The Hydraforce PV70-30A-0-V-00 (5111001) is a solenoid-operated, pressure-compensated, spool-type, normally closed, priority-type proportional flow control regulator. This versatile valve can also function as a restrictive type, 2-way, pressure-compensated proportional flow regulator when port 2 is blocked. With inlet flow at port 1, the valve regulates priority flow out of port 3 irrespective of system working pressure, with the flow rate directly proportional to the current applied to the solenoid. Excessive flow bypasses through port 2 and can be utilized for auxiliary function control. In applications requiring restrictive mode operation, blocking bypass port 2 ensures that the flow rate out of port 3 remains proportional to the solenoid current regardless of the load applied to port 3. The PV70-30A-0-V-00 features excellent linearity and hysteresis characteristics and includes hardened spool and cage components for durability. It offers optional coil voltages and terminations and incorporates efficient wet-armature construction with voltage-interchangeable cartridges. The valve's unitized molded coil design comes standard with waterproofing and an optional manual override feature. Rated for pressures up to 241 bar (3500 psi) at inlet and regulated pressures up to 207 bar (3000 psi), it withstands proof pressures of 345 bar (5000 psi) and burst pressures of up to 896 bar (13000 psi). The PV70-30A-0-V-00 accommodates operating fluid temperatures ranging from -40\u00b0C to 100\u00b0C with Buna N seals, extending further with other seal materials. It supports mineral-based or synthetic hydraulic fluids within a viscosity range of 7.4 to 420 cSt while maintaining an internal leakage maximum of 197 ml/min at specified conditions. Suitable for diverse applications requiring precise flow regulation under varying loads and pressures, this component is designed for robust performance in demanding environments.
