CONTENTSSECTION 4 - SEQUENCE VALVESSequence valves are similar to relief valves but with their spring chamber referenced to a separatedrain port. Direct acting and pilot operated versions with and without free flow checks are available inthis section, with flows up to 200 litres/min (52 US GPM) and pressures up to 350 bar (5000 psi).4SELECTIONSECTION SERIES APPLICATION RANGE PAGE1DSDirect acting guidedpistonLow pressure applications and lowflow systems where pilot leakagemust be kept to a minimum140 bar(2000 psi)150 litres/min(40 US GPM)4-111to4-1211PSPilot operatedsliding spoolSuitable for most sequencingapplicatiions with low pressure dropover widely varying flow rates.
