High Performance API Pilot Operated Pressure Relief Valve

HTXD pilot-operated safety valves are designed and manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section VIII. They are composed of a main valve and a pilot valve. The pilot valve automatically responds to the pressure change of the system media to control the open and close of the main valve. This series of safety valves suit working conditions of high back-pressure, large flowrate, high pressure, strict sealing requirements and compact installation location.

Product information:

Size: 1" D 2"-8" T 10"
Pressure:150 lb-2500 lb
Temperature: -29-+260°C

Performance:

The allowable tolerance of the set pressure ≤± 3% of the set pressure

Overpressure: ≤ 10% of the set pressure

Blowdown: ≤ 10% of the set pressure

Tightness:The valve have good seat tightness,conforms to API Std 527

Product Feature:

The soft seat design provides good seat tightness before and after each relief cycle
The system can be operated nearer set pressure without valve leakage
No more overpressure required for full lift of main valve
Proper valve operation and lift are unaffected by back pressure
Adjustable blowdown
Non-flowing pilot reduces product loss and environmental pollution
Quick simple verification of set pressure while valve remains in service

Q:Can anyone recommend valve manufacturers who make a good electric high temperature valve. The temperature that I am looking at is 1600 F at 100 psi. It should be electric magnetism controled. Is there anybody know what is the highest temperature the valve can bear in the world?: google 'inconnel valve' look for foundry equipment suppliers Can you valve the gas away from whatever is hot, or is your gas at 1600 F and 100 PSI ? If so, what are you using for piping ?

Q:Describe a typical semilunar valve and tell how it works: The semilunar valves are located between the aorta and the left ventricle and between the pulmonary artery and the right ventricle.(aortic valve and pulmonary valve) The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out. They are shaped like a half moon, hence the name semilunar (semi-, -lunar). they prevent the back flow of blood to left and right ventricles respectively.

Q:Bought a 1986 GMC 350day 1 started up good - idle was rough - idle really too low, when brakes where applied, it would backfire. (day 2) Changed oil which was really dark - oil filter too... ghanged spark plugs and wires. % 10 improvement... Engine lack power and vibrates but no more backfire.day 4 Changed Cap and rotor - % 30 improvement - day 5 Got the manifold gasket replaced. Same condition but silent... day 6 Changed coil in cap ... Changed fuel filter % 60 improvement... The thing ran like new... Full power I started beliving again..Got full oil pressure 300 kpa - no valve noise Ran 30 minutes on highway.... Valves started making noise especially on driver's side... Engine lost lots of power, and vibrates a lot... doesnt heat up to much but oil pressure seems very low. (day 7) Start up the thing, and even when cold and choke on, oil pressure not as good as in the beginning. What went wrong: What went wrong? Bought a 1986 GMC 350. Solution? (day 8) buy a Ford

Q:where is the bleed valve in a 97 taurus????thank you: On virtually every modern car radiator it is at the bottom of the radiator on the engine side.

Q:I need an angle valve for my sink buts its a bit of an odd size. I have copper tubing at 1/2 i need a valve preferably compression that can feed to a water supply that is 1/2 Pipe thread.Included images of the supply hose valve to sink. To help show what i'm looking for.: If you're looking for a valve that attaches to a 1/2 iron pipe coming out of the wall, and then will feed to 1/2 copper tubing, then you're looking for- an angle stop, 1/2 female iron pipe to 1/2 compression. Just about any good hardware store will have it in stock or be able to order it, just be sure that they know what you need. I've often found that using visual aids,like a piece of pipe in one hand, and a piece of tubing in the other, with an empty space, waiting for a valve, between them, can be an invaluable aid to communication. Don't even try to cut and adapt a braided hose. The stainless braid contains a (relatively thin) rubber hose. Without the braid to reinforce it, it will burst. If you need to adapt plumbing, there is always a way to get water from point A to point B. The challenge is finding the most elegant route.

Q:My boyfriend is getting mitral valve replacement surgery soon, he is getting a mechanical valve put in.Has anyone had this surgery done? What are the risks. Anything else need to know about this surgery that is important. Im just worried about the surgery wanting to know as much as I can to be prepared. thank you: Haven't had it done before but: It's a pretty involved procedure. Patient is put under general anesthesia and is usually on the cardiopulmonary bypass machine (heart-lung machine) since you can't really replace a heart valve if the heart is beating. mortality for full valve replacement according to wiki is 6-8 percent, prob less than 5% for young healthy patients. Recently, many people have been doing the procedure laparoscopically. Patients are put into the surgical ICU for typically 1-2 days after the surgery. You can be discharged about a week after. Obviously there's risks, this is a very involved and definitely not a simple procedure. However, the cardiothoracic surgeons do these procedures every day for their entire lives-they're very skilled and qualified. good luck!

Q:I got a new gas stove, but I can't find a shut off valve to take the old one out and put the new one in. There isnt one behind the stove on the line, and i went under the house and followed the gasline and didnt find one down there either. Can any one give me ideas where else to look?: call the gas company and they can help, probably shut the gas off at the meter

Q:emission control valve toyota camry: Is English your first language? Where is the question?

Q:does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?: Yes The valve causes your rear brakes too apply before the front brakes .Safety reasons,(If your fronts apply first chances are the rear of the vehicle could come around on you) It utilizes spring pressure and offset valving. There is a rubber button that you must depress to bleed the rear brakes It's an override.

Q:I have a 4 diameter column of water 10' tall (filled with water). I need to find a flush valve unit to fit into the bottom of it so that it will flush all of the water out of the column in 1 flush. Essentially this will act as a large toilet but it is for a design project at school. My concerns are that the flapper will close before the water is completely flushed out of the column. Is there any way I can make the flapper stay open thus flushing all the water in column out without holding the chain connecting the float to the flapper valve?: This is an interesting problem. I suggest you study the action of a toilet flush mechanism. Don't have the flapper on the outside, have it on the inside at the bottom of the column, in a small chamber. Use a flapper of very light material, such as a ping-pong ball, which will float on almost no water. (You don't say how fast the column has to drain.) A thought just occured - if the flapper were actually a floating ball, you could pull it up from above, and it would rise to the surface, then follow the water level down, and close it when empty with only a trace of water remaining. I can think of no simpler way to accomplish this challange. Good luck with the project.
