1 SEQUENCE SE08A DIMENSIONS (mm) HYDRAULIC DIAGRAM ASSEMBLY DIAGRAM DESCRIPTION Sequence valves, direct acting, external pilot. Poppet type. CROSS SECTION OPERATION Oil flow is permitted from 2 to 3 when the pressure value in 2 is same as the spring set value. The passing between 2 and 3 is shut upon reaching a set percentage value of the setting pressure (valve differential control). These valves are mainly designed as pilot valves to control charging of accumulators. When the accumulator is charged the flow from 1 to 2 must be to tank. PERFORMANCE Maximum flow: 5 l/min. Maximum Pressure: 210 bar Application range with standard springs: 5 50 bar (test setting: 30 bar at 1 l/min.) bar (test setting: 50 bar at 1 l/min.) bar (test setting: 100 bar at 1 l/min.) bar (test setting: 180 bar at 1 l/min.) Working pressure restore value: 15% of the valve setting value. Oil leak from 2 to 3: 0.10 cc/min. (2 drops) at 210 bar and oil viscosity of 46 Cst. Working temperature: Minimum -25 C max 90 C with standard BUNAN gaskets Minimum -20 C max200 C with optional VITON gaskets RECOMMENDATIONS Fluid: best use mineral oil with viscosity ranging between 10 and 200 Cst.
