The Hydraforce PV70-33A-0-N-00 (5120000) is a solenoid-operated, spool-type, normally closed proportional flow control valve designed to function as a proportional flow regulator when used with a pressure compensator. This robust valve features excellent linearity and hysteresis characteristics, ensuring precise flow control. The hardened spool and cage contribute to its long life, while the unitized, molded coil design with standard waterproofing enhances durability in various environments. It offers flexibility with optional coil voltages and terminations and efficient wet-armature construction. The valve is capable of handling pressure ratings up to 241 bar (3500 psi), proof pressure of 345 bar (5000 psi), and burst pressure of 896 bar (13000 psi). It supports flow rates ranging from 0 to 45.4 lpm (0 to 14 gpm) across different ranges and maintains a maximum internal leakage of 197 ml/min (12 in\u00b3/min). Suitable for diverse operating conditions, it can function within an operating fluid temperature range of -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) with urethane seals. The PV70-33A-0-N-00 also boasts corrosion protection rated at 960 hours salt spray per ASTM B117 standards. It is compatible with mineral-based or synthetic hydraulic fluids having viscosities from 7.4 to 420 cSt. Installation specifications include a VC10-3 cavity size and torque requirements for cartridge installation ranging from 34 to 37 N-m (25 to 27 ft-lb). With no orientation restrictions and available accessories like seal kits and various coil options, this valve provides versatile application possibilities in hydraulic systems requiring reliable flow regulation.
