flow direction priority is managed between higher and lower pressure circuits. Specifically, it facilitates flow from the higher pressure of either port 1 or port 3 to port 2. This valve finds common usage in directing oil from the pressure side of a bidirectional hydraulic motor to a pressure-released hydraulic brake and can also function as a load-sense signaling valve. The LS04-B30-0-N responds rapidly to changes in load direction and is compact in size, making it suitable for applications where space and quick response are critical. It supports a maximum flow rate of 5.68 liters per minute (1.5 gallons per minute) and can handle pressures up to 241 bar (3500 psi). The valve exhibits maximum internal leakage of five drops per minute at 207 bar (3000 psi), ensuring efficient operation. Temperature resilience is another key feature, with operating fluid temperatures ranging from -40 to +100°C (-40 to +212°F) with Buna N seals, -26 to +204°C (-15 to +400°F) with fluorocarbon seals, and -54 to +107°C (-65 to +225°F) with polyurethane seals. It operates effectively within an ambient temperature range of -40 to +70°C (-40 to +160°F). Hydraforce's LS04-B30-0-N is versatile in its installation options, fitting into VC04B3 cavity types without any orientation restrictions and requiring an installation torque between 5.4 and 6.8 Nm (4 to 5 ft-lb). The valve's robust design allows for a maximum allowable torque of up to 16.3 Nm (12 ft-lb), enhancing its reliability and durability in various hydraulic systems.
