Sequence Valve

402AA00033A - SEQUENCE VALVE 1PSC100P20S - DANFOSS
Description: 1PSC100P20S
Function: Sequence Valve, Pilot Operated, Poppet Type with Reverse Free Flow, Internal Pilot, External Drain
Sequence Valve, Pilot Operated, PoppetType with Reverse Free Flow, Internal Pilot, External Drain 350 bar [S000 psi]• 1S0 I/min [40 US gpm] 
This check. is a It pilot opens from operated, port 1 poppet to port type 2 when sequence the set valve pressure with a is reverse reached flow and free flows from port 2 to 1. It  can be directional used to valve, sequence where free operations flow is in a necessary system or in in the a service reverse line direction.

402AA00015A - SEQUENCE VALVE 1PS100P20S - DANFOSS
Description: 1PS100P20S 
Function: Sequence Valve, Pilot Operated, Spool Type, Internal Pilot, External Drain
Sequence Valve, Pilot Operated, Spool Type, Internal Pilot, External Drain 
3S0 bar [S000 psi]• 1S0 I/min [40 US gpm] 
This is a pilot operated, spool type sequence valve that opens from port 1 to port 2 when the setting is reached. This is ideal for sequencing a secondary operation while maintaining pressure in the primary operation, limiting pressure loss with constant or varying flows. 
407AA00028A - SEQUENCE 1UPS100P20S - DANFOSS
Description: 1UPS100P20S
Kick-Down Sequence Valve, Pilot Operated, Spool Type, Internal Pilot, External Drain 350 bar [S000 psi]• 1S0 I/min [40 US gpm] 
This is a pilot operated, spool type sequence valve that opens from port 1 to port 2 when the setting is reached. It then automatically vents the main spool, causing the inlet pressure in port 1 to fall to the pressure in port 2. Sometimes known as a'kick-down'valve, it can be used to sequence operations in a system limiting pressure loss, where the pressure in the second operation is much lower than the first.
