Product Description:

Ball Valve For Heating Supply

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.

Features and Applications

Raymond's fully welded ball valve for heating supplyand Fuel Gas systemare used to control the flow at fully open or closed position,not regulate the flow.Only special types of ball valves can realize the flow regulation.Therefore,our welded ball valves can satisfy the requirements of heating systems,e.g:
Main pipelines of heating equipment
Cross channels of heating pipes
Heat exchanger station and any long distance operating station,e.g:
For the transmission of hot water and two kinds of mixed media(water,air or natural gas),limited to Max.4.0MPa and 200°C.
For the transmission of natural gas and one medium,from -30°C to 60°C,and even up to 150°C using specially designed ball valves.
Coal gas pipelines,trunk and the branch supply lines.

Q:How to control fluid flow through a valve automatically? What are the circuit requirements?
Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.
Q:All the Valves of the Heart?
the bicuspid is the same as the mitral valve it seems like anatomy has 12 names for everything In anatomy, the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. They are mechanically similar to reed valves. There are four valves in the heart (not counting the valve of the coronary sinus, and the valve of the inferior vena cava): The two atrioventricular (AV) valves between the atria and the ventricles, also called tricuspid and bicuspid. The two semilunar (SL) valves, in the arteries leaving the heart, also called pulmonary and aortic. This I know for sure. Drawing pictures always helped me keep it straight and I just got an A in anatomy. best of luck to you
Q:shuttle valve location?
The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
Q:What are the reasons a Schrader valve might need replaced?
After replacing all these parts it should have corrected any restriction. If it was vacuumed out there should be negative pressure in the system and accept a charge through the low side port. If you did not see the actual work done im wondering if the parts were indeed changed?
Q:Has anyone ever had Aortic Stenosis Valve Disorder or known anyone who has suffered from the condition and
There is a bloke just up the road from me had this procedure done about 3 years ago, and seems to be having a normal life. However, he is restricted on the use of strength. he was a carpenter / joiner which he has had to give up (He is in his mid 60's) Have you tried Wikipedia?
Q:What are Atrial valves?
By atrial valve, I assume it meant the atrioventricular valves. Basically, in the heart, the blood flows from right atrium, right ventricle, left atrium, left ventricle. The atrioventricular valves are the tricuspid and bicuspid valves. They make sure the blood flows from the right atrium - right ventricle and left atrium - left ventricle respectively and prevents blood from flowing the wrong way in those chambers.
Q:mitral valve prolapse syndrome?
Mitral valve prolapse is known to lead to chest pain, but the exact cause for the chest pain is not understood. The chest pain related to mitral valve prolapse is described as atypical, because it does not have the typical characteristics of other heart related pain. It is possible that your chest pain may or may not be related to your mitral valve prolapse. Chest pain that occurs or worsens with breathing is suggestive of a problem with the lining around the lungs (pleurisy.) A musculoskeletal cause like a pulled muscle is also possible. Anxiety would also be a possible cause. None of these conditions are serious. Chest pain resulting from MVP is not known to lead to any negative health consequences. Discuss it with your Cardiologist if you remain concerned.
Q:What would valve seat faulty will cause my h22a?
If the valve seats leak it will cause oil to run down the valve stem and either it gets sucked into the intake or it get pushed out the exhaust, depends if both valve stems are leaking. It would be black smoke not white. Your car will produce water in the exhaust system when exhaust goes through the cat converter this may come out as a white smoke but it should not be something you can see if your driving. If it is that much you have a head gasket problem.
Q:Bicuspid Aortic Valve...?
My daughter was diagnosed with this same thing when she was 10 days old. It has been a miracle that she has not needed any medication or surgery. She meets with the cardiologist 1 time a year. They told me if she stays as stable as she is she will not need surgery. Maybe if your condition stays as stable as it is now, you will never need surgery. I know that when they repair a VSD they do open heart surgery and put a patch over the hole that is in your heart. Sometimes these patches fail and they do surgery 2 or 3 times and it is common. I know that Bicuspid Aortic Valve is an inherited abnormality and that it becomes more sever in your 30's and 40's. Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement in their third or fourth decade of life. Patients with bicuspid aortic valve should be followed by cardiologist or cardiac surgeon with specific interest in this valve pathology. Average lifespan is similar to that of those without the anomaly. In many cases, the condition will cause no problems. However, especially in later life, a bicuspid aortic valve may become calcified, which may lead to varying degrees of severity of aortic stenosis and aortic regurgitation, which will manifest as murmurs. If these become severe enough, they may require heart surgery. I hope this helps and good luck with everything.
Q:In aircraft reciprocating engine, if valve spring surge happen?
Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough
