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:Question about variable valve timing?
Modifying camshaft timing under changing engine demand provides better balance between the following performance concerns: Engine power output Fuel economy Lower tailpipe emissions
Q:Is The EGR valve necessary?
when i used to modify cars/trucks.build high performance engines,the first thing to go was the egr valve.some places or states require an emissions test even on diesels.so if you do decide to remove the egr vale keep it handy to put back on.
Q:Sewer ejector check valve placement?
the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
Q:blowout valve for sti plz help!?
First I wouldn't purchase the Greddy, I had the former Type-S and it tended to leak on my 02 WRX. I would look at getting something like the HKS SSQV it is one of the most efficient valves out there, and if you don't like the chirp it makes you can purchase an insert that is a woosh of air. As far as what a Blow Off Valve does... When you throttle plate closes after boosting, your charge pipe(between the turbo outlet and the throttle) has leftover boost pressure. This pressure will push back on the turbo and possibly harm it. Factory this pressure is re-routed to the intake, an aftermarket BOV vents this into the atmosphere, making the desired noise. Yous can get valves that do 1/2 vent and 1/2 re-circulate. With a cheaper valve like the Greddy the vent into the atmosphere is going to cause the car to stumble between shifts, this is because the valve is inefficient and causes the vehicle to run rich. As far as Warranty goes, it is illegal for a car manufacturer to void a warranty do to usage of parts other than theirs. BUT if you need warranty work and they can without a doubt prove that the Blow Of Valve caused the damage they will make you pay for that damage. Tial is awesome, but fitment on TMIC would be an issue.
Q:Leaking metal Tyre valve stem?
The leak is caused by corrosion of the alloy wheel in the hole that the metal valve stem goes through. You might try to let the air out and loosen the nut on the valve stem and spray penetrating oil on the o-ring which is on the base of the valve stem and is what holds the air in. Turn the stem back and forth a bit to mave the corrosion and then respray the o-ring. Tighten the stem nut, inflate the tire to 35 lbs. and spray a bit of soapy water on the stem to check for leaks. If it still leaks you will need to remove the tire and valve stem,clean the hole and surrounding area inside the rim and clean the valve stem and replace the o-ring. If the valve stem is a pressure sensor type for the tire air pressure monitoring system you may need to reprogram it. Only use plastic caps on the valve stem. Metal ones corrode on the stem and wreck them and never come off.
Q:How do I fix a knocking valve?
Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
Q:valve mismatch?
Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
Q:In a car, whats a valve/cylinder?
There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
Q:i can't pump my presta valve...?
no longer understanding the make of motor vehicle i won't be able to be particular. A valve cover is a straightforward bolt on area. maximum engines won't require an outstanding form of different areas to be bumped off yet that may no longer consistently the case. purely get rid of the bolts/screws protecting the valve cover on and carry it off.
Q:Tricuspid Valve Question?
if actuality be told whilst your valves close, there is a few returned pass instead of all your blood being pushed forward.. gentle regurgitation often does not reason challenge, yet you may get regarded at each year to visual show unit if it gets worse or no longer. you does no longer ought to get valve replace surgical technique till it extremely is reasonable to severe. if so, you will have the flexibility to observe with the aid of fact it could reason shortness of breath and because your blood pass isn't optimized.
