My primary concern is the potential of a mini-revolt if we switch from high solid walls to mid-height walls (53") with 10" of glass.
I'm looking for feedback from anyone who works in this type of cube.
My company is going to renovate the engineering office (12 people) with new cubicles.
Currently, we have solid 61" high cubicles from the 1970s (at least, that's what they look like)
Engineers tend to recluse themselves in their hide-aways, which doesn't help with communication and...
The one "problem" with direct acting valves is the 5 f/s velocity limit for PVC solenoid valves.
I've run across it with two manufacturers. Plastomatic and Hayward.
I haven't been able to determine if that is a characteristic of direct acting valves in general or just those specific...
Thanks guys.
I've just read both attachments.
For the sake of this discussion, a pilot operated valve (POV) would be the floating diaphragm valve design.
According to the lit, it sounds like the POV starts to close if the flow through the valve is low enough to result in < 5 psi diff.
I think a...
Many (most? all?) pilot operated solenoid valves require a 5 psi pressure differential to open.
An example of the type of solenoid valve I am referring to is here ...
Problem: A part is dimensionally/physically identical in all variations. The only difference is the voltage and material the part is made from.
Every combination of voltage and material means there can be dozens of variations.
Each variation has a unique part number that needs to show up in a...
Pilot operated valves are approx 1/2 the price of direct acting valves.
I need to make sure I fully understand the limitations of pilot operated valves before I advise our engineering group to avoid them.
One "problem" the direct acting valves seem to have in common is they are more sensitive to...
I am unclear why a valve would have inlet/outlet sizes that requires a reducer fitting at each end of the valve, thus increasing the overall length.
In my applications, space is often at a premium.
With the 1/2 ASCO valve in the OP example, I would need to flow 10 GPM to maintain a 5 psi...
Thank you all, for the replies.
I've been waiting for ASCO to explain why their valve needs a 5 psi minimum pressure differential, per their literature. ... still waiting.
To answer some questions ...
A number of sources say that 5 ft/sec should be the max velocity through PVC pipe.
It's...
Question 1: Do I need a restriction in each branch of our plumbing?
According to a variety of sources, we should be limiting the velocity through our PVC pipes to 5 ft/sec.
5 ft/sec can be translated to GPM for each pipe size.
If I need to flow 3 GPM thru the branch to Tank A, I can pick...
I'm trying to find any standards concerning the design of free-standing steel structures like the attached image.
This structure supports the rails for an overhead automated hoist. Capacity, 2000 lbs.
I am concerned that our current analysis of the structure design does not sufficiently look at...
