Forge are asking me do I want a piston or diaphragm actuator, and what spring do I want?
Which would be better for an actuator - piston or diaphragm?
If I'm running 25psi (1.75 BAR), what strength of spring should I use? (I'm thinking blue) Forge info below:
The 4 springs we offer are listed below under their relevant colour codes and related pressures. Running pressure is the lowest or minimum pressure the spring will operate at, which is important when considering which spring you choose. The spool up pressure relates to the vacuum pressure required to lift the spring from its static position, at which point the turbo waste-gate will start to open (spool up).
The actual rating for these springs is as follows, the
lower pressure being the spool up pressure and the higher pressure being the running pressure:
RED 17 psi (spool up) - 20 psi (running pressure) our product code FMAS049R.
BLUE 14 psi (spool up) - 18 psi (running pressure) our product code FMAS049B.
YELLOW 9 psi (spool up) - 15 psi (running pressure) our product code FMAS049Y.
GREEN 5 psi (spool up) - 10 psi (running pressure) our product code FMAS049G.
