Real nice video on rebuilding a Johnson Controls pneumatic valve. Stromquist and Company has Johnson pneumatic valve repair parts in stock. Give us a call in our Florida or Georiga branches for your pneumatic valve repair parts.
Read any Honeywell catalog on control valves and most likely you will end up with red eyes and possibly a bald spot on top of your head from scratching it in frustration.
- Determine the throttling range for your control system. Let’s use 3-13#’s as an example.
- Next measure the ambient temperature at the thermostat with a precision temp meter.
- Adjust the setpoint knob on the T Stat to the current ambient temperature.
- Pull the branch line off the T-Stat and T tap a gauge between the T-stat and branch line.
- Adjust the calibration screw in the T-Stat until the branch PSI reads zero.
- Now adjust the calibration screw in the opposite direction until the branch pressure reads mid range. In this case our differential is 10#’s of pressure, so (13-3)= 10(diff) /2 or 3+5 = 8 psi.
- Verify the box damper and reheat valve(if applicable) are both closed. Fine tune if needed.
- Remove your calibration gauge and replace the branch line back onto the T-Stat.
- Adjust the T-Stat to the desired setpoint.
Your T-Stat is now calibrated…
Stromquist designed this great form to help you get the correct valve or valve/actuator assembly for your application. When you don’t have part numbers, it is important that we get as much information as possible when helping you choose the correct parts. You may not always have all of the information, but the more you can give us, the better. The back of the form even has diagrams to help determine if you need a two- or three-way, mixing or diverting valve. If you have any questions, need any help filling out the form, or would like to get a supply of these forms, call Stromquist at 1-800-241-9471.
For a while now the new buzz word for our clients and manufacturers has been “green” products, which are products that are specifically designed to cause less damage to the environment. In concept we can all agree that thinking green is a good idea.
Does a new green product make your client green? What can we do as distributors to help our clients become green?
When working with a facility manager who wants to become green, the first step is to identify what in the client’s system or processes is not working to peak efficiency. This seems like a no brainer, but it is amazing how many clients want to talk green when valves are leaking, pipes are not properly insulated, boilers are not firing efficiently, or oversized and undersized control valves and equipment are not addressed. As controls experts our integrity is on the line here folks! Take the time to look carefully at the job site and determine what core products you sell that will increase the bottom line energy savings to a client’s facility. Take the time to offer your help and knowledge even on the products you may not sell but may contribute in helping your product be more efficient.
When a client’s system is running properly it is easier for you to show the client where and how that new green product can help them become GREENER, and that my friend is the real color of green.
In the Georgia and Florida areas please contact your Stromquist and Company representative to help you with your energy savings needs.
We often get calls from customers who have a leaky valve and need help with finding a fix for it or a replacement. In some cases, you can purchase a repacking kit to repack the valve and take care of the leak. Sometimes you’ll need to replace the valve, and depending on the age of the valve/actuator assembly, you may have to replace the entire assembly.
To get started we need part numbers from the valve and the actuator. Based on this information we can determine if a repacking kit is available (and it usually is). It’s up to you if you want to try to repack it and see if that works or just buy a new valve. We can usually get a direct replacement valve or cross it to a new one if yours is old and obsolete. Depending on the age and the replacement options, you may also need a new actuator and linkage to work with the new valve.
So what if you can’t find any part numbers? It’s not that uncommon, especially on older models, and it takes a little more effort, but it’s still possible to find a solution. Here’s what we need from you: the type of valve (globe, ball, etc.), the size of the valve (1 in., 2 in., etc.), if it’s 2-way or 3-way, and if it’s mixing or diverting (if 3-way). It is also helpful to know the type of actuator on the valve and any information you can find regarding the actuator. Basically, the more details you can provide, the better we will be able to find what you need. If you need assistance in determining any of the above information, call Stromquist at 404-794-3440, and we can try to help you over the phone or send someone out (if you’re local) to look at what you have.
