Variants
The direct acting sequence valve feeds a secondary branch of a circuit when a
set pressure value is reached and suppresses the primary pressure.
It raises the safety level by making it impossible for the plant operators to set
a higher pressure rating, than that specified in the catalogue. It has a pack
spring with a mechanical stop (only standard screw and nut).
It has a galvanised steel body. The guided ball poppet is in tempered and
ground steel.
