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.
