The Hydraforce PV70-30BM-0-N-12DL/W (5111048) is a solenoid-operated, pressure-compensated, spool-type, normally closed, priority-type proportional flow control regulator. It can also function as a restrictive type, 2-way, pressure-compensated proportional flow regulator when port 2 is blocked. Designed for precise flow control applications, the valve regulates priority flow from port 1 to port 3 regardless of the system's working pressure, with the flow rate being proportional to the current applied to the solenoid. Excessive flow is bypassed through port 2 and can be utilized for auxiliary functions. The valve features excellent linearity and hysteresis characteristics and includes hardened spool and cage components for extended durability. Optional coil voltages and terminations are available, along with efficient wet-armature construction and standard coil waterproofing. The PV70-30 offers a manual override option for additional control flexibility. The valve's pressure ratings include a maximum inlet pressure of 241 bar (3500 psi), regulated pressures at ports up to 207 bar (3000 psi), proof pressure of 345 bar (5000 psi), and burst pressure of 896 bar (13000 psi). It supports various flow ratings depending on configuration: up to 26.5 lpm regulated in a two-port setup or up to 49.2 lpm maximum input in a three-port setup. The valve operates efficiently over fluid temperatures ranging from -40\u00b0C to +204\u00b0C depending on seal material used and maintains corrosion protection with a salt spray rating of up to 960 hours per ASTM B117 standards. Additional specifications include an internal leakage rate of up to 197 ml/min at specified conditions, fluid viscosity range from 7.4 to 420 cSt, maximum operating contamination level per ISO standards, and specific torque requirements for installation components such as the cartridge installation torque range of 33-35 N-m.
