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:The pressure relief valve leaks on my electric water heater...?
You have already done what you are supposed to do. My only thought is that the thermostat on the heater is bad. I have installed hundreds of State heaters and the only problems I have ever had was a bad thermostat. Good luck. :) But be sure that you have an expansion tank on the heater. I forgot to mention that earlier. 70 PSI is higher than normal, but perfectly acceptable. I always have my house at 70 psi and no problems (also a State heater). I have a 50 gal heater.....I am not as rich as you are....LOL
Q:Radiator valve is constantly spitting water?
The little valve needs to be changed with a new one,that valve has a small leather inside and it is to spit out water and air until the leather gets wet ,and then stops, then when the leather gets dried out ,it will do the same thing again and again, This is a auto radiator air bleeding type valve used for many years in radiator heating systems................Ok.......Mel........ Hope this helps you...
Q:how many valves does a human heart have?
Everyone has correctly identified that there are 4 heart valves. The question of survival is producing a variance in the responses. This may be because you do not define what you mean by 'not functioning'. People may do reasonably well - at least initially - with varying degrees of stenosis and / or regurgitation of more than 1 heart valve. So Yes in a sense if I understand your question correctly a person may survive at least temporarily with only one heart valve functioning perfectly. Please bear in mind that you have not given much information for me to work with in answering your question. If I may be of further assistance please let me know. I wish you the very best of health and happiness and in all things may God bless. JR
Q:i want to know the detailed reason for pressure drops in expansion valve?
THERMOSTATIC EXPANSION VALVE A temperature-regulated valve that controls the amount of restriction to refrigerant flow between the receiver/drier and evaporator. Like the Fixed Orifice Tube, the Expansion Valve is the boundary between the High and Low sides of the refrigerant system. Unlike the Fixed Orifice, the Expansion Valve can regulate the flow of liquid refrigerant to the evaporator to either increase or decrease evaporator cooling based on the temperature of the refrigerant tube at the evaporator outlet. In vapour compression ref. cycle,The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. The auto-refrigeration effect of the adiabatic flash evaporation lowers the temperature of the liquid and vapor refrigerant mixture to where it is colder than the temperature of the enclosed space to be refrigerated.
Q:aortic valve with 98% gradient can be cured by body revive?
Can be cured by valve replacement... alternatively, if you can't/won't go through open heart surgery then you may be able to get valvuloplasty. A balloon is used to stretch the valve open. This does not last nearly as long as replacement, but avoids surgery. A third alternative would be to contact one of the percutaneous valve REPLACEMENT centers (Mayo, Cleveland Clinic, Columbia). This is an experimental procedure which replaces the valve using catheters instead of surgery. Advice offered here is not meant to be a replacement for proper evaluation and examination by a qualified medical professional and should not be construed as such.
Q:Trumpet Valves Question?
Depending on where you live in the world, humidity can cause your valves to seize. I was playing a gig in Washington, DC this summer with the US Army Band Pershing's Own and one of our horn players' rotors seized, and one of the trumpet player's valves seized too - being from Ottawa, Canada, the humidity in DC was a huge change! Also, if your top valve caps are too tight, it can cause the reaction of the valves to seem like they're locking. This happened to the 4th valve on my piccolo trumpet. Another issue to consider is the gap between your piston and the outer casing. The smaller the gap, you need an oil with less viscosity. The larger the gap, an oil with higher viscosity often works better. After owning a few different horns, I've learned which oils work better for each brand of trumpet. Just some food for thought!
Q:Is my Gas Valve faulty ?
I was wondering why the flue is clogged? I've never had to clean mine. Well anyway, I use a shop vac to vacuum out any dust or rust that accumulates on the gas valve on the rare occasions it failed to work,and that fixed it every time.
Q:How to adjust lawn mower valves?
I accept as true with Renpen (as commonplace) i'd prefer to furnish one extra factor I easily have seen ensue. I had an engine in my save for an intensive verify-up. I tuned it up, replaced oil and all filters, adjusted the valves and it ran nicely! It got here back in a week skipping. The valves have been out of adjustment back, so I reset them and it ran nicely back. back it got here the subsequent week with the comparable difficulty. long tale short (too previous due i understand) while the aluminum heads would get warm and enhance the stud would artwork it extremely is way out a pair of thousanths. the only scientific care became into to change the defective head.
Q:function of idle air control valve?
The IAC (Idle Air Control Valve) controls the amount of air getting into the throttle body/intake to coincide with the correct amount of fuel to get the perfect fuel/air mixture for proper combustion. Too much or too little air will affect the performance of the engine at idle. If you have the 5.7 350 v8 the idle air control valve is really an easy fix. it sits right in the throttle body and is easy to get to. Autozone in Houston, TX has them for about $22... If you don't get it your idle will be poor and the engine could possible stall at idle.
Q:Leeky Aortic Valve Questions?
Valvar insufficiency/regurgitation that is a result of surgical repair of a congenital defect does not self-resolve. It's not clear what your initial diagnosis was, however I would guess that you were born with aortic stenosis. Balloon enlargement and/or surgery to repair a stenotic valve almost always results in some degree of insufficiency/regurgitation. A small amount of insufficiency/regurgitation is much better tolerated than stenosis. It is a tradeoff we accept for improved patient outcomes. Really, the answer to your question is dependent on a multitude of factors, the most important of which is the degree of insufficiency/regurgitation you have (i.e. trivial, mild, moderate, or severe). This is really a great question and you deserve a full explanation. However, I cannot give you a factual answer without more information. You may also have a bicuspid aortic valve, which opens up a whole other set of variables. One thing I am sure of, however, is that you will require the care of a cardiologist for the rest of your life. It's possible that later on you may only have to follow-up ever 1-3 years, however, it will forever be necessary to properly monitor your valve and its effect on your heart, not to mention any associated problems you may not be aware of that become a risk with age. Good luck.
