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

- Q: my inflatable kayak has a self bailing drain valve. it says to close the valve in lakes and streams to stay completely dry and open it in oceans or mild whitewaters.whats the point of this valve? i WANT water to come in??
- If you're out in rough water, such as in whitewater, water is going to splash up over the sides of the boat. If the valve is closed, then the water that comes in has nowhere to drain. Soon the boat will fill with water and get sluggish and possibly unstable. So you leave the valve open. But the problem with having the valve open is you will have a little bit of water coming up through the valve and into the boat. You won't have a lot of water come in because the inflatable floor of the kayak keeps you somewhat above the level of the water. But on calm water where you won't have water splashing into the kayak, you can close the valve to keep that tiny bit of water out too.
- Q: Is there a devise to reverse the flow to a cylinder. Not the pump. But a inline flow deverter that would shift the flow from one side of the cylinder to the other at the end of the stroke automatically without a person interjecting.ie it extends fully then the flow reverses retracting it fully. Then the flow reverses, and it extends fully and so on.Preferably, with as little lag as possible during the transition.I want the pump to run constantly(not reversing) and the cylinder to run constantly. Do not worry about the heat generated.Would love something that ran off the main cylinder(like a secondary piston or valve that would opendivert flow at the end of the stroke) through linkage. But, I am open to electronics if need be. Further more want the return to be metered so that the push and pull forces will be the same(metered through a smaller opening to adjust for the rod).Thankyou

- Q: The hot water shutoff valve to the washing machine was dripping. I removed the packing nut and put in new packing over the weekend. Problem is that the packing nut seems to only go back on at an angle no matter what I do...it may have already been that way though. The valve isn't currently dripping, but I'm not liking the way the packing nut only goes on at an angle. Would it be crazy to keep the existing valve if I keep an eye on it and over time it doesn't drip, or is it too risky to keep this valve given that the packing nut is on at a funny angle? (Local plumbers here in Northern NJ all want around $350 if I were to replace both the hot and cold with a watts single handle valve.) Thanks, J.
- What type of pipe do you have? If it is galvanized steel pipe, shut the water off, drain the water, and remove the valve by turning counter clockwise. Apply some Teflon tape or pipe joint compound, and screw the new valve on. The valve is about $5 at your local hardware store. The Watts valve runs about $25, so the plumbers are trying to take advantage of you. If you have another type of pipe, just ask at your local hardware, and they will be happy to assist you. I would recommend replacing the valve. Water pressures fluctuate during the night, and build up to their highest point about 4am. If this started leaking at that time of the morning, you would wake up to a big surprise! I charge $85 for a service call, plus parts, for a comparison. Good luck to you!
- Q: its rated 120 VAC/26VA (3 prongs, one for ground) . I also have a horizontal level switch for liquid with rating 120 VAC/0.28 A (the switch will connect when the water level reach the target) normally open.How can I wire them so that when the level reached the valve will close and water will not flow into the tank? The switch is inside the tank and the valve connecting the pipe for feed water. Thanks
- considering your valve and turn is contained in the tank, why do no longer you in simple terms use a flow-activated valve and eliminate the electrical powered conclusion entirely? Why do you think of they use flow-valves in lavatories? because of the fact they do no longer consume any electrical energy and that they are undemanding units. considering you're no longer controlling a pump, why no longer in basic terms shop it undemanding?
- Q: What are the benefits of changing new cylinder heads and exhaust valves in the Main engine of the vessel? I am now studying a vessel which has a problem with their main engine. Frequent repair of cylinder heads (they usually weld it) and exhaust valves are the ones they do. I need to further give the benefits to be submitted to the vessel's management for them to buy new cylinder heads and exhaust valves as a replacement for the welded ones.
- To answer your first question only, the benefits of changing cylinder heads and valves would be to improve the overall performance of the engine, like increasing its horse power, speed and fuel consumption. To prove to the vessels owner that this needs to be done, a compression test should be done on each cylinder by a mechanic. This will show how each cylinder is functioning, and the results need to be cross referenced with the compression specifications for that specific engine.
- Q: Why do we use in chilled water pipe network utilizing 2 way valves on all terminals except the last terminal we use a 3 way valve, also another question what does a pump shutt off pressure means
- A 3 way valve has water continuously going either to the cooling coil or back to the return loop. This keeps a constant flow of chilled water available in the entire system for the coils to have chilled water immediately, when called for. Without the 3 way valve, chilled water would absorb heat while sitting the lines waiting to be used. Pump shut off pressure can mean the pressure for operating a switch on a water main so the line can not be over pressurized.
- Q: this valve uses in fire water lines...
- The question is not clear. What exactly do you want to know? There is lots of info online
- Q: I'm using a Yamaha double horn, and I reeeeeeealllyyyyy need to work on an audition for Monday. But my second valve is coming up slowly, which is a huge trouble 'cause all the pitches sound wrong!What do I do? I tried oiling the valve, that hasn't worked.
- Your second valve sounds like its gummed up. This can happen when the slide grease from your slides is washed into your valve. The greasy valve moves ok when there is lots of kerosene like oil to lubricate it, but when that oil dries out you end up with a slow moving valve. I had to remove my valves completely and clean them thoroughly to relieve my slow valves condition. Another less likely scenario is your valve spring is weak, or the valve string is not tight enough, but its much more likely that its due to insufficient oiling and/or a gummed up valve.
- Q: My washing machine had hot and cold water, but was leaking. I changed the inlet valve which stopped the leak, but now I have no hot water. When I put the setting on warm, the cold water runs for a bit. Then stops and no hot water comes. Any help?
- I suspect the leaking valve that was replaced was your washer's solenoid valve. Did you remember to turn the hot water supply valve on after you finished? That is the valve, next to the cold water supply valve, on/at the wall behind the washer. There are rubber hoses coming from those valves to the solenoid valves on your washer. If you forgot to turn it back on after replacing the leaking valve you'll get no water. If you turn off both the hot and cold supply valves on the wall you should be able to remove the rubber hoses right where they connect to the machine and check the water flow by directing them into a bucket or pan while you open the supply vales. If you have good pressure and flow make sure there is no debris clogging the screen, just inside there the hose connects to your machine. These can get blocked where the water won't pass or runs very slow. Sometimes it pays to check the simplest causes first. Good Luck. SS.
- Q: what is the purpose of valves such as: gate valve, foot valve and globe valve in the industry?
- Valves are used to stop/start or control the flow of liquids or gases in pipes. There are many many kinds of valves, so if you want info on a specific type, just list that.
