Product Description:

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

♦ 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


♦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:stop intake valve leakage in auto?
I think your confused. The intake valve lets fuel and air into the combustion chamber, there is no antifreeze held in by the intake valve. If you have an antifreeze leak that is visible on the outside of the engine, you can trace the leak to the source of he leak and repair it. If you are not mechanically inclined, I would take the vehicles to a reliable shop. ASE Master Tech 30 + yrs. Retired.
Q:Help With My EGR Valve?
EGR valves are replaced much more often than they need to be. Most of the time the problem is not in the valve itself but in the EGR passages. The actual trouble code would verify that (I am expecting a P0401: Insufficient EGR Flow). The most effective approach is to remove the EGR valve, examine it for really bad deposits, then clean it with carburetor cleaner or replace it depending on whether it looks like it can be cleaned. In any case, clean out all the exhaust side passages. The second source has the usual vague ehow instructions while the third source has a more detailed but vertiginous video. EGR valves are pricey enough (typically $150) to make it worth cleaning before replacing. I personally have never had to replace an EGR valve.
Q:Anyone know anything about mitral valve prolapse?
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:which valves on the mc are the outlet valves?
All hot water heaters have what they call Anode Rods For more than 60 years, it has been used as a key part of the rust protection of a tank. The rods are made of magnesium or aluminum that's formed around a steel core wire and is screwed into the top of the tank. A lot of the times they are on the hot water outlet. You should have a dielectric union separating the galvanized pipe on the top of the water heater from the copper pipe for your house supply. You should be able to remove the anode rod from the tank and get a replacement from your local plumbing supply store. Most likely the sediment/ hard water deposits have deteriorated the rod and have caused corrosive deposits to clog your lines.
Q:What do people mean when they say they have a 12 in valve?
A 12 inch valve means it is designed to fit with nominal 12 inch pipe. Most 12 valves are flanged so these valves would also be flanged to match as 12 piping flange. They would also be sized to match the appropriate flange rating as in 125#, 250#, 150#, 300# 600# and so on. As to the opening of the valve that will vary depending on the type of valve. For a gate valve it will be very close to 12 inch in diameter. For a globe valve it may be a bit smaller. In some cases you will see what it called a reduced port valve where in internal opening is smaller. This is more common with large ball valve where the smaller ball and opening makes the opening/closing torque less. These valves also tend to have a venturi shape on the inlet and out leading to be ball so the pressure drop is closer to a full opening valve.
Q:96 saturn sl1 EGR Valve...?
i had one go bad on my 95 saturn, it sometimes ran rough at a steady speed and stalled at stoplights
Q:Silent sump pump shut-off valves?
If you mean the discharge check valve, it will clunk when the level switch trips the pump. The head or weight of the water trying to flow back into the crock causes the check valve to slam closed, making a clunking sound. This is pretty common and normal.
Q:What's a suitable valve for this scenario?

Q:what is meant by inherent characteristic for the steam control valve?
There are different type of valves, (ball, gate, globe, needle, diaphram) each have their own characteristics in how they operate and the effect they have on flow. Inherent characteristic would be an effect that valve has on the fluid flowing through it.(steam can also be considered a fluid ) An example is a globe valve used to throttle a flow does so by adjusting the size of its opening. In essense its a variable orifice. Flow through an orifice results in a pressure drop across that orifice. So, an inherent characteristic of a globe valve is a pressure drop.
Q:Trumpet valve stuck upright?
i got here across that Dennis Wick valve oil is a procedures more advantageous ideal to any that I easily have used. you'll locate it on Amazon. If cleansing with dish cleansing soap and heat water would not artwork, alongside with the Dennis Wick oil, I recommend that you're taking it to a restoration shop. be careful at the same time as cleansing now to not get any cork or felt moist. only dip the truly valve section into the water.
