Application Notes PRESSURE REDUCING VALVES are pressure limiting devices that limit pressure in one portion of a circuit while leaving system pressure unaffected. They are available in direct-acting and pilot-operated types and as pressure reducing/relieving valves or as pressure reducing valves only. F102 010 DIRECT ACTING PRESSURE REDUCING / RELIEVING VALVES Direct-acting pressure reducing/relieving valves allow flow to pass from 2 to 1 until the pressure at 1 reaches the predetermined setting, at which point the spool shifts to restrict input flow from 2 (reducing mode) or to open flow from 1 to (relieving mode) as needed to maintain the regulated pressure at 1. Advantages of direct-acting pressure reducing valves are: Fast response Economical Direct acting pressure reducing valve 1 2 P10 020 A typical application for direct-acting pressure reducing valves is for pressure control in systems requiring two or more different pressure settings. These valves are best suited for low flow applications such as hydraulic brake or motor shift. Applications notes 5.2
Application Notes PILOT-OPERATED PRESSURE REDUCING / RELIEVING VALVES Pilot-operated pressure reducing/relieving valves operate similarly to direct-acting pressure reducing/relieving valves -- the spool allows flow to pass from 2 to 1 until the pressure at 1 reaches the predetermined setting and forces the pilot poppet off it s seat. This creates a pressure differential across the spool that causes the spool to shift and maintain regulated pressure at 1 in the same manner as the direct-acting pressure reducing/relieving valve. Advantages of pilot-operated relief valves are: Pilot-operated pressure reducing valve Smooth, stable response High pressure capability Precise pressure control with varying flow rates 1 2 P10 021 A typical application for pilot-operated pressure reducing valves is for pressure control in systems requiring two or more different pressure settings where high pressure capability and/or extremely precise pressure control is required.
