Product Description:

Application:
A pressure relief valve (PRV) is a safety device that relieves overpressure in a vessel or system. When the pressure of vessel or system increased beyond the specified design pressure or maximum allowable working pressure, PRV will be opened automaticly to relief the overpressure for proteding the vessel or system. The PRV will be closed if the pressure reached specified design pressure so that to ensure the normal operation and protect the vessel or system.

Our Pressure Relief Valve has been designed and manuractured according to following Standard:

♦ ISO 4123-1 Safety Devices for Portection Against Excessve Pressure
♦ API STD 526 Flanged Steel Pressure Relief Valves
♦ API STD 527 Seat Tightness of Pressure Relief Valves

♦ ASME Boiler and Pressure Vessel Code Section VIII Division 1, Rules for Construction of Pressure Vessels

Peformance:
♦ Type: Conventional, Bellows

♦ Size:1" D 2"- 8" T 10"
♦ Class:150lb~2500lb
♦ Temperature:-268~+538°C

♦ Fluid: Gas, Steam, and Liquid
♦ Material: Carbon steel, Stainless steel, Alloy steel
♦ The allowable tolerance of the set pressure: ≤±3%
♦ Overpressure: ≤10%(gas)/≤20%(liquid)
♦ Blowdown: ≤10%(gas)/≤20%(liquid)

♦ Tightness: conforms to API STD 527

Features:

♦The solid nozzle is screwed into the body, which makes the maintenance easy.
♦ The shape of the disc holder has been designed to enhance the effect of the fluid thrust for an instant lift of the disc.
♦ Blowdown control is provided with adjustable nuzzle ring only.
♦ The adequate terials and clearance between disc holder and guide , spindle and adjusting screw assures disc to lift successfully.

♦ The surface of both the disc and the nozzle seat are deposited with Stellite. Excellent flatness and surface finish of the seating surfaces by precision machining and lapping assure pressure relief valve to have high degree of seat tightness and long using life.

♦ The bellows of balanced bellows pressure relief valves can not only avoid and effect of variable back pressure in the system , but also protect spring and other trim components from corrosive media.

♦ Materials are chosen carefully , and the manufacture of the spring and the bellows has strict technological process. Each of them is tested and checked strictly.

Q:Has anyone had surgery for Mitral Valve Prolapse?
costly Madam, i'm a heart professional sending this text for you. desire it enables you. Mitral valve prolapse, often spoke of as MVP, is a basic heart valve illness. The mitral valve is between the left atrium and the left ventricle of the midsection. It has 2 leaflets (flaps) that administration the blood pass. MVP occurs whilst one or the two between the leaflets are enlarged or have extra advantageous tissue. MVP is often innocuous. besides the shown fact that, substantial issues can ensue, alongside with a blood clot in the recommendations and an infection called infective endocarditis related to the mitral valve as nicely as different valves. MVP seems two times as often in women persons as in adult men. that's maximum regularly a hereditary illness. some those with MVP have not have been given any indications. besides the shown fact that, maximum sufferers adventure a speedy or bizarre heartbeat, shortness of breath, easy-headedness, and protracted fatigue. Many sufferers additionally be afflicted by migraines, eating and drowsing issues, an overactive or contaminated thyroid gland, diarrhea, and chilly arms and ft. Emotional rigidity often magnifies the indications. medical doctors usually prescribe prevalent exams and cardio workout for persons who've MVP. sufferers are additionally advised to limit their intake or use of extreme-carbohydrate meals, caffeine, and decongestants. some sufferers would want beta-blockers and specific antiarrhythmic medicine. extra severe circumstances will require surgical operation to repair or replace the valve or to insert an digital regulator, including a pacemaker or defibrillator.
Q:Sewer ejector check valve placement?
the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
Q:what is a foot valve used in petrochemical companies?
A foot valve is placed at the bottom of a suction pipe, which could be used to drain a large container of liquid. The foot valve is a one-way valve (check valve) that prevents the liquid from draining back into the container.

Q:bent valve stem?
Valve stems don't usually bend unless the valve hits a piston. I am assuming the rod that was bent was a push rod. The 5.2 engine is not an interference engine, so a cam timing problem would not cause the piston to hit the valve. I suppose that if you way over reved the engine a lifter could have pumped up and at a very high RPM the valves may have floated causing one or more to strike a piston. Push rods do bend for a variety of reasons, but to have a bent push rod AND a bent valve stem I would need more information to give you even an educated guess. You have the head off so look at the top of the piston and see if it looks like it was hit by the valves. Take the head to a machinist and have him check it for cracks and damaged guides. Have him check the valve spring tension also.
Q:Calculation of Shutdown Valve Instrument Air Supply?
Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
Q:new EGR valve?
i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.
Q:Electric supercharger. Blow off valves?
Hey guy. First off, you shouldn't even bother putting in an electric supercharger. The reasons are the about of boost you are going to need to see any REAL advantages you will not get from an elec. I suggest do what I am doing and spending the money to get a GOOD valve job and get everything polished to match and you will actually gain H.P. I have seen 32 hp gains out of a 2.2 I4 F2 engine from a probe by just adding a cold air intake, going to a 2 inch exhaust w/ header and a good valve job. Incidently, I now run 142 hp instead of the original 110.
Q:EGR Valve...?
if your talking about a car EGR valve, it's used for the smog system in your car...if you need help you need to specify what make and model of car you have... with a faulty EGR vale you will not pass a smog test and it will make your car run rough... go buy one at the local automotive store and locate it under your hood, they are very simple to install...
