The Hydraforce PV08-30A-0-N-12ER (Material Number: 5110526) 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. With an inlet flow at port 1, the valve regulates priority flow out of port 3 regardless of system working pressure, with the flow rate being proportional to the current applied to the solenoid. Excessive flow bypasses out of port 2 and can be used for auxiliary function control. In restrictive mode applications where bypass port 2 is blocked, the flow rate out of port 3 remains proportional to the solenoid current regardless of load pressure applied at port 3. The PV08-30 features excellent linearity and hysteresis characteristics and includes a hardened spool and cage for long life. It offers optional coil voltages and terminations with efficient wet-armature construction. The valve supports a maximum inlet pressure rating of 241 bar (3500 psi), regulated and bypass pressures up to 207 bar (3000 psi), proof pressure of 345 bar (5000 psi), and burst pressure up to 896 bar (13000 psi). Flow ratings include regulated ranges from 5.7 lpm to a maximum input range of up to 22.8 lpm. Temperature ratings for operating fluid range from -40 to +100 \u00b0C with Buna N seals or -26 to +204 \u00b0C with fluorocarbon seals. The valve's environmental capabilities include corrosion protection tested up to a 960-hour salt spray per ASTM B117 standards. Installation specifications require a VC08-3 cavity with cartridge installation torque between 25.8 and 28.5 N-m. This product is suitable for use with mineral-based or synthetic hydraulic fluid within a viscosity range of 7.4 to 420 cSt, ensuring optimal performance in various hydraulic systems requiring precise flow control regulation.
