Quick Reference Cartridge Valves Technical Information Sequence Valves Application Notes SEQUENCE VALVES Application notes Sequence valves As the name implies, sequence valves control a sequence of operations. Sequence valves usually use a pressure signal to shift a spool, thereby opening or closing a flow path at a pre-set pressure. Sequence valves Direct-acting sequence valves are spooltype valves with a spring force holding the spool closed. When inlet pressure exceeds the spring setting, the spool shifts to direct flow to a second function. Internal-pilot with external drain...

Quick Reference Cartridge Valves Technical Information Sequence Valves Application Notes Kick-down sequence valve 1 A common application for a kickdown sequence valve is as a safety device in circuits where overloading or overheating could cause damage if pressure is held for an extended period of time. UNLOADING VALVES Another type of sequence valve is commonly known as an unloading valve. The unloading valve blocks flow at 2 until sufficient pressure exists at 1 to pilot the poppet open against the pre-determined spring setting and allow flow from 2 to 3. If the pressure at 1 drops below...

Quick Reference Cartridge Valves Technical Information Sequence Valves Application Notes APPLICATIONS Unloading valves Common applications for unloading valves include: Application notes Sequence valves Pump unloading in an accumulator charging system Accumulator charging/unloading valve For higher flow rates the unloading valve may be used to pilot a larger logic element Accumulator charging/unloading pilot valve Pump unloading in a 2 pump highlow circuit High-low pump unloading TO SYSTEM HIGH FLOW MAIN PUMP HIGH PRESSURE HOLDING PUMP P103 224

Quick Reference Sequence valves Both direct-acting and pilot-operated sequence valves have many common applications including: • Providing a sequenced series of operations such as in a clamp and lift circuit Clamp & lift circuit LIFT C YL. Use as a relief valve where the return line has high or varying backpressure. The independent spring chamber drain line provides a relief setting unaffected by downstream pressure.
