Size E:
Examples of how to use the characteristics for pressure control spools
Example 1: Determining the oil flow Example 2: Determining the spool size
Given:
•
Spool type B
•
Pressure setting P
P
: 160 bar [2320 psi]
•
Load pressure, LS
A/B
: 100 bar [1450 psi]
Result:
Oil flow = 75 l/min [19.8 US gal/min]
Given:
•
Max. oil flow, Q
A/B
: 90 l/min [23.8 US gal/min]
•
Pressure setting P
P
: 150 bar [2175 psi]
•
Load pressure, P
LSA
: 125 bar [1810 psi]
Result: D spool
(see Pressure CS flow characteristics, size D)
Normally a smaller spool can be chosen with pressure control. It is our experience that the spool can be
one size smaller than with normal flow control.
