While I was in the Orlando office the other day Pat Marley took a call from a client asking how to mount his Belimo TF series actuator to his Belimo ball valve using the WTF mounting adaptor kit. Sadly the Belimo WTF mounting adaptor kit comes with no instructions on how to undertake this proceedure. Pat, being Pat using the speaker phone walked the client through the mounting proceedures and was kind enough to walk through the installation again for my camera also so we could present this article to you… our clients.

The idea for this article came across my computer in the form of an e-mail sent to me by a fellow employee of Stromquist and Company with an attached photograph.
I know we all strive in our chosen industry to do things right with as much professionalism as our clients will afford us. I also realize at times even the best of service personnel will make installation mistakes. Some of these mistakes are quite humorous, some are quite expensive to fix, and some of these installations could be quite possibly dangerous.
Since the Control Trends website is duty bound to get, you our readers, the best information on new controls, controls installation, and new trends in the control industry would it not be appropriate to also show how not to install a product?
We at Control Trends will not mention anyone’s name or any company name we do this only as an insight to possible installation mistakes and how to avoid these mistakes.
This first installation is quite humorous to me and I call it “The Sunshine State Weather Protector” Read More
This article is taken from a flyer written by Belimo about four years ago called “The Belimo Code” We thought we would revive the article to help our clients remember or for the newbie’s to learn from. This article will cover most of the Belimo actuators you will see in the field, for the others, give us a call and we will “Break the Code” for you.
The first part of the Belimo code is why Belimo? Belimo is a Swiss company so the name Belimo is derived from its Swiss meaning…
BEraten Consulting
LIfern Delivering
MOntieren Mounting
Now that we have the Belimo name code “cracked” lets breakdown the actuator codes…The first letter of the actuator code is all about TORQUE…
G 360 in-lb G= GIANT
A 180 in-lb A=AWESOME
A 133 in-lb A=AWESOME
N 90 in-lb N=NORMAL
L 35-45 in-lb L=LITTLE
T 18 in-lb T=TINY
The second letter of the actuator code is about MOTOR ACTION…
F=SPRING RETURN (on power failure the motor will return to its normal position)
M=NON-SPRING RETURN (on power failure motor will stay in its current position)
The third letter is about motor speed…note: non-spring return actuators can combine a forth letter to designate MOTOR SPEEDS…
Q=Quickest running (non-spring return)
C=Fast running
A=No Position Feedback (spring return only)
No Letter= Normal Speed
B=Basic
X=Customized
Next will be a set of numbers…These numbers are about POWER SUPPLY…
24=24 VAC/DC
120= 120 VAC
230= 230VAC
After the POWER SUPPLY numbers (stick with me) are the CONTROL letters/numbers…
Blank=On/Off (spring return)
-1= on/off (non-spring return)
-3= Floating Point (spring return)
-3= On/Off, Floating Point (non-spring return)
-3-P5= On/Off, Floating Point with 5Kohm Feedback (non-spring return)
-3-P10= On/Off, Floating Point with 10Kohm Feedback (non-spring return)
-SR= 2-10 VDC
-PC= 0-20 volt (Phasecut)
-MFT= Multi-Function Technology (program what you want)
-MFT95= 0-135ohm
-MFT-20= 6-9 VDC 20 VDC power supply (spring return)
At last we have our last letter which will deal with actuator OPTIONS…
-S=Built in auxiliary switch
-T= Terminal Block
Blank=Cable Version
We have now broken ‘THE BELIMO CODE” until Belimo introduces more actuators, then we may need to add to our code breaking article. If you need Belimo actuators give us a call at Stromquist and Company @ 1-800-241-9471(Atlanta) or at 1-800-638-7828 (Florida)and we will be “Code Breakers” together.
In just about every application where the flow of air, water, oil, gas, or any other fluid needs to be stopped or started a solenoid valve is incorporated into the piping system.
Here is a list of common questions that need to be addressed to properly start the selection of your solenoid valve needs.
Valve Type 2-way, 3-way, 4-way
Operation Normally Open, Normally Closed, Universal
Pipe Size Pipe size or flow requirements
Media Fluid to be controlled (what’s going through valve)
Pressure Minimum and Maximum operating pressure
Temperature Minimum and Maximum fluid and ambient temperature
Voltage Voltage and frequency to be used
Extras Special seals, special seats, manual reset, explosion proof, etc.
Since most of the day by day uses of solenoid valves are 2-way/ 2-position let’s look at the above questions closer.
Operation This the most misunderstood question. Normally Open simply put means that when the valve is not energized (no power to coil) the valve is open allowing the media to pass through the valve. When the Normally Open valve is energized (power to coil) the Normally Open valve will shut down not allowing media to pass through the valve. The Normally Closed valve is of course opposite to the Normally Open valve. When the Normally Closed valve is not energized the valve will not allow media to flow through the valve. When the Normally Closed valve is energized the valve will open to allow media to flow.
Pipe Size Most all valves are listed by pipe size and Cv rating along with the valve’s orifice size. Notice that the smaller the orifice size is on a solenoid valve that the Cv rating is reduced. So what Cv do you need? Here is a “rule of thumb”. Cv = 50% of the gpm flow through a valve based on a 2-5 psi pressure drop between the inlet and outlet of the valve. So by way of example if you need 10 gpm of water to supply your need to some equipment with a 2-5 psi pressure drop the solenoid’s Cv factor would be 5.
Media Most common of media type for solenoid valves is air, water, gas, steam, or oil.
Pressure Maximum Operating Pressure Differential (M.O.P.D.) The maximum operating pressure differential refers to the maximum difference in pressure between the inlet and the outlet, against which the solenoid can safely operate the valve. If the pressure at the valve OUTLET is not known, it is safest to regard SUPPLY pressure as the M.O.P.D. Minimum Operating Pressure Differential is that which is required to OPEN the valve and keep it open. 2-way way solenoids with a floating piston or diaphragm, the valve will start to close below the minimum operating differential pressure.
Temperature The normal limitation of 32 degrees F (O degrees C) is advisable for any valve that might contain moisture (water Vapor). Where freezing water is not a factor, minimum ambience as low as 0 degrees F (-18 degrees C) can be tolerated. Special constructions are available for lower temperature ratings. Maximum ambient temperature is usually controlled by the UL listing for the coil insulation available for the valve.
Voltage There are various coil voltages available for solenoids to meet your needs. Please remember when asking for valves to state if the voltage is AC or DC and whether 50 or 60 cycles.

One of the really cool things about direct coupled actuators like those made by companies like Belimo, Honeywell, Johnson, Siemens, and Invensys TAC is that they can be usually be inter changed. Meaning if you have a 35 inch pound Belimo direct mount actuator, but there is not a Belimo 35 inch-pound direct mount actuator to be found in your city, you should be able to replace it with a Honeywell 35 inch pound direct mount actuator, or a Johnson 35 inch-pound direct mount actuator. Although each brand of actuator has it’s pros and cons they all for the most part close in quality and value. So if you have a job that has all Belimo and you need a replacement Belimo actuator but your local distributor does not have one on the shelf and you cannot wait for a Belimo actuator to be shipped then most likely you can find a Read More

BELIMO USA provides great products and as a Platinum Belimo stocking distributor STROMQUIST & COMPANY loves the solutions Belimo products allow us to bring to our customers. Our customers love the great Belimo damper and Belimo valve actuators, and cool money saving products like the Belimo piping packages. One of the really innovative Belimo products that can save major installation dollars and provide on going energy savings long after the installation is the Belimo PICCV ( Pressure Independent Characterized Control Valve).
Now that might sound like a mouth full, but what the Belimo PICCV valve is a Belimo differential pressure regulator in series with a Belimo characterized control valve. The regulator in the Belimo PICCV valve controls the amount of flow that passes through the Belimo control valve by the diaphragm that moves according to changes in pressure over the Belimo control valve. Thus the flow remains constant no matter what happens with pressure changes.The pressure regulator absorbs all pressure changes so the differential pressure is held constant over the Belimo control valve thus delivering consistent predicable flow.
