DESCRIPTION A high pressure, screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation. OPERATION When in neutral, the HPD42-S50 allows flow from 3 to 2 bidirectionally while flow is blocked at 4. On remote pilot signal at 1, the valve's spool shifts to allow flow between 3 and 4 while blocking at 2. The spring chamber is vented to the tank through port 5.The vented spring chamber allows the valve to be fully pressurized at 1, 2, 3, and 4 without affecting required pilot pressure at 5. Pressure at port 5 will increase the required pilot pressure at a 1:1 ratio. FEATURES • Hardened spool and cage for long life. • 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%. 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. Flow: up to 265 lpm (70 gpm) with seal option N, V and U. 246 lpm (65 gpm) with seal options NS, VS and US. Fatigue Rating: 2 million cycles at 420 bar Proof Pressure: 690 bar (10000 psi) Burst Pressure: 1380 bar (20000 psi) Maximum Internal Leakage at 350 bar (5075 psi) at 32 cSt. HPD42-S50: Ports 3-4: 328 ml/min.
