HydraForce, Inc. Piloted, 4-Way, Spool Valve, Vented Spring Directional Valves HyPerformance® HPD42-S62

A high pressure, screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic directional valve. OPERATION In neutral position, the HPD42-S62 allows flow between ports 2 and 3 and between ports 4 and 5. On remote pilot signal at 1, the valve shifts to block flow at all ports. The spring chamber is vented to the tank through port 6. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, 4 and 5 without affecting required pilot pressure. Pressure at 6 will affect required pilot pressure at a 1:1 ratio. FEATURES • Hardened spool and cage for long life. • Optional sealed spool between ports 1 and 2. • All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%. RATINGS Operating Pressure: 350 bar (5075 psi); 10% cycle life: 420 bar (6090 psi) Note: All HyPerformance™ products are tested for 900K cycles at 350 bar and 100K at 420 bar Proof Pressure: 690 bar (10000 psi) Burst Pressure: 1380 bar (20000 psi) Flow: up to 189 lpm (50 gpm) with seal options N, V and U with no flow restriction; up to 189 lpm (50 gpm) with seal options NS, VS and US with flow restriction from ports 2 to 3 of 132 lpm (35 gpm) maximum.
