carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3、Small opening pressure, the disc can be opened fully with a very small pressure differential.
4、Inside-set bolt-bearing structure reduces leakage and reliable use.
5、PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along
with the pressure rise so as to ensure the sealing performance.

- Q:I have a 04 Ford Ranger 4.0L . some people are saying that headers may affect the EGR valves and might put up the check engine light on. is this true or not.
- It depends on the headers. Some headers are setup with EGR hookups and others do away with them. So you need to check to see if the ones you are looking at retain the EGR and if they do you should have no problems. Also you might have to check the bolts weekly, some headers will get lose over time while others don't.
- Q:How hard would it be to fix an EGR valve on a 1990 Geo Storm that is stuck open? if not fixable, how much would it cost to replace it, or have it replaced by a professional?
- First, okorder /... I see that Autozone doesn't have that part, but it does mention there are 3 different possible part #'s, depending if it's a 2+2 or GSI, and/or Transmission type, so keep that in mind if you need to order a new one. Click EGR Valve in buy it here box for more info.
- Q:I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- take the bolts off pull off old cover and do the same with new cover!
- Q:I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?
- Maybe but usually MVP doesnt give people much problems and if it does usually sudden
- Q:I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.
- see if there is a slight protrusion on the valve. probably on a piece of plastic near or above the spring of the valve? that should fit in a notch in the trumpet valve tube. Just insert your valve partly in until the protrusion is resting on a ledge-like part. Then turn your valve around the tube gently until you hear a click when the notch goes in. You are right, the number on the valve usually faces the side where the mouthpiece is. Make sure your other valves are also placed in there correctly. If all else fails, ask the person who's teaching or taught you to play trumpet. or go to a trumpet store. Enjoy practicing!
- Q:does it moves up and down with the valve stem??
- A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve.. not sure if you are talking about tire valve stems? if so the poppet valve moves within the valve stem. I have also heard them referred to as Schrader valves see link
