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:How can I stop my cornet valves from sticking?
If the valves continue to stick after being oiled, then it's time to clean your horn. Remove all the valves (making sure to keep them in order so you don't put them back in the wrong casings) as well as the slides. Fill a sink with warm (not hot) water with liquid dish soap. Wash all the parts gently with a soft clean cloth. There are special brushes available at music stores for cleaning the insides of slides. After cleaning, pat everything dry, apply fresh grease and oil, and reassemble.
Q:Would a ERG valve cause sputtering or hesitating on my pontiac firebird?
An EGR valve being open will cause mostly idle problems and light throttle/initial take-off problems...mostly when you have a high manifold vacuum is when you end up with problems because of a sticking EGR valve. Just remove the valve and clean it by soaking it in something like B-12 Chemtool. I can garuntee you that valve is probably disgustingly full of carbon depending on the year.
Q:32 / 64 / 128 / 512 Valve Car Engine?
I'm sure they could if they wanted to. The problem is the more moving parts you have the problemms you will have and the more it will cost.
Q:what is an air control valve, used for air line tubing?
The air control valves are to control air flow rate going to the filter/device in the tank.
Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
The tyre should be fine, the problem is with the inner bike tube. It is useful to know what type of valve your bike tube uses. Schrader valves have a middle pin surrounded by an outer ring. Presta valves have a movable nut that allows you to inflate or deflate the tube. It sounds like your bike tube has a presta valve you have damaged the movable nut by loosening it a bit too much and/or being a bit too rough with it when using the bike pump. Unfortunately, it can't be fixed. If that is the case, you will need to buy a new bike tube (and keep a spare one handy as well) edit - That's weird, Schrader valves don't usually do that. It must have been an old tube or a faulty one. You'll be needing a new bike tube. edit - Well, I didn't know you could fix them, but still it'll be less hassle if you just brought another tube.
Q:would EGR Valve Temperature Sensor make a car run lean?
Cadillac converter
Q:What is trumpet valve oil made of?
Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.
Q:Water heater relief valve leaks around threads?
lift few times pressure relief release, just to check if it is not jammed and it is not holding too high pressure. 1. prepare thread tape or goo, if no experience - goo is better, available in hardware and plumbing stores, you need just few drops 2. cut off water supply to the heater 3. relieve pressure in the heater (just open any hot water tap (fawcet) and let water out) 4. remove the valve completely, 5. with wire brush clean the thread, check for damage to the thread on the cistern as well and clean it too 6. wind several layers of teflon tape or well grease with plumbers hot water goo 7. remount the valve 8. close hot water tap which was used to release the pressure 9. open water supply to the heater 10. open hot water faucet to let the air out, close when stop gurgling and water pour out 11. check for leaks, if no leaks - JOB WELL DONE! 12 if any leaks find, repeat 1 to 4, wind few more layers of teflon tape, if goo was used - you need to use tape as well then. 12. repeat 7 to 11 and that is all...
Q:Valve covers leaking on my 75 VW Bug?
I accept as true with air cooled yet would upload this- Re-torque the heads and rocker palms earlier you re-alter the valves. be confident to alter this all with the engine chilly.The gas pump in this is electrical powered and does not have a splash ball and is no longer low priced to swap. I doubt it extremely is suited. generally the coil is sweet or no longer yet verify this run it interior the ineffective of night and look on the engine merely to establish to do no longer see any leakage of modern-day any the place. If there is an argument you will see sparks around the coil or wires.
Q:Control valves used in oil industry?
There are other manual control valves and on/off automatic valves that are used a various places for remote or emergency control. These can be globe, gate, ball, plug or butterfly valves. They can be actuated by pneumatics, hydraulics or electric power.
