PROPORTIONAL CONTROL VALVES, D681 TO D685 SERIES

The D680 Series Proportional Flow Control Valves are throttle

valves for 2-, 3-, 4- and 5-way applications.

These valves are suitable for electrohydraulic position, velocity,

pressure or force control systems, including those with high

dynamic response requirements.

With the new D633 Series directly driven pilot valve (DDV), a

further important step has been made in the direction of robust-

ness and energy saving. This linear force motor driven pilot valve

is developed as a variant of the proven Moog DDV Series.

The integrated electronics of the D680 series is also a new

development featuring SMD technology, and requires 24 V DC

power supply.

The valve series described in this catalog have successfully

passed EMC tests required by EC Directive. Please refer to the

respective references in the Electronics Section.

BENEFITS AND FUNCTIONALITY

DD

OPERATIONAL FEATURES OF THE DIRECT DRIVE PILOT VALVE

 A direct drive pilot valve requires no pilot leakage flow.

This results in considerable energy savings, especially for

systems with multiple valves.

 The dynamics of the direct drive valve is nearly indepen-

dent of the operating pressure.

 Reliable operation. The excellent pressure gain of the pilot

valve with spool / bushing, provides high spool driving forces

to the long stroke main spool. This ensures enhanced main

spool position control even with high flow forces and con-

taminated fluids.

 Excellent dynamics based on a high natural frequency allows

high main spool position loop gain, resulting in extremely

good static and dynamic response of the main valve.

DESCRIPTION OF THE DIRECT DRIVE PILOT VALVE

The D633 Series pilot valve consists of a permanent magnet

linear force motor, a drive rod connecting motor armature and

the spool guided in a bushing. The linear force motor contains

a coil, permanent magnets, pole pieces, an armature and a cen-

tering spring arrangement.

The 4-way spool controls fluid flow from the pressure port to

one of the load ports, and also from the other load port to

return. Deflection of the centering spring due to spool dis-

placement, provides a return force for the armature.

An electric current applied to the coil of the linear force motor

produces an electromagnetic flux depending on the current

polarity. This electromagnetic flux is superimposed on the per-

manent magnetic flux in the airgaps between armature and

pole pieces. This results in a polarity dependent displacement

of the armature against the centering spring force.

The spool being connected to the armature by a rod shares the

armature motion. Flow forces acting on the spool due to the

fluid flow through the valve, and friction forces between spool

and bushing due to contaminated fluid, are overcome by the

force motor. The position of the spool is approximately pro-

portional to the coil current.

OPERATIONAL FEATURES OF THE COMPLETE VALVE

 Valve body for high rated flow, optional with external pilot

supply using X and Y ports.

 Reduced spool drive area with D683 and D684 Series results

in the following advantages:

- improved dynamic response

- reduction in pilot fluid flow for fast movements of the

main spool.

 Failsafe versions available with defined safe spool position

using a spring and a 4/2-way solenoid valve for control flow

short circuit.

 The D680 series proportional control valves are of two-stage

design.

By combining a fast first stage, suitable main spool drive area

and integrated electronics, an optimum proportional valve

can be offered.

OPERATING PRINCIPLE OF THE COMPLETE VALVE

The position control loop for the main stage spool, position

transducer and pilot valve is closed by the integrated electro-

nics.

An electric command signal (flow rate set point) is applied to

the integrated position controller which drives the current in

the pilot valve coil.

The position transducer (LVDT) which is excited via an oscilla-

tor, measures the position of the main spool (actual value, posi-

tion voltage). This signal is then demodulated and fed back to

the controller where it is compared with the command signal.

The controller drives the pilot valve until the error between

command signal and feedback signal is zero.

Thus, the position of the main spool is proportional to the elec-

tric command signal.

VALVE FLOW CALCULATIONS

The actual valve flow is dependent on the spool position and

the pressure drop across the spool lands.

At 100% command signal (i.e. +10 VDC = 100% valve opening),

the valve flow at rated pressure drop ∆p

N

= 5 bar (75 psi) per

metering land is the rated flow Q

N

. For other than rated pres-

sure drop, the valve flow changes at constant command signal

according to the square root function for sharp edged orifices.

The actual valve flow Q calculated in this way, should result in

an average flow velocity in ports P, A, B or T of less than 30 m/s.

INSTALLATION DRAWING (inch)

The mounting manifold must conform to ISO 4401-07-06-0-94.

For maximum flow, the manifold ports P, T, A and B are

required to have 0.79 inch dia (deviation from standard).

Mounting surface needs to be flat within 0.0004 inch over a

distance of 3.94 inch. Average surface finish value, Ra, better

than 32 micro inch.

VALVES FOR APPLICATIONS WITH SAFETY REQUIREMENTS (FAILSAFE) WITH 11+PE CONNECTOR

For applications with proportional control valves where certain

safety regulations are applicable, a safe metering spool posi-

tion is needed in order to avoid potential damage.

Therefore, a failsafe version is offered as an option for the

multi-stage Moog Proportional Control Valves.

After switching off the 24 V supply to the safety solenoid valve,

this failsafe function causes a safe metering spool position, over-

lapped centered position or fully opened AT or BT.

In order to move the spool to the safe centered position with

D680 Series failsafe valves, the two control chambers of the

main stage are hydraulically short circuited via a 4/2-way sole-

noid valve. The spring force moves the spool into the overlapped

centered position.

In order to reach the fully opened position AT with D680 Series

failsafe valves , the spring force (after the control chambers

have been short circuited) pushes the spool to the end position

AT or BT.

With failsafe valves, it is possible to check whether the main

spool is in safe position. If the main spool is within the defined

safe range, the logic output signal at pin 11 is > + 8.5 V. If this

signal is < + 6.5 V, then the main spool is outside the safe range.

This logic signal may be delayed up to 500 ms. To reduce the

failsafe switching time, it is advised to both switch off the sup-

ply of the 4/2-way valve and the enable signal at the same time.

NOTE:

According to DIN-EN 954-1, a higher safety category can be

achieved if a failsafe valve is used.

FAILSAFE VALVE ELECTRONICS WITH SUPPLY VOLTAGE 24 VOLT AND 11+PE POLE CONNECTOR

Command signal 0 to ±10 mA floating

Valves with current command input

The spool stroke of the valve is proportional to I

= –I

5

.

100% valve opening P A and B T is achieved at I

4

= +10 mA.

At 0 mA command, the spool is in centered position.

The input pins 4 and 5 are inverting. Either pin 4 or 5 is used

according to the required operating direction. The other pin is

connected to signal ground at cabinet side.

Command signal 0 to ±10 V

Valves with voltage command input

The spool stroke of the valve is proportional to (U

4

– U

5

).

100% valve opening P A and B T is achieved at

(U

4

– U

5

) = +10 V.

At 0 V command, the spool is in centered position.

The input stage is a differential amplifier. If only one command

signal is available, pin 4 or 5 is connected to signal ground at

cabinet side according to the required operating direction.

Actual value 4 to 20 mA

The actual spool position value can be measured at pin 6 (see

diagram on the top). This signal can be used for monitoring and

fault detection purposes.

The spool stroke range corresponds to 4 to 20 mA.

The centered position is at 12 mA. 20 mA corresponds to

100% valve opening P A and B T .

 Minimum cross-section of all leads ≥ 0.75 mm

2

(AWG 18).

Consider voltage losses between cabinet and valve.

 Note: When making electric connections to the valve (shield,

protective earth) appropriate measures must be taken to en-

sure that locally different earth potentials do not result in ex-

cessive ground currents.

Also see Moog Technical Note TN353.

 Supply 24 V DC, min. 18 VDC, max. 32 VDC

Current consumption max. 800 mA

Additional supply 24 V DC failsafe valve and current consump-

tion 1.35 A to pin 9 10.

 All signal lines, also those of external transducers, shielded.

 Shielding connected radially to ⊥ (0 V), power supply side,

and connected to the mating connector housing (EMV).
