Pressurisation times as to the number of turns of the regulation
screw, with downstream volume of 5 litres. A = 5 turns - B =
4 turns - C = 3 turns - D = 2 turns - E = 1 turn. K = number of
turns of the regulation screw required to obtain the required
pressurisation time with an inlet pressure of 6 bar. Variations of
the inlet pressure can cause deviations of the pressure time by
± 20%. K = t/V where: V = volume of the downstream system in
litres; t = desired pressuring time in seconds.
EXAMPLE:
V = 5 litres
t = 16 seconds
K = 16/5 = 3,2
Using in the graph this value K, the number of turns of the
regulation screw will be approx. 0,8.
