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:when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.
- SHUT OFF WATER AND REPLACE RELIEF VALVE, IF YOU HAVE HARD WATER IT CAN ACCUMULATE LIME AND FORCE VALVE TO OPEN. ALSO HEATING ELEMENT MIGHT BE BAD AND WATER HEATER IS OVER HEATING. VALVE SHOULD RANGE FROM 150 TO 210 PSI NOT 30 PSI.
- Q:I am a junior piping engineer. I want to know what is the meaning of term Triple Eccentric in Triple Eccentric Butterfly ValveButterfly Valve. So kindly enlighten me.
- Above answers your question. I've used these and they work great. But they cost much more then your tradition quarter turn butterfly valve.
- Q:how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
- First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
- Q:sprinkler valve leaking
- Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.
- Q:im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.
- look on the valve covers.it will be at one end with a hose running to the carb.
- Q:why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?
- Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.
- Q:I think they need to be taught how to count. Honesty... Half-Life, Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two... Where the hell is 3 already?
- Supposedly Valve is doing another Counter-Strike and will then shift their focus towards the Half-Life series. They have said repeatedly that it's something they would very interested in doing, but they have never said one way or another that they are, indeed, going to make a Half-Life 3 at any point in the future.
- Q:My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.
- Sounds good to me,
- Q:I have an above ground water pump. there is good pressure(40), but the pump does not stop. Pump co did diagnostic test and said that foot valve needs to be replaced. The company charge me $399 for diagnostic test and and about $2200 for the foot valve replacement. It is reasonable.
- WOW! Just read my exact problem there...I do have a water feed and pressure build up to 40 psi BUT same here...Pump will not stop. About 8 years ago I myself with the help of some friends pulled the two pipes from the well bottom put all new fittings on. Replaced the pressure tank and installed brand new well pump. So from what I am reading here I am understanding it is the foot valve that is causing my problem now. So I feel I can pull the two lines (55') and replace the foot valve and hopefully this is my problem??? I noticed as long as the pump is left running it builds up 40 psi and we can run our water but at 50it is suppose to shut the pump down but will not...OK?
- Q:I experience a quiet ride on a kawasaki vulcan vn 2000 and clicking started at the end sounds like valves ticking sometine like 2 then 1
- Time to take it in for an adjustment.
