CONVERTS LOW-PRESSURE PORTABLE HYDRAULIC PUMPS OR ON-BOARD HYDRAULIC SYSTEMS, INTO HIGH PRESSURE POWER SOURCES. • May be used to operate two separate, single-acting tools (with integral valves) independently, without need for additional manifold. • Control valve included. Other Power Team valves available as an option to suit your specific application, if needed; consult factory. • Applications include utilities, railroads, construction, riggers and others. • Operates single- or double-acting cylinders, jacks, and tools such as crimpers, spreaders, cable cutters, or tire tools. Version for use with double-acting torque wrenches available. • Compact and rugged for use inside a utility vehicle aerial bucket or stowing in a vehicle. • No reservoir level to maintain; uses low pressure system as oil supply. • Has 3⁄8" NPTF ports; compatible with standard fittings for low and high pressure systems. For use with Cyl. Type Single-Acting Single-Acting/ Double-Acting Double-Acting Order Description No. Hydraulic intensifier for HB443 Valve Type 3-Way single-acting systems 3-Position Hydraulic intensifier for HB444 4-Way double-acting systems 3-Position Hydraulic intensifier for HB445-RR 4-Way double-acting torque 3-Position wrench tools † For maximum efficiency, recommended input flow is 5 gpm at a maximum pressure of 2,000 psi. Higher flows and/or pressures must be compensated for at the system pump (e.g., relief valve, variable flow devices, etc.).
