The Hydraforce PV72-20M-0-N-12ER (5144031) is a high-performance, solenoid-operated, two-port, pressure compensated, spool type, normally closed, proportional flow control valve. This valve is specifically designed to regulate flow out of port 2 irrespective of system working pressure fluctuations. The PV72-20M-0-N-12ER features remarkable linearity and hysteresis characteristics which enhance its reliability and efficiency in various applications. The hardened spool and cage ensure prolonged operational life even under rigorous conditions. This model operates efficiently with a wet-armature construction and offers a manual override option for enhanced control. It supports two regulated flow ranges: up to 64.4 liters per minute (lpm) or 17 gallons per minute (gpm), and up to 37.9 lpm or 10 gpm, catering to different application requirements. The valve's performance is optimized for use with mineral-based or synthetic hydraulic fluids that have lubricating properties within a viscosity range of 7.4 to 420 cSt. The PV72-20M-0-N-12ER can handle pressures up to 240 bar (3500 psi) with proof pressure at 345 bar (5000 psi) and burst pressure reaching up to 896 bar (13000 psi). Its design includes unitized molded coil which is standard waterproofed, enhancing durability in moist environments. Optional coil voltages and terminations allow for flexible configuration according to specific requirements. Additionally, the unit's maximum internal leakage is minimal at only 0.38 lpm (0.1 gpm) at zero current ensuring efficient operation. This model also offers corrosion protection up to 960 hours salt spray per ASTM B117, making it suitable for challenging industrial environments without degradation in performance or safety risks due to corrosion over time.
