sequence valve

An automatic sequencing valve evenly doses each sector in turn.

The retractable gear is hydraulically operated from a T-33 sequencing valve with electric powered gear doors.

Sequence valves control the sequence of hydraulic circuits; to ensure that one hydraulic cylinder is fully extended before another starts its stroke, for example.

The hydraulic lines had been broken by the incorrect retraction sequence of the port bogie, itself caused by incorrect setup of a replaced sequence valve.

Designed and supervised a Low Pressure Effluent Dosing (LPED) system incorporating automatic sequencing valve to alternately dose 1200 metres of LPED trenches in the disposal area.

A large single chamber septic tank with an Orenco (USA) high turbine pump services a LPED disposal area via an automatic sequencing valve which evenly doses each sector of the disposal area in turn.
