Product Description:

Design Features of full welded forged steel ball valve

The body of ball valve is full welded,selects high quality forged material,and adopts the advanced forged forming technology to form two semi-spheres which are welded into a whole in the middle of the body.This welding technology differentiates the ball valve form others,and makes the valve more spherically,so the valve structure is more compacter,lighter and stronger.Besides,the middle direct welding realize highly accurate valve body manufacturing,makes fully and completely sealing between the seat and ball.The full welding instead of bolts completely avoids the outside leakage,so ball valve is the ideal product for under-ground,offshore working platform and under-sea equipments.

Adopting fixed plates or trunnion to support the ball

The top and bottom of the ball is supported by upper and lower fixed plates or stem and trunnion,and the ball is accurately placed in the center of the ball valve to achieve complete seals and precise movements.When plate adopted,the force exerted by the medium to the ball is distributed via the plate to the left and right bodies,so that the stem does not bear the blending moment from the medium,but only the torque from the ball rotation during the opening/closing of the valve.The low-friction PTFE Teflon composite bearings installed between the ball axis and fixed plate and between the stem and the trunnion can absorb ball moving action caused by the pressure of the medium.This structure brings stable actions and easy operations for the ball valves,and the required operation torque can be reduced,so smaller actuators can be used,and the cost is cut down.

ball valve seat is floating structure,means the seat can move along the medium direction,so that the seat can fit against the ball all the time.
Double piston effect structure seat of full welded forged steel ball valve
Seat design is special double pistons effect structure,it can ensure the seal wherever the medium flows into the ball valve.

Seat multistage seal strucute of full welded forged steel ball valve
As following graphic instruction,on seat bearing ring,set two soft sealing rings(A and B)and metal sealing spherical surface which can seal with the ball.Seat ring A is spring loaded,which seals the surface with the ball tightly to the surface to form an initial seat;When there is pressure generated from medium,the piston force is generated to make seal ring A elastically deformed and seal ring B fit the surface of the ball surface due to the piston effect caused by area difference,thus the second seal forms.When the medium pressure is rising.It will generate huge pressure to seal ring A and seal ring B,so the two seals have a greater elastic deformation,then metal seal ball surface compact with ball surface to form the third level of metal to metal seal.

Secondary seat seal device of full welded forged steel ball valve
As the above graphic instruction,the secondary seal device(seat grease injection valve)can be chosen according to the actual working condition,medium requirement,seal requirement,etc.Seat ring grease injection valve is a one-way valve,installed on the body,which can prevent the leakage and inject grease under the outside force.When secondary seal is required,there is a grease injecting channel and hole on the seat ring.The grease can form a seal between the seat and the ball,and then stop the leakage.

Q:92 F150 Fuel tank selector valve?
There is no selector valve on 1992-95 F150's. There were or the older carbureted trucks but newer ones are all fuel injected and have in-tank fuel pumps. The switch on the dash just selects which pump you turn on. I'd say the front tank fuel pump has gone bad or possibly has a cheaper electrical problem (if you're lucky). Exact same thing happened to my 1995 F150. Replacing a pump is a pain and not cheap.
Q:How to adjust valves on Caterpillar C15 on-highway engine?
Ive gone 100s of these but that was 6 years ago. I do know you will need a special socket to spin the engine over till the bolt drops in the hole on the flywheel. and allen wrenches, feeler gauges, and deep offset boxed in wrenches, and a torque wrench for putting the exhaust brakes back on. Its pretty easy and only takes an hour or so. You will not need any gaskets, they are reusable rubber. The Main thing is to only adjust them when the engine is cold, you wont get the right lash on the valves if not. they might be to tight or loose, if the engine is not cool.
Q:vw aircooled valve seat?
It depends damage. The early duel ports also cracked because the mettle used was not good. A new one is not to hard to find or to expensive.
Q:HELP!!! trumpet valve stuck?
You could just get a screwdriver and drill it into the bottom of the valve till it comes out. Its not damaging anything because there are no air pipes going through the bottom .
Q:What causes burnt valves?
I was told that burned valves resulted from a poor machining job. By the way, I also have a Toyota. Hmmmmm. The car had all the valves replaced and the head gasket as well with only 12,000 miles on it.
Q:aortic valve stenosis severe amemia hemoglobin 9.1 ?
I don't know of there being any relationship. The only thing would be if your aortic valve was damaging your blood cells, but I don't think that is the cause of your anemia. I wouldn't call 9.1 Severe. It would have to be below 8 before anyone should consider giving you blood. I work as a nurse in a hospital and have seen tons of Hemoglobin levels in the 7's and 8's. I've seen a few 5 and 6's. So don't get too worried about how low it is, just keep looking for the cause and treat it that way.
Q:Blow off valve v. ByPass Valve?
Its a Cavalier guy, purely a complex new call with greater potential. Do because of fact the others say.. get a automobile with a constrained slip, something which could preserve fairly of torque, and save your self alot of headache (and it will nevertheless have some resale) interior the top... its no longer as great as they declare it to be... Chevys havent replaced lots over the years.. they have been acceptable with their slogan. Like a rock.. sink in basic terms as rapid.
Q:Toilet shutoff (stop) valve problem?
I think its the float in your toilet try pushing down in to the water and see if the flow begins again. If it does just readjust your float setting to the tank fill level you want
Q:ac replacement valve?
The valve itself is only a couple dollars. Some shops have a tool that will let them replace a valve without dumping the charge but since its likely low you will likely also have to pay the regular AC service fee which is usually $50-100 plus parts and refrigerant.
Q:two way one way valve?
Position two backflow preventers in oposite directions on your supply and exhaust line. connect them to a Tee fitting. the third end of the tee is where you will breathe
