A high pressure, screw-in, cartridge-style, pilot-operated, proportional spool-type, hydraulic directional valve.
In neutral (unpiloted), the HPE42-M44 blocks flow from 2 to 3 bidirectionally. On remote pilot signal at 1, the spool shifts proportionally to the applied pilot pressure to allow flow from port 2 to 3 bidirectionally. 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.
