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:Water shut off valve?
you should have a shut off where the waterline enters the buliding and 1 at the water meter
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:Technical requirements when deciding upon a control valve are?
1] I assume that by control valve you mean a variable orifice valve, not an on/off valve. 2] An answerer to your other question listed Metallurgy, temperature, pressure and shutoff requirement To which I note that if you need a tight shutoff you should not trust a control valve to do that, but should add an on/off valve in series. Also, metallurgy covers corrosion requirements but not obviously so 3] To which I add: flow rate [or Cv] and pressure drop fail open or fail closed response time signal input [3-15 psi, 4-20 mA, 1-5V, etc] connections [ie, fitting type] packed vs sealed might need to look at hard seat materials and/or replaceable seats, to control erosion reliability, ease of maintenance, availability of spares, timing on that vendor permanence [ie, are they entering bankruptcy ?] Cost
Q:Do blow-off valves cause problems in Audi tts?
Blow off valves are nice, but they aren't terribly good for your car. The main problem is that when the turbo isn't running, that open valve will suck unfiltered air into the engine and can seriously damage it. Blow offs are also pretty inefficient as you lose a good portion of the air in your turbo system. The best thing you can do is just get a good Forge diverter valve. Well made, looks nice, and will add a pretty decent amount of performance.
Q:Can I use a blow off valve with a nonturbo car?
lololol (not at question just at other responses). NO u can't dude, a blow off valve is a pressure release system for turbos, Its purpose is to prevent compressor surge, its is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged car when the throttle is lifted or closed, any built up pressure from the impeller once the throttle is lifted the blow off valve releases the air to the atmosphere, you can buy different trumpets for a different sounds effect, engines that are have a turbo but no blow off valve have what is called a diverter valve that recycles the air pressure back into the air intake... If you mean a Fujita SRI exhaust system then it will just have a nicer deep tone, not a harsh high-pitched sound like the other rice burner exhaust systems..
Q:Euphonium problem, valves?
There are several possibilities. You may have buildup on either the valve or the casing. Cleaning it thoroughly should normally remove it, but every once in a Blue Moon it pays to take it in and have it professionally cleaned. They can inspect it at the same time and tell you if you have a bend or a ding in the casing. Sometimes they are really hard to spot, especially if they are hidden in one of the crevices of the detail work. A really good repair person can stick a scope down there and tell you if you have some kind of blockage in just a few minutes. The only way to really clean inside the casing yourself is to get a good bottle brush that fits inside with just a little bit of resistance. You should really get someone to show you how to do it the first time because you don't want to go scraping up the insides. There is one other possibility that is kind of rare. Sometimes you get some gunk up under the valve button and it sticks when you push it down. You should normally be able to see this just by looking underneath however. Best of luck and I hope you find your sticking point and are able to set it free.
Q:Who knows anything about a leaking heart valve?
If the medical doctors say might, then he ought to get his valve mounted in might. think of approximately it. you could stay with purely area of your liver, purely one kidney, and you will possibly be able to stay devoid of your gall bladder. yet you could not stay devoid of your coronary heart, all muscle groups and chambers and valves! it particularly is not a sturdy time for him? What ought to probable be greater significant than getting his coronary heart mounted?
Q:99 eclipse bent valve?
no way to tell ...and he doesn't sand down the valve's called seating or lapping. and it's not done to the cylinder... knocking could aslo be a hung lifter.
Q:Which side is open for a pipe main shutoff valve?
You turn the valve counterclockwise to open or turn on the water. You would turn it clockwise to shut the water off. Think of it as you would as if you were turning a screw. Right is tight. Be sure you open the valve all the way so the packing in the valve is tight, some valves leak a little, especially old ones, if the valve is only opened partially.It pays to work a valve occasionally to keep it supple, otherwise the packing or rubber washers dry out and start to leak. When you are operating a ball valve, one with a flat handle that only turns 1/4 turn or 90 degrees, when the handle is going in the direction of the pipe, the water is on. When the handle is going across the pipe, the water is off.
