The Hydraforce PS08-30B-0-N-24/ (5607104) is a direct-acting, spool-type hydraulic sequence valve designed to control the flow of oil to a secondary circuit once a specified pressure level is reached in the primary circuit. This valve features an internal pilot and spring chamber drain, effectively blocking flow at port 1 while allowing flow from port 2 to port 3 in its steady state. When the predetermined pressure at port 1 is achieved, the cartridge shifts to permit flow from port 1 to port 2. Notably, this model's adjustments cannot be backed out of the valve, preventing springs from becoming solid. It offers optional spring ranges up to 165.5 bar (2400 psi), and its hardened spool and cage ensure long-lasting performance within a compact, industry-common size. The PS08-30B model has a pressure rating of 241.3 bar (3500 psi) across all ports, with proof and burst pressures of 482.6 bar (7000 psi) and 896.3 bar (13000 psi), respectively. It supports a flow rate of up to 22.7 lpm (6 gpm) with a maximum internal leakage of 82 ml/min at nominal settings. The valve operates efficiently over a broad temperature range depending on seal material: -40 to 100 \u00b0C with buna N seals, -26 to 204 \u00b0C with viton seals, and -54 to 107 \u00b0C with polyurethane seals. This product accommodates mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains an ISO cleanliness level of up to 18/16/13 for optimal operation. It has an internal wetted surface area of approximately 128 cm\u00b2 for certain models including the PS08-30B and requires no orientation restrictions during installation into VC08-3 cavities using specified torque values between 25.8 and 28.6 N-m (19 to 21 ft-lb). Seal kits are available for maintenance needs under part number SK08-3X-BB.
