A high pressure, screw-in, cartridge-style, pilot-operated, proportional spool-type, hydraulic directional valve.
In neutral (unpiloted), the HPE42-M45 allows flow from 2 to 3 bidirectionally. On remote pilot signal at 1, the spool shifts proportionally to the applied pilot pressure to gradually close the flow path until the spool is fully shifted, blocking flow. The spring chamber is vented to port 4. Pressure at 4 will directly (1:1) affect the pilot pressure required and must be added to the bias spring valve.
• Hardened spool and cage for long life.
• Optional sealed pilot.
• Cost-effective cavity.• All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1.• All HyPerformance™ valves are tested at a verification level of 90% and an assurance of 99%.
Operating Pressure: 350 bar (5075 psi); 10% duty cycle 420 bar (6090 psi) Note: All HyPerformance™ products are tested for 900K cycles at 350 bar and 100K cycles at 420 bar.
Proof Pressure: 690 bar (10,000 psi)
