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.

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:what exactly causes a valve to stretch?
- It is probably a combination of the above answers, plus heat. I would think heat is the primary cause of the stretch. As you know metal expands, when it gets hot. It will also shrink when cooled. There is probably a point where they will only shrink back to a certain spot and still remain in the stretched position.
- Q:I got a 2012 peterbilt 386 ...it just came back from the shop a few day ago to get injectors 4 and 5 looked at and repaired ....I'm getting a fault code for injector spill valve and a engine light ....I tried resetting the computer to get rid of the code but that's not it ... uld timeing of this cause the problem ...but other than that it runs like a champ so what could I do to fix this is it time cause I did probably get re timed when they repaired it
- The fault for the spill valve is not something you can correct with timing. When they repaired or replace injectors they need to be programed into the computer so they match the other injectors. The spill valve is in the injector and is there to return unneeded fuel back to tank. If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back.
- Q:I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
- For 1 how do you know it has a stuck valve , if you know that you know how to get it unstuck (pb-blaster ) or something like that , or is it carbon holding it open if it is you will need to pull the head becouse the head of the valve will come off and damage the piston and the block , good luck.30 years exp on cars and big trucks
- Q:i heard i should get one rather than a Dump valve, well?, should i?
- Depends on the fuel injection system you have and whether or not you want it to make noise or not then a dump valve it is.Now,we need to know what kind of fuel injection system you have.If the car has a mass airflow sensor then a dump valve will not work.You see,all the air that enters the motor must be metered by the MAF sensor.If you have a dump valve,when you let of the gas,the pressurized air is vented to atmosphere.The engine control module is expecting X amount of air to enter the engine.It just got released to the outside.see the problem.
- Q:my Hunter SVC VALVE will not work with my Lawn Genie Valve. Is this becaous the voltage is not matched? Hunter says it operates solenoids at 6-9 v DC // Lawn Genie says it is an 18 v DC solenoid. :-( my original Hunter Valve broke and I replaced it with the Lawn Genie. Should I get a Hunter Valve , or a Lawn Genie Controller at this point/ or is there something I have overlooked?.
- Your Hunter transformer only provides about half the voltage needed to operate the Lawn Genie solenoid. You might find a weaker spring for the LG solenoid, but the long term fix is to stay consistent. Either use all Lawn Genie, all Hunter, all Rain Bird, etc.
- Q:My mom just went to DR and will have open heart next Thursday for removal of anyerisum. She was told she has 2 heart valves instead of four. What does this mean? Is it normal?
- Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.
- Q:Hi,I have just bought a Northface Hammerhead and for some reason when biting on the bite valve no water is being released. Does anyone have any idea why this might be, or can tell that I am missing something obvious. Thanks very very much.
- Some valves are finicky as to where you bite them. Also, sometimes blowing a small puff of air into the bladder will help the water flow faster. If you can't stand the valve you have, you can buy a replacement valve from another brand and stick it on there. My favorites are the MSR and Nalgene/Jansport valves, but Camelbak isn't bad either.
- Q:I got a french horn, but don't know if I can just use the valve oil I use for my trumpet. please help, thnx in advance :D
- Simply said: nope
- 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?
- You are looking for whats called an RP or back flow device. These may be sold at home depot. However, I know your local plumbing supply house would carry them.
- Q:I have an above ground water pump. there is good pressure(40), but the pump does not stop. Pump co did diagnostic test and said that foot valve needs to be replaced. The company charge me $399 for diagnostic test and and about $2200 for the foot valve replacement. It is reasonable.
- Yes, considering they have to pull all the pipe in the well to get to the foot valve which is at the bottom of the well.
