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 to replace an egr valve on a 2002 mercury sable?
Un plug the vacuum hose on top of the valve, loosen and remove the big tube nut on the bottom of the valve, I have found if you hit it sharply with a hammer 3 or 4 times before you try to loosen it won't break the valve off, once the tube nut is undone remove the 2 bolts holding the EGR valve to the intake manifold. Remove and discard the gasket and install the new valve in the reverse order. If the tube nut still won't come loose try heating it with a torch, if it's really rusted on you might have to replace the EGR tub along with the valve.
Q:does my 96 accord have an oriface valve?
It uses an expansion valve inside the evaporator assembly, part 11 in the first source. If the evaporator valve is not working the compressor will be damaged - by no oil if the valve stays closed or by slugs of liquid spilling out of the evaporator if it sticks open. Fortunately, orifices and expansion valves are very reliable. I bet a standard A/C service (about $100) will get you cool again. If you do anything to disturb the refrigerant loop (trying to charge it at home, trying to change refrigerant system parts) you will only spend more... probably a lot more.
Q:Chevy small block valve train ?
Only way to be sure is to put clay on top of a piston and turn the engine over by hand and then measure the clearance on the indentation in the clay.
Q:Diagnose extent of damage from stuck valves?
a valve stuck in the open position when cranked by a starter motor can put a hole in the piston it depends on which 460 7.5L you have some are flat top some are popups where centers are raised ive seen both in stock motors motorhead is right you can free them but you'll wanna soak them down constantly for a week or so remember they didnt get like that over night DO NOT crank over with starter use bolt on balancer as you'll feel resistance should you encounter a stuck open valve its so much easier with heads off but you can see the guides by removing valve covers if your valves are stuck your guide seal are junk trust me
Q:could i have a Bad EGR Valve?
you might want to check you egr lines. they may be blocked. not just the valve. also check your O2 sensors and make sure that they are operating properly.
Q:how to adjust a 2001 kawasaki zx9 ninja valve?
Intake and exhaust valves have different clearances.Which one?To check the clearance- the cam must be in the proper position.Then you take a feeler gauge and measure the distance-you have to do this to each valve before you can remove the cam to make an adjustment.Under the cam lobe-on top of the valve there is a can that rides up against the cam lobe.Between the inside of the can and the top of the valve there is a little round pocket that has a shim that looks like a watch battery.These shims come in different sizes--replacing them with a different size is how you make the adjustment.This is not anything that I would try to do without a manual--things can go bad real quick in the adjustment stage.Not a job for a 1'st timer but you can learn if you watch someone doing it.
Q:Two PVC valves?
No No No, The PVC valve removes a measured amount of crankcase blow by, oil vapor and water to be re-burned in the combustion chambers for emissions standards. The breather in the valve cover is needed to let atmospheric pressure in the crankcase to replace the air the PVC valve and hose has already been removed. I think you've been reading up on dry sump systems. Race engines make more power with a crankcase under vacuum while running.
Q:Leaking Proportioning Valve?
First up is that the valve is not leaking oil, it is leaking brake fluid. That is bad. The proportioning valve controls the brake pressure to the rear brakes. Most of the braking is done with the front brakes and without the valve you could lock up the rear brakes on medium to hard stops and the rear end could loose traction, that would be a bad thing on a sharp turn. With that said please replace the valve I have never seen a repair kit for them. Have you looked at to GM for the part? They may also have knowledge on a conversion of the master cylinder with the valve built in.
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:How to fix a trumpet valve?!!?
Your first step is to clean the valves and the casings. You'll need a casing brush or soft cloth you can run through the casing to clean them. Start with warm soapy water (dish washing soap) then clean them with alcohol--if you don't have alcohol use a water with a little vinegar added. You may need to let the valves soak a bit to loosen everything up. Remove the soap and alcohol from the casings and the tubing--rinse the valves and pat them dry. Inspect them for damage, if none is found then oil the valves and re-install them. If that doesn't work take it to a shop. Don't try lapping your valves yourself.
