Control Valve Actuators Failure Modes Custom Search Control valves can be built from various combinations of valve actuator and valve body. The combination of actuator and valve body is usually chosen to provide a particular failure mode should the instrument air supply fail for any reason. The most common control valve actuator used in the industry is the diaphragm actuator. Diaphragm actuators, as in the case of valve bodies, can be classified as either direct or reverse acting. Basic Types and Designs Any failure mode can be obtained with a combination of direct or reverse acting actuator and direct or reverse acting valve body. The two most common failure mode of control valves are: Air to Close Control Valve ATC An air to close ATC valve and therefore fail open valve, can be obtained with the combination of a reverse acting actuator and a reverse acting valve body or a direct acting actuator and a direct acting valve body.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity. There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing:

Stephen Kim Jun 28, Share View Full Gallery Nitrous bottles, big blowers, and lumpy cams are the usual suspects to look for when smoking a hot street car out of a dimly lit alley, but why not just look at the gauges? It’s the difference between maximizing performance and blowing up, but even street machines that rarely see track use need quality gauges for one simple reason: Factory gauges flat out suck.
Some of it has to do with antiquated sending units, and some of it has to do with suspect circuitry and decrepit wiring. To help us understand just how far instrumentation technology has come over the decades, and what kind of features are packed into the modern crop of aftermarket gauges, we interviewed Greg Karpe of Dakota Digital.

No, I’m not talking about the attractive person in the passenger seat, but rather the car’s dash and instrumentation. As a driver, you likely don’t even realize how often you steal looks at the instrument panel, quickly checking speed, rpm, or other engine functions before returning your attention to the road. Thanks to some careful planning, the instruments in a Corvette-even a ’71 Stingray like Project C3 Triple-Ex-are placed so as to give the driver as much information as possible in the shortest time, with minimal distraction.
At a time when many manufacturers were producing massively powered beasts of cars with a sweeping speedometer, a minuscule tach, and often just a light to tell the driver when oil pressure was lost, Chevrolet did an excellent job of providing full, easy-to-read instruments for its flagship performer. But while proper gauge placement is critical, it’s even more important that the instruments monitor engine and speed functions accurately.
Unfortunately, the electric engine instruments installed in early Corvettes-along with the somewhat antiquated cable-driven tachometer-often work poorly or not at all, potentially leading to outcomes ranging from a pricey speeding ticket to an even pricier engine failure. While we’re exaggerating a little here, knowing that your gauges work properly does instill a sense of confidence that your engine is operating within the correct parameters. There are always choices when it comes to the instrumentation in your Corvette, and returning the dash to factory specifications is certainly a good option for stock restorations or even mildly modified cars.

Automated production of Bill of Materials, Cable Schedules, Interconnection Lists, and more Drafting Services The Engineering staff in our Elecdes Manpower services department provide a comprehensive range of library building, database building and turnkey installation services for the Elecdes Design Suite software. Elecdes Manpower also supply resource for directly assisting our clients with the production of electrical engineering documents and cable routing, and have assisted in drafting the associated diagrams on many of the world’s major construction and engineering projects.
We have completed several projects with Elecdes and we are very pleased with how easy it is to use. Engineering Manager Manufacturing, St Louis We can produce an electrical scheme in less than half the time required historically. Much of the reduction was achieved in the automated generation of terminal strips and wiring diagrams. The software reduces human errors and is more precise.
The setup and prep time needed to autogenerate these drawings was dramatically less than it would have taken to manually draft them all. The others, 4 of them, produced loop drawings manually, and it has taken them 3 months. Engineer, Roche Energy Australia Scada Systems have always been keen to help and develop their software along with the client; this aspect is a key factor to give us an advantage over our competitors.

In my installation the new trailer wire harness is supplied with volt power for the trailer battery bank position 4 in the diagram from the distribution hub in the storage compartment. Typically, you would tap the output of the alternator to supply the trailer line. You would use a battery isolator or a solenoid to separate the banks – really only required if you keep the trailer and truck plugged together for long periods.
If you really want to get fancy you could use a “smart” charging switch, or a cross-charge regulator in place of an isolator or solenoid. This would ensure that both the truck and trailer battery banks get a full charge off the alternator. If you don’t use a “smart” charging switch then the alternator will shut down when the first battery bank reaches the cut-off voltage of your truck regulator.
This will leave the other bank typically the trailer bank without a full charge.
