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.

FAQ of Ball valve for heating supply:
Q1:I can’t find the type of steel check valve which I need. what can I do?
The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.
Q2:Which certification do your products pass?
Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.
Q3:How can I place an order?
The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.
- Q: I am being sent for a level 2 Ultrasound Thursday because my previous US showed one of the babies valves was enlarged. She said all 4 chambers were there but she was very vague on what this means. Care to shed some light?
- I don't know what this means in a fetus at 20 weeks since a lot of changes still lie ahead, but you can glean some info from the nature of this type of defect in adults. If the abnormality doesn't change and if no other abnormalities arise, the flaps of the affected valve will poke into one of the heart chambers. This situation is called valve prolapse. Look up mitral valve prolapse as an example. Typically a valve prolapse is not a serious defect, but if the prolapse is severe it might require treatment at some point in life or maybe even multiple treatments. What the heart will look like at birth is probably the bigger question. Some abnormalities signal a genetic defect that might cause other problems as well. Some defects cause a chain of problems in later steps of development. Your doc should have a good idea if any of these concerns exist. Maybe genetic testing will be suggested, but many defects occur with no explanation and they do not cause other complications. I would guess that after the chambers are developed, a dilated valve would be unlikely to cause any significant complications in later heart development, but this is just a guess.
- 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
- even though this patent claims it will save money by eliminating a servo controller, it would seem to me to be an expensive item in and of itself. Other mechanisms would use linkages and lost motion to control a pilot shuttle valve. This would operate like the valve assemble for steam reciprocating pumps.
- Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles
- you cant drive w/ a broken valve lying around in the engine. but yes you can drive w/ carbon build up, it causes the engine to run a lil warmer and prolly acts as a oil seal to the piston even after the rings go out.and youve ran a lot of gas thru in 12 yrs so carbon build up is normal,valves dont always break tho unless you were giving it hell an it jus seen so much wear an got thin an finally broke.mayb its not jammed into the head and its jus broke
- Q: So i was looking for car parts and i was using my favorite website, and i was looking at turbos which are wicked costly. But i saw some blow off valves which i have heard about before. But i was wondering if you need a turbo in order to have a blow off valve installed into your car. And if you don't my next question would be is it hard to put one in and how?? Thank you for your time..
- A blowoff valve goes onto your intake or the piping from your turbocharger to make sure that you dont run to much pressure they are adjustable to whatever pressure you desire. Usually people running a positive displacement blower or a turbochargers run them. That being said I'm sure that you could put one on your car but without a power adder it would never blow off. Except in the case of a intake manifold overpressure such as a backfire.
- Q: according to my study only indurial gate valves have both rising and non rising stem through handwheel and it seems that it doesnot apply to golbe valve and globe valves are only non rising stem. i wanted to know if this is right
- The valve in the upper left quadrant of the picture on this web page is a rising stem globe valve. This type of globe valve is common in cast steel and forged steel valves like those used in the oil and gas industry. They can be as small as 3/4 up to about 8 sizes.
- Q: My cardiologist says I have Mitral Valve Relapse. She says MVR is when there is a backflow of bood entering the heart. When I checked online for MVR, I couldn't find anything except MVP (Mitral Valve Prolapse). What is MVR and how is it different than MVP?
- Mitral okorder /
- Q: I want to wash it but don't know what to oil the valves with because I was told not to use mellophone/trumpet valve oil so would the sewing machine oil be okay to use with out damaging me Horn?I not any other safe substitutions?
- If you don't get a good answer here, try reposting your question in Arts Humanities / Performing Arts - a lot of instrumentalists hang out there.
- Q: can you put a blow off valve on a chevy cobalt ss supercharged?
- Not unless it's turbocharged.
- Q: Could I get some possible remedies for Mitral Valve Prolapse pain? I currently am off beta blockers, and I need to cope with the mild, moderate to severe chest pain I experience. Female, average weight for my height, nonsmoker, maybe one alcoholic drink a week, exercise at least 3.5 hours a week. What do others with mitral valve prolapse do that helps?
- Weight okorder , why not try it, what have you got to lose?
- Q: I have a WRX. slightly modified. im getting some upgrades here soon. clutch, brakes, and catback exhaust. i have a blow off valve i bought a while back, but found out it was illegal here in cali. if you know about blow off valves, then respond. is it worth putting on? what are the consciences of having one illegally if noticed by cops? all i know is that it sounds bad ***! :)
- I doubt the cops would notice and if they do find out which is highly unlikely to happen you would just get a fix it ticket. i live in cali and i hear cars with blow off values all the time so my advice is don't trip and put it on your car. it will sound so bad ***!
