General Description and Operating Principle

DESCRIPTION:
Moog Hydrolux’s DPCMEE series differential proportional flow
control valves are used to regulate flow from ‘A’ port to ‘B’ port.
This valve uses a self-regulating hydraulic design for control of flow
rate by a current-controlled PWM signal.This screw-in cartridge
type valve is designed to fit in SAE style cavity with UN thread for
use in manifolds. It can also be used in conjunction with 2- or 3-
way pressure compensators as a 2- or 3- way pressure
compensated flow control valve.
OPERATING PRINCIPLE:
This valve is in a normally closed condition. In the closed condition
the pressure of the fluid at the ‘A’ port is sensed through the
orifice (2) and acts on the main spool (1). Since the pilot spool (4)
is a pressure balanced design, the main spool is held closed due to
the hydraulic pressure and the spring (3) force.When a current
signal is applied to the valve, the proportional solenoid (5) extends.
The force of the solenoid (5), which is directly proportional to the
applied signal, pushes the pilot spool (4) downwards.At this time
the pilot spool (4) connects the pilot side flow to the tank port
internally, thus creating a pressure drop across the orifice (2).This
will allow the main spool to move upwards, allowing flow from ‘A’
port to ‘B’ port.As the main spool (1) opens, the forces become
unbalanced between the spring (3) and solenoid (5) acting on the
pilot spool (4).At which time this force balance is reestablished,
the main spool (1) stops moving.This allows the valve to be used
for proportionally controlling the flow by steplessly varying the
input current signal.

Formula:
To calculate flow at different
pressure drops, use the
following formula:
Qx = Q∆p
10
Where:
Qx = Flow at pressure drop ∆px-lpm
Q∆p
10
= Flow at 10 bar pressure drop
(from the curves)
∆px = Pressure drop in bar at
which flow is calculated
