The Hydraforce HLS06-B30 (5251460) is a high-performance, screw-in, cartridge-style hydraulic check valve designed for blocking circuits where flow direction priority is given to the higher pressure circuit over a lower one. This model allows fluid flow from either port 1 or 3 to port 2, adapting rapidly to changes in load direction. The HLS06-B30 boasts a higher flow capacity and lower pressure drop, optimizing hydraulic efficiency while maintaining a compact footprint suitable for space-constrained applications. This valve features impressive durability with a cycle life of one million cycles and robust pressure ratings: 350 bar (5075 psi) operational and up to 690 bar (10000 psi) proof pressure, with a burst pressure reaching 1380 bar (20000 psi). It supports fluid temperatures ranging from -40°C to +100°C with Buna N seals, and even wider ranges with other seal types such as Viton and urethane. Flow capabilities are set at 7.6 lpm (2 gpm), with maximum internal leakage meticulously controlled at just about two drops per minute at full operational pressure. The HLS06-B30 is compatible with mineral-based or synthetic hydraulic fluids within a viscosity range of 7.4 to 420 cSt and can operate effectively even under maximum contamination levels specified by ISO 4406 standards. Its lightweight design (0.02 kg) and minimal internal wetted surface area ensure efficient operation without excess bulk. Installation specifications include an HVC06b3 cavity requirement, with no orientation restrictions and a recommended cartridge installation torque of approximately 11.0 Nm for steel/ductile iron cavities. Optional accessories such as various seal kits tailored for different temperature and environmental conditions are available, ensuring versatility across numerous applications without compromising performance integrity.
