Does Your Valve Cause You
More Problems In The Down Direction?

Do You Have A Noisier
Valve?
If you have answered Yes
to one of the questions then you need to read the following... Our
Experience with Elevator Control Valves has always caused us to seek
European valve suppliers for better Reliability. Over
the past two years, EECO has made major strides and improvements to
their value, making them perhaps the most reliable on the market. With
this said we believe that EECO should now merit your strongest
Consideration. Please read the
following write up.
WHAT
MAKES EECO SUPERIOR!!
Simplicity – The
design of EECO hydraulic control valves are based on simplicity and
serviceability with reduced field labor in mind. Unlike those that are
layered with “design work around” and a multitude of parts creating
difficulty and hardship for field labor to service and adjust, therefore,
often requiring complete valve removal and return for factory service;
resulting in equipment down time, lost revenue and poor customer relations.
With simplicity EECO valves are quickly field serviced, eliminating
downtime, poor customer relations and lost revenue.
- Ease
of adjustment
- Field
serviceable means it is not necessary to return an EECO valve for repair
- EECO
Valve requires less inventory and saves money
Valve Sizing – Some
other valves handle an oil flow rate range from 20 to 185 GPM with sizes to
handle their flow rates. If the flow rate is greater than 185 GPM a more
expensive larger valve is required. Once again EECO leads the way in
technology, resulting in cost benefits to our customers, since EECO
comparable size valves convert a much wider flow range (up to 220 GPM and as
little as 5 GPM with special sizing).
It is important to use the proper size
valve for the specific application in order to achieve optimum performance.
Another technical advantage when using an EECO valve is the simplicity, in
which a valve may be resized in the field, should there be an incorrect
selection or change in job sire conditions. This feature is unique to EECO
only.
- A
broader range of flow rates mean economic savings
- Resizing
can be done quickly in the field
Installation and Adjustment – Every
EECO valve is tested at three separate stages to assure its integrity and
performance quality. The final stage is testing and adjusting to an actual
elevator. Consequently, only “fine-tuning” may be required in the field,
a distinct EECO labor saving advantage. The performance graph of each valve
is archived at EECO for future reference and may be shipped with the valve
upon request.
EECO’s simplistic design brought ease
and reliability of adjustment to the field. EECO valves have 10 adjustments.
The 5 up adjustments are independent form the 5 down adjustment. When up or
down adjustment is made in sequence the valve is set and will hold
adjustment over a wide range of temperature, load and with age. Other valves
have built in numerous “check balls” to try to facilitate independent
adjustments. However, leaks through these check balls create frequent
adjusting and performance problems.
An EECO valve can be left or right hand,
with threaded or grooved ports for quick installation. A low oil switch and
a pressure gauge can be installed prior to shipment, if specified.
- 3
Stages of testing with the final stage to an actual elevator system
- Each
valve is adjusted to specific jobsite conditions, requiring only minor
‘fine tuning” in the field
- Each
valve’s performance is documented and archived
Noise Level – Controlled
environment resting proves EECO valves are quieter. Higher noise in other
valves is the result of a larger number of turns in the flow path, which is
most noticeable in the up direction. Additionally, the EECO valve
incorporates an isolation washer (bumper) in the bypass area; this dampens
the transmission of noise and vibration to the valve body and ultimately to
the car platform.
- Test
proves EECO valves are quieter
- Specific
designs incorporated to limit noise
Seals - All EECO valves use high
temperature Viton seals to assure continued performance through a broad
range of oil temperature. EECO valves reliability operate for several
million cycles without problem or need of service, provided the oil is kept
clean and the oil temperature does not exceed 150º F for prolonged periods
of time.
There are no O- rings or seals between
the EECO valve body and its flanges. Therefore, it is very easy to open the
valve and access all the internal parts without risk. This clean design is
unique to EECO, whereas others are fraught with many seals and ”retaining
plates” that make field serviceability, labor intensive and next too
impossible.
- EECO
uses only high temperature Viton seals suitable for hot running jobs
- No
O rings between the valve body and flanges, therefore easier to service
- Millions
of trouble free operating cycles
Operational Stability and Consistency
of Ride Quality - EECO
temperature compensated valves consistency provides stable operation over a
wide range of temperature, pressure and with age. They particularly suitable
for high temperature conditions, maintaining floor-to-floor travel time and
accuracy. This results in less motor run time and subsequent heat
dissipation in the oil. Frequently EECO valves are selected for those high
temperature conditions where others fail.
- EECO’s
unique designs compensates for variation in oil temperature
- Consistent
floor to floor travel time
UNPARALLELLED TECHNICAL SUPPORT AND
CUSTOMER SERVICE
The EECO customer service department is
known by industry field personnel for providing the best possible product
support and service. This fine reputation has caused field personnel to seek
technical help for value products other than EECO’s. As company policy,
the EECO customer service department, follows up with each call to find the
nature of the problem, resolve it and finally help our customer in possible
prevention of repeat problem. The volume of service calls seeking help oh
non EECO value products clearly indicates a decided choice by the end user
to seek help from that other that OEM.
In addition to out website (www.eecovalves.com)
technical information and help is just a toll free phone call always from
7:30 AM until 4:30 PM time. EECO has developed and provides free of charge,
training tools on installation, adjustment, troubleshooting and servicing
valves. EECO has developed a training video in VHS or CD format that covers
all aspects of valve training, again free of charge. In addition to valve
training simulators and valve cut away models, EECO also provides training
classes, either at one of our two factory facilities or at a customer’s
facility.
- EECO
is sought by industry field personnel for technical help on non EECO
products
- EECO
company policy is to follow up on all service calls
- A
variety of training tools are available free of charge
- Hands

Summary
EECO
valves have been used around the world fro more than 50 years and are
controlling tens of thousands of elevators. EECO valves are well known for
their case of handling and serviceability in the field. The ride quality and
performance provided by a property sized and adjusted, EECO valve is
superior bar none. EECO provides a two-year warranty on all valves and
provides 100% continued support. Customers are encouraged to contact EECO at
any time for any problem they may encounter in their hydraulic elevator
systems. EECO has proudly served the elevator industry for 58 years and
continues to do so in the 21st century.
