The essence of control

High-quality servovalve performance is essential to controlling the forces and motionsof mechanical testing. Servovalves are critical to reliable test system performance andare the final control element in most MTS closed-loop systems. As an industry leader
in servohydraulic testing, MTS has a deep understanding of the unique and demanding
requirements of servovalve operation. The success of our servovalve portfolio extends
for decades, spanning an incredible variety of markets and applications.
Today, we continue to apply this experience and expertise as we provide durable,
reliable servovalves for a wide range of flow rates and performance curves. With ourcomplete line of servovalves, we can configure combinations that generate the ideal
blend of power, finesse and overall performance.

High Durability

Extreme Repeatability

MTS servovalves feature rugged designs
for long operating life in dynamic
applications. Fault-tolerance helps extend
operation in the event of errors andpreserve the integrity of test data. Also,a high degree of contaminant tolerance
gives test teams ample time to diagnose
and resolve operating issues before they
compromise test results.

Repeatable, reproducible results are
critical to test integrity and validity.
Because MTS servovalves are designed
and manufactured according to stringent
specifications, you can expect them tomeet or exceed expectations from lab
to lab, system to system, and test to test,
whether operators are experienced experts
or relative newcomers.

Superior Fidelity

Elegantly engineered MTS servovalves
allow test professionals to move amillion-pound force capacity actuator a
few microns or complete fatigue tests
that run for billions of cycles – all withexceptional accuracy. Tight tolerances
ensure MTS servovalves achieve finesse
and produce precise moments, especiallyat the high end of performance curves.

Series 252 Servovalves

MTS Series 252 Servovalves are two-stage, four-way servovalves specifically designed
for low to medium flow rates of 3.8 to 227 lpm (1 to 60 gpm*) in high-response
servohydraulic systems. Depend on these workhorse components for solid,
consistent performance.

Performance

Each Series 252 Servovalve includes atorque motor and two stages of hydraulicpower regulation. The torque motor
controls the first stage by positioning a
flapper that controls hydraulic fluid
flow from two nozzles in the first stage.
Differential pressure positions the second
stage spool, which controls the direction
and rate of hydraulic fluid flow to theactuator.
These servovalves incorporate all theadvantages of closed-loop control. As
the second stage spool reacts, a feedback
spring by the spool counters the actionof the torque motor and flapper. By thetime the spool reaches the commanded
position, the motor and flapper arecounteracted. Flow from both nozzles isequal and the spool stops. This design
ensures precise control of spool position,a high hydraulic driving force on thespool and a high error-force gradient.

ReturnSeries 256 Servovalves use a Series 252
Servovalve to drive a larger spool in athird stage. An internal linear variable
differential transformer (LVDT) monitors
the third-stage spool position and provides
a signal to the servovalve controller ona three-stage valve driver. The valve
controller compares the spool position
with the DC error signal and alters thecontrol signal to the torque motor in thefirst stage accordingly. When DC error
reaches zero, servo action in the inner
loop decreases and both spools return totheir null positions, stopping the flow tothe actuator.
Common Applications

6

Typical applications for Series 256
Servovalves include position, load, or
velocity control of larger hydraulicactuators in highly dynamic applications,as well as pressure control in a dynamic
pressurization system. Some models canbe configured with different sizes of pilot
stage servovalves for unique performancerequirements. Be sure not to exceed
performance requirements significantly,
because systems can be difficult tocontrol if servovalves are oversized fora specific application.

MTS Series 257 Servovalves are two-stage, four-way servovalves featuring anelectrodynamic pilot stage for maximum performance. These valves accommodate
very high-flow closed-loop servohydraulic testing applications that require extremely
high precision.

Common Applications

Series 257 Servovalves are typically usedin high-frequency systems. Specificallyengineered to handle very high flow rates
with equally high precision, these valves
tend to require a greater degree of care
and attention. It is important to warm up

these valves before testing begins to
avoid the risk of galling, and to checkvoice coil resistance every six months.
Special compensation networks in thevalve controller (available from MTS)
help maximize dynamic performance.

Performance

Series 257 Servovalves consist of ahigh-response, voice coil-operated pilot
stage (single-stage servovalve) that controls
a high-flow, four-way main stage. Verystiff springs suspend the pilot, enabling ahigh first natural resonant frequency.
During operation, the valve controller
compares the DC error to the main stage
spool position indicated by the LVDT, inorder to determine the magnitude andpolarity of the valve command signal.
This signal is sent to the power driver,which boosts it and adds damping factors
to create the servovalve control signal.
Then it is applied to the pilot stage voicecoil to induce a magnetic field that interacts
with the magnetic field of a DC-excited
field coil. The difference in polarity
causes the pilot spool to apply fluid tothe main stage spool, which ports fluid
to the actuator.
The main stage LVDT generates theservovalve feedback signal. Pilot spool
movement causes the magnetic core in
the linear velocity transducer to move,creating the pilot velocity feedback signalthat combines with the valve commandsignal to allow higher inner-loop gain
settings that expand system capabilities.

Maintenance, Care and Service

As one of the most experienced providers of servovalves, MTS can put together aconfiguration that meets virtually any application need. We offer a wide selection ofstandard products as well as more customized configurations – all of which can be
carefully adapted and optimized as your application needs evolve. In addition, MTS
offers a complete line of related services to ensure your servovalves deliver outstanding
performance over a long life span.

Service Intervals

Fluid Cleanliness Standards

If hydraulic fluid is in good condition
and kept clean, MTS servovalves should
last a very long time without needing
service. The importance of clean fluid
cannot be overstated; dirty or silt-laden
fluid is the major cause of servovalve
problems. Typically, when valves must be
serviced sooner than expected, the most
likely problems are clogged filters andvarnished valve spools, both of which
are caused by dirty fluid. In general, fluid
cleanliness should meet ISO 16/13/9
standards. The table shows recommended
control limits.

Characteristic

Lifecycle Extension

To prevent common servovalve problems,
MTS recommends maintaining fidelity
through precision hydraulics management.
This involves having servovalve performancetested after 7,500 hours of use (assuming
fluid meets recommendations). It isalso essential to monitor hard particle
contaminants that lead to third-bodyabrasion and rapid deterioration in
performance.

Common Problems and Solutions» Whistling. This sound may occur
when system pressure is on, theactuator is not moving and the system
is under control. The high-pitchednoise coming from the servovalve iscaused by high-speed leakage flow
through metering edges, which areintentionally made to zero lap. To
eliminate the noise, simply increase
the return line pressure.
» Squeaking. If squeaks are synchronizedwith actuator movement, it is likelythat the spool is moving across thenull position and fluid flow in the
return line is unable to stop due to
fluid inertia. To eliminate the noise,increase the return line pressure.
» Irregular movement. Irregular actuatoror servovalve movement can be causedby dirty hydraulic fluid. Contaminants
temporarily clog the gap between the
servovalve’s flapper and nozzles,
causing the servovalve and actuator
to jerk. Poor system design may also
be the cause. For example, hysteresis

and threshold will result if a small
actuator is used with a high-flow
servovalve, or if the pilot stage is too
big for the output stage. In general,lowering pilot supply pressure, adding
a small amount of dither, and retuning
the system may help improve system
disturbance rejection.
» Squealing. Occasionally, when alow-flow three-stage servovalve isused to control a large, long-stroke
actuator, the valve will squeal whenthe main stage supply pressure is on;an oscilloscope shows spool oscillation,
but tuning does not stop the noise.
One possible source is mechanical orhydromechanical resonance. Rotatinga Series 252 Servovalve 90° or 180° may
cut off the mechanical feedback path.
For a Series 256 Servovalve, decreasing
the size of the pilot servovalve may
help with squealing. Otherwise, you
can eliminate squealing by adding apiece of hose to C1 or C2 port of pilot
stage (-4 or -6 size, 1 to 2 feet long).

Fluid Care

Series 252 Specifications

Choose the MTS Fluid Care Program toprotect your investment, mitigate riskof downtime, improve servovalve
performance and help reduce total costof ownership. This program combines
precise fluid assessment with expert field
service engineering to identify and resolve
fluid contamination issues before they
compromise your lab’s productivity.

Maximum operating pressure

We work with you to design a sampling
schedule that aligns with your usage andperformance goals. An MTS field service
engineer (FSE) then takes samples, reviews
report results with you, and helps you
determine if and when a maintenanceintervention is required. Your FSE may
also discuss results that are out of normal
range, monitor trends and provide anannual summary of results, including
fluid condition trend information andrecommendations for future actions.
