SystemStak™ Pilot Operated Check Valves

DGMPC
General Description

These valves are single or dual check units. Dual check units

have identical check elements located in the “A” and “B”

cylinder port lines. The check valve poppets are moved into

the open position by a central pilot control spool which moves

toward one check or the other, depending on which port is

pressurized.
The check valve located in the return circuit is opened by the

operating pressure in the primary circuit. When the pressure

in the pilot line is vented, the check valve will remain closed.
The pilot spool area to valve seat ratio is 3:1 on standard

models, and 20:1 on models with the decompression feature.
Check valve cracking (opening) pressures of 1 bar (15 psi),

2,5 bar (36 psi) and 5 bar (73 psi) are available. Please note

that back pressure on the downstream or free-flow side of

the pilot check valve may prevent the valve from opening

in certain situations. (Back pressure opposes pilot pressure

trying to open the valve.) In such cases, pilot pressure

required to open the decompression poppet and valve can be

calculated as follows:

To open valve or poppet in line A:

To open valve or poppet in line B:

Where:
P

= Pressure at A

= Cracking pressure

= Pressure at A1

= Pressure at B

= Pressure at B1

In the above cases, substitute cracking pressure and area

ratio from the following:
Cracking pressure: 1, 2.5 or 5 bar according to model code

position 6 (and position 10 for second function).
Area ratio factors:
Standard valve: 3
Decompression poppet: 20
