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.

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 couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
- I dont think they sell just the top plate by itself even if you could determine the mfgd. Cut out the entire old valve and replace it. Its not that big of a job.
- Q: I know absolutely nothing about cars. My AC stopped working, I had a new air compressor, drier, expansion valve put on. It was also vacuumed out. Problem is it will not take a recharge, and there is no refrigerant in it at all. But it keeps reading high pressure, I don't know the readings I was told it is reading high, and will not take a recharge. Someone on yahoo answers suggested it might be the Schrader valve is this a problem that it can cause if it's bad that it will not let you recharge, and read a high pressure reading? Is there a Schrader valve for the low pressure valve amp; the high pressure valve or is there just one? I have a 96 Dodge Stratus ES. Thank you for any help or ideas.
- 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: I just got a new set of tired 2 months ago. The last 3 weeks I've had a separate tire go flat (3 in total). The last 3 the repair company said they were caused by cracked valve stems. So after the 3rd time it happened they replaced all valve stems on each tire. Now today I just got a 4th flat. That's 1 each week for the past 4 weeks. I'm taking into the shop this afternoon for them to inspect the tire. I suspect they will say it's again the valve stem. Any help on what I can do or what to say or ask to get them to fix the problem instead of just putting another bandaid on it? I'm very concerned about my safety and it really sucks that everytime i get into my car, I have to wonder, am i going to get a flat tire today...
- if you are running hub caps then maybe they are cutting into the valve stems. try running without hub caps and see if they crack.
- Q: So i was driving down the highway and my car just turned off. I turned the key but nothing. My lights were on and everything. I took it to a repair guy and he told me that the timing belt was broken, so i paid to have it fixed. Then he told me something about a compressioner or something, i paid for that, then he told me the valve was bent, so i was pissed and said i wouldn't pay. He was going to charge me about 550. I had already paid him about 250. and i think he was scamming me was I wrong? Does that sound right? Also how would I go about fixing?
- check to see if the motor is a no-tolerance engine. You would bend a valve if you broke a timing belt. This is why Honda, Mitsubishi, and many others warn you to change the timing belt at about 60-75K miles. $250.00 for a timing belt installed is on the low side for cost.Call a dealer for the make of car and ask the service manager if the motor is a no-tolerance engine. If it is you will have more cost before the motor is running.
- Q: The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?
- it is a good suggestion. perhaps someone would take steps to implement it.
- Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
- Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.
- Q: My vehicle has 160,000 miles and has burned 2 quarts of oil at 3000 miles. Someone told me to change the PCV valve because sometimes a bad PCV valve can cause oil consumption. I appreciate your assistance.
- A PVC valve, or anything else for that matter, for a vehicle with 160,000 miles on it that's losing that much oil is probably a bad investment... A rebuilt motor might be a good investment if the rest of the vehicle is sound. If you're not willing to do that, any other shiny new part you put on will end up in the junk yard.
- Q: Can a clogged EGR regulator valve cause my car to stall out and die when it's idling at red lights?If I give it a little has it wakes the car up and keeps it from dying.One mechanic told me it was clogged up and that it can cause that issue. My boss says there's no way that's the problem... I say we've fixed cleaned or replaced just about everything else...Is this true or is the mechanic just trying to pocket a bit more $$??
- No, there is no way a clogged EGR valve can cause the car to stall. The EGR valve is only supposed to open and allow flow when the engine is under load so if it's flow is stopped all the time it behaves no differently at idle than a new valve. HOWEVER, if the valve is dirty or carboned up and the valve is getting sticky and not closing all the way when it's supposed to then it can cause a stall. Do you know what kind of car it is? Update: It's a 2002 ford focus wagon These cars have a very common problem with stalling and it is usually caused by rotted out rubber elbows on the PCV valve vacuum lines. If you follow every inch of the PCV hard lines there will be at least two rubber fittings on either end of the system, poke your fingernail into the corners to see if they have gone soft and cracked.
- Q: im trying to turn on my sprinklers from the valve manually,but doesn't seem to work, the valve it's an antisiphon rainbird valve with two little knobs, I know that one is the bleeder and the other the pressure control, or something like that, and the solenoid has the on and off arrows on it, but i can't do it anyways,they come on automatically right on time ,it's just the manual thing that i can't do, please help me,i really need it
- Here's okorder /... Simply twist the solenoid (the black cylinder with 2 wires coming from it) on the valve counter-clockwise 1/4 to 1/2 a turn. To shut off the valve, twist the solenoid clockwise until it is snug on the valve. Good luck!
- Q: So I just got mu egr valve on my car replaced a year ago. Now it needs replacing again!? why might this be? shouldnt it last longer?
- There is no guarantee on how long anything is going to last these days. Yes ideally they should last longer but yours didn't and it needs another EGR valve. sounds like a faulty unit to me.
