Product Description of Ball valve for heating supply:
Technical introduction
★The ball valve is designed as fully welded structure,which can prevent the leakage of medium.
★The valve seat is floating and spring-loade.The seal is made of soft seal materials of PTFE+20%C and Viton B.The seat is tightly abutted against the ball surface by the pressure of a spring,so that even if the media is in low pressure,a reliable sealing can be assured for the ball valve.Double piston effect and double seal(two-seal seat)are adopted in specially designed valve seat to realize double sealing,which makes the tightness of the ball valve more advantageous and the operation easier.
★A floating ball is adopted for DN15-DN200,and a stem and trunnion ball is adopted for DN200 and above,which can ensure the accurate position of different size ball.In other words,the sealing performance,low torque valve and operability can be guaranteed.
★The sealing of the stem is fulfilled by two replaceable O-rings and packing consisting of PTEE+20%C or flexible graphite,as the packing seal material,is fire proof effect,and is specially suitable for fuel gas systems.
★The materials used for the valve body and pipelines are the same(carbon steel or SS steel),valve body and stem adopt SS steel and the packing adopts PTEE+20%C which is corrosion-resistance or flexible graphite.

- Q: Among butterfly,ball,needle and gate valves which is used mostly in pneumatic system?
- I don't agree that gate valves operate quickly and that they usually don't leak. Gate valves are slow to operate specially in large sizes and they all tend to leak unless they have a soft seat and there are very few of these type of gate valves. In larger piping systems globe valves are used to throttle air but not usually as a on/off valve. Probably the best on/off valve is the soft seated ball valve. They work well regardless of size with very little if any leakage. You can get some butterfly valves with soft seats that are really designed to operate much like a ball valve but are only economic in large sizes. The disc in these valves is essentially a wafer out of the sphere and that is why they do so well.
- Q: How does a deluge valve differ from a standard alarm valve in a wet system?What are differences from a standard wet pipe system regard alarm trim and NPFA codesAlso if an existing system, over 2000sft, (pipe sched method) has no siamese connection, and I am adding addtional heads via the same pipe schedule method - Am i required to upgrade the riser/alarm trim to include a fire department connection? - (re:NFP13, 2002)
- Normally sprinkler can classify as either wet type or dry type. In which under the Wet type system you will have pre-action, deluge and Dry pipe. Of course in anycase wet pipe is the best due to its economic reasons. Indeed, ppl spec for dry type because of afraid fault alarm, accident damage, low temperature (maybe less than 10 degree C) of production area and so on and forth. Generally, deluge valve can be manual or automatic. It doesn't have sprinkler bulb head. Upon detection of fire, responsible person shall operate the alarm valve manually. If automatic features is installed, Heat and Smoke detector will detect the fire and trigger the alarm valve to open and the water flow in. You need to calculate the Design Density to size up your tank properly. In your case of just only an extension of building and not construction from empty land, you may need to study on the existing fire fighting system to which standard it has been designed from. From there, you can extend by maybe adding another alarm valve, and so on and forth. Mechanical Consultant will able to assist you in this. You may write to me and tell me more about the form, feed and funtion of the building so that i can provide more ideas on this....
- Q: Movers messed up the valve so hose won't screw in w/o leaking
- Buy a new valve at an appliance parts outlet. Make sure it's the right one. Many times they will come with instructions. Unplug the unit. Shut off the water and remove the hoses. Remove the back panel to access the valve. Remove the old broke valve and replace it with the new one. Replace the panel. Attach the hoses and turn on the water. Check for leaks. Plug in the unit and give it a test. Try all the temperature settings. Congratulations. You are now a professional..
- Q: My husband went to the doctor today, then called to say he won't be coming home because he has infective endocarditis. They sent him to another, larger, hospital in the region. Hours later he called and said that he needs surgery on the valve and they are moving him to another part of the country. I've been trying to read about it but I'm not sure I understand. What I've read says that they have to treat the infection with penicillin first, the he can have surgery. However, he's telling me he might have surgery when he get to the other hospital. He needs a new valve. Does this mean that his condition is worse than those I've read about or that they are simply doing things differently? Also, if you know. Does other illnesses make the risks much higher? He's got aspergillus in his lungs and have had 2/3 of the lungs removed. He has an immune deficiency (HIES) and he is physically weak from being sick. I know it's not good, but how bad is it?
- There are risks in any surgery - no matter how major or minor. Overall health condition also plays an important role in his recovery. Being he has an infection which could be life-threatening, treating him and having him go through this procedure gives him more chance of survival. The doctors have weighed the pros and cons of him having this procedure and feel this is the best way to proceed. They will do their best to help and take care of him.
- Q: I need to make a one way valve that would allow water or other fluid one way but if there is too much pressure on the opposite side the valve will close and stop water from flowing backward. Can anyone help?
- R V parts stores have an item which allows a garden hose to be connected to the RV but the tank water inside the RV is not allowed to come out of the RV and enter the water hose (supply) so only fresh water comes in, nothing goes out.
- Q: Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
- well really they should dont see the big deal they are like a buck each... and will take ten minutes to fix.. at any shop some places might cost you 10 to 20 bucks.. and yes if there is a recall on valve stems im sure they would redo them for free... . ive never heard of one been doing tires over 20 yrs.... rubbber gets old and dry about as fast as the tires wear out
- Q: ex: 4 stroke 16 valve engine
- To give you an example: my car has a 4 stroke Otto cycle 4 cylinders engine. It has 16 valves. Every cylinder has 4 valves, 2 to intake fresh combustion fluid ad 2 for the exausts. It's a double over head camshaft engine (DOHC). A 2 stroke engine doesn't have valves as a 4stroke. In a 2 stroke engine (in Otto cycle, I don't know in Diesel cycle) the piston works as a valve. Take care
- Q: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?
- There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.
- Q: I was diagnosed with Mitral Valve Prolapse. Does anyone else have this? Does this cause panic attacks? I have heard that. What other problems does it cause?
- What is mitral valve prolapse? How does a patient with MVP feel? How is mitral valve prolapse diagnosed and evaluated? What is the treatment for MVP? Mitral Valve Prolapse At A Glance What is mitral valve prolapse? Mitral valve prolapse (also known as click murmur syndrome and Barlow's syndrome) is the most common heart valve abnormality, affecting five to ten percent of the world population. A normal mitral valve consists of two thin leaflets, located between the left atrium and the left ventricle of the heart. Mitral valve leaflets, shaped like parachutes, are attached to the inner wall of the left ventricle by a series of strings called chordae. When the ventricles contract, the mitral valve leaflets close snugly, preventing backflow of blood from the left ventricle into the left atrium. When the ventricles relax, the valves open to allow oxygenated blood from the lungs to fill the left ventricle. In patients with mitral valve prolapse, the mitral apparatus (valve leaflets and chordae) becomes affected by a process called myxomatous degeneration. In myxomatous degeneration, the structural protein, collagen, forms abnormally and causes thickening, enlargement and redundancy of the leaflets and chordae. When the ventricles contract, the redundant leaflets prolapse (flop backwards) into the left atrium, sometimes allowing leakage of blood through the valve opening (mitral regurgitation). When severe, mitral regurgitation can lead to heart failure and abnormal heart rhythms. Most patients are totally unaware of the prolapsing of the mitral valve. Others may experience a number of symptoms discussed below. The mitral valve prolapse (MVP) syndrome has a strong hereditary tendency, although the exact cause is unknown. Affected family members are often tall, thin, with long arms and fingers, and straight backs. It is seen most commonly in women from 20 to 40 years old, but also occurs in men.
- Q: I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.
- Mechanical valves require lifelong anti coagulation. This can cause problems of compliance (Forgetting to take the medicine), longer time to heal for cuts, and potential internal bleeding problems especially for women. They have a very long life. Current bio prosthetic valves have improved considerably in durability. They do not require continuous anti coagulation. They do tend to calcify. This may not be a problem 55 years and above. These valves also have better blood flow characteristics. These are the general considerations. Individual bio chemistries vary widely. Your surgeon and cardiologist are the best fit to suggest what is best for you.
