The Hydraforce PV70-33AM-0-N-12DL/W (5120324) is a solenoid-operated, spool-type, normally closed proportional flow control valve. It is designed to work with a pressure compensator to function effectively as a proportional flow regulator. This valve excels in providing precise control due to its excellent linearity and hysteresis characteristics. The valve features a hardened spool and cage for enhanced durability, ensuring long service life. It offers optional coil voltages and terminations, making it adaptable for various applications. The efficient wet-armature construction contributes to the reliable performance of the valve, while the unitized molded coil design ensures standard waterproofing, adding to its robustness in different environments. The PV70-33AM-0-N-12DL/W has pressure ratings of 241 bar (3500 psi) and can withstand proof pressures up to 345 bar (5000 psi) and burst pressures reaching 896 bar (13000 psi). It supports flow rates up to 45.4 lpm (14 gpm), with maximum internal leakage maintained at 197 ml/min (12 in\u00b3/min). The operating fluid temperature ranges from -40\u00b0C to 100\u00b0C with Buna N seals, extending further with other seal options like fluorocarbon or urethane. This makes it suitable for diverse thermal conditions. The valve is compatible with mineral-based or synthetic hydraulic fluids having lubricating properties and supports a fluid viscosity range from 7.4 to 420 cSt. It features corrosion protection capable of enduring up to 960 hours of salt spray per ASTM B117 standards. Installation specifications include a VC10-3 cavity requirement, with cartridge installation torque ranging from 34 to 37 N-m (25 to 27 ft-lb). The PV70-33AM-0-N-12DL/W is versatile with no orientation restrictions during installation, making it an ideal choice for varied hydraulic systems requiring precise flow regulation.
