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: I have a 1997 Toyota Corolla. My check engine light has been on. I tried to get my car smogged and it failed. I then got an oil/air filter change and just yesterday I replaced the EGR valve which was the result given after 2 diagnostic tests. The mechanic gave me my car and the check engine light was off, I've only driven about 5miles and the light is back on. I have to pass smog asap to register my vehicle. I plan on calling the mechanic back and telling him the light is on, but could it just be a sensor?
- it could be a sensor ! the EGR code probably showed up because a sensor was interfering with the valve !
- Q: It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?
- RET68 I think has the answer,the water heater Relief valve is a 150 lb valve,what you have is thermo expansion.It usually is noticed when a new water heater is installed,because the old water heaters relief valve was grimmy and corroded and wouldn't work anyway.some city water systems have a back flow preventer on the line where water enters the house this is a large problem contributing to the thermo expansion (when the water heats up it has nowhere to go besides out the pressure relief valve on your water heater).Private water systems don't have this problem because they have a pressure tank (well extrol) for there water.which is in essence a thermo expansion tank.
- Q: Can someone please help me on this anatomy question:Describe the physical similarities and differences in the structure of the AV valves and the semilunar valves.Thanks
- av valves are anchored to the wall of the ventricle by chordae tendinae, multicusped valves while semilunar valves do not have chordae tendinae, but are more similar to valves in veins. positioned on the pulmonary artery and the aorta both have the same function of prevent backflow of blood
- Q: I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
- valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
- Q: I have a 78 honda hawkii 400 or cb400TII and I need to know what the valve gaping needs to be set to
- Try okorder or usually free down loads.
- Q: What would be the effect on valve opening if the clearance was set too large or too small, please help
- Too Much Valve Clearance
- Q: Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
- vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
- Q: Can anyone tell me what is the industrial application for globe valve?? Please help. I tried to search in the Net but couldn't get.
- Application Of Globe Valve
- Q: How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.
- the heater control valve is in the heater hose under the hood. on the passenger side of the car there will be two heater hoses going into the engine wall. one of them will have a heater valve in the line with a cable attached to it. drain the coolant from the radiator before removing the heater hose or you'll get coolant all over the place and coolant is toxic to animals. after you drain the coolant you can remove the clamps that secure the hose to the valve. have a drain pan under the car as some coolant will still be in the lines. once you remove both clamps you can take the hoses off the valve then disconnect the heater cable. install the cable on the new valve and install in the reverse order. fill the radiator back up will the removed coolant. you'll need to run the engine until the thermostat opens and the coolant level in the radiator drops. then top off the coolant and put the radiator cap on. hope that that helps
- Q: as we are strating centrifugal pump with discharge valve close and can not start positive displacement comp. with disch. valve closed
- I assume you are asking about a centrifugal compressor being driven by a gas turbine. You didn't state the service the compressor was in but it is possible in some services for the centrifugal compressor to add a load to the gas turbine's output shaft during the starting cycle. By having the valves closed, there is only the load from compressor wheels) and shaft being accelerated to operating speed. This would permit the gas turbine controls more lee way to get the turbine speed under control before adding significant load to the output shaft. Another consideration is the need to load the compressor in a manner that would get it past the surge point and into a stable operating regime. This can best be done with the compressor at operating speed and a fairly quick addition of load.
