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.

                                             

Design Features  of Ball valve for heating supply:

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:Aortic valve regurgitation?
Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?

Q:How is heart valve dysfunction measured?
Initial auscultation of your heart sounds can determine the presence of murmurs which are indications that valves are not closing properly (leaking) and allowing the heart chambers to fill and empty properly. Usually once murmurs are detected, an echocardiogram is done to visualize the valve function. From this test gradients can be determined to assess individual valve functions. The higher the gradient (it's a calculation based on blood flow and pressure across the valve leaflets) the worse the valve function. Mild gradients are not considered serious and are usually just monitored with your regular checkups to see if they are worsening. Serious gradients indicate poor valve function and are usually corrected with either valvuloplasty or valve replacement. Serious valve impairment also has associated heart symptoms such as congestive heart failure, left ventricular hypertrophy, arrythmias, and poor ejection fractions-to name a few. Regular follow-up is suggested with your cardiologist to monitor any potential deterioration in your valve functions. Meds are often used to treat the symptoms of poor valve function not to cure your valves. Once damaged, heart valves do not repair themselves. The aim is to reduce the workload put on the valves and prevent their function from declining further. Hope this helps.
Q:what is an air control valve, used for air line tubing?
The air control valves are to control air flow rate going to the filter/device in the tank.
Q:Valve cover gasket leak?

Q:I need help with my trumpet/cornet valves?
Every trumpet I've used has numbers on the valves. These should be facing you when inserting the valves, valve 1 being closest to you, and valve 3 being closest to the bell.
Q:Valve amps?!?
Marshall were big name in Amps when pretty well everything electronic used valves. Some valves were quite small, some larger, and some are still used today in powerful transmitters. There are those who swear that the sound produced by a valve amplifier is far better than a solid state one. Valve technology takes up much more space than solid state, so miniaturisation is a problem, and also uses much more power and produces a lot of heat. Now solid state is capable of producing high power audio amplifiers which use less power and take up less space, so have become the preferred method. Nevertheless, there is a strong following even today for a good high powered valve amplifier. And yes, it is quite possible to have a valve and solid state mix. The solid state works at the input stage, and the valves take over at high power output levels, but I am not sure what the purists would think about this hybrid usage .
Q:Vauxhall Vectra EGR valve replacement?
The EGR on this model is indeed vacuum operated. The diaphragm rarely fails to be fair but that particular engine suffers with vacuum leaks. This is something that needs checking first. Also, before buying one, try sucking on the little vacuum connection going into the unit first. You should feel resistance as the plunger is sucked up against spring pressure. If no resistance is met, the diaphragm is gone and it needs replacing. If you can feel the plunger lifting, there is nothing wrong with it. You can remove it to make it easier. Push the plunger in by hand and put your finger over the vacuum connection; the plunger should stay where it is until you take your finger off. (It's hidden under the plastic cover on the top of the engine (3 Torx bolts) and is easy to access.) The EGR valve unfortunately comes with the inlet manifold (expensive) which would mean removing injector pipes etc. if you fit it all. It is, however, very easy to replace if you just remove the 2 bolts holding it into the inlet manifold. They are female Torx but an 8mm 6 point socket will work too. Any other questions on this job, just ask or email.
Q:mitral valve prolapse...?
Mitral valve prolapse does not usually cause the painful symptoms usually associated with a heart attack. Depending on the severity it can cause dizziness or fainting on rising from a seated position. If you press on the left carotid artery, reducing blood flow to the brain a mitral valve prolapse condition will not be able to overcome the extra resistance applied to the artery and may cause a blackout. This depends on your exact condition. It can be corrected by surgery with either an artificial or an organic valve replacement. The chest pains may be something else going on with your heart or just caused by anxiety and stress. I believe it would be best if you went back to the cardiologist and had him/her check you out thoroughly. If only to set your mind at ease and relieve some of your anxiety. Take care
