Model Code for Counterbalance, Sequence and Pressure Reducing Valves
DGM *(*) -3- ** (*)
1 2 3
1 Type
R = Counterbalance function
R1 = Sequence function
X1 = Pressure reducing, underlapped
X2 = Pressure reducing, overlapped
X3 = Pressure reducing, overlapped,
low leakage
2 Function ports
For DGMR only:
TA = Counterbalance control function in
"T" port, controlled by pressure in
"A" port
For DGMR1 only:
PP = Sequence control in "P" port,
controlled by pressure in "P" port
For DGMX only:
PA = Pressure reducing function in line
P, piloted from A
PB = Pressure reducing function in line
P, piloted from B
PP = Pressure reducing function in line
P, piloted from P
3
Adjuster location
Option on DGMX only
L = Adjuster at "A"-port end of valve
Blank = Adjuster at "B"-port end of valve
4 Pressure adjustment range
For DGMX only:
Y = 1,40-7,0 bar (21-101 psi)
R = 1,40-45,0 bar (21-652 psi)
For DGMR and DGMX:
A = 3-30 bar (43.5-435 psi)
B = 3,5-70 bar (51-1000 psi)
C = 10-140 bar (145-2000 psi)
F = 20-250 bar (290-3625 psi)
