The Hydraforce PV70-30B-0-N-00 (5111002) is a solenoid-operated, pressure-compensated, spool-type, normally closed proportional flow control regulator. This versatile device can function as a priority type regulator or as a restrictive type 2-way regulator when port 2 is blocked. It efficiently manages inlet flow at port 1 by regulating priority flow out of port 3, with the rate being proportional to the solenoid's current input. Excessive flow bypasses through port 2 and can be utilized for auxiliary functions. It features excellent linearity and hysteresis characteristics, a hardened spool and cage for durability, and efficient wet-armature construction. The valve offers optional coil voltages and terminations, standard coil waterproofing, and a manual override option. With an inlet pressure rating of 241 bar (3500 psi), it can handle regulated pressures at ports up to 207 bar (3000 psi). Its proof pressure stands at 345 bar (5000 psi) while the burst pressure reaches up to 896 bar (13000 psi). The valve accommodates a flow rate of up to 49.2 lpm (13.0 gpm) in its maximum input range for three-port configurations. The operating fluid temperature ranges from -40 to 100 \u00b0C with Buna N seals and extends further with other seal options. This product is designed for installation in VC10-3 cavities with specific torque requirements for various components such as cartridge installation torque ranging from 33 to 35 N-m (24 to 26 ft-lb). It supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains corrosion resistance up to 960 hours in salt spray conditions per ASTM B117 standards.
