ISO9001 Carbon Graphite Seal Ring Valve Seat And Rod Seal In Machinery Valve

Customized Carbon Graphite Valve Seat And Rod Seal In Machinery Valve

The sealing performance of the valve refers to the ability of the sealing parts of the valve to prevent the leakage of the medium. It is the most important part of the valve. There are three sealing parts of the valve: the contact between the sealing surface of the opening and closing parts and the valve seat; the joint of the packing with the valve stem and the stuffing box; the connection between the valve body and the valve cover. The leak in the former place is called endoleak, which is commonly referred to as the lack of tightness, which will affect the ability of the valve to cut off the medium. For shut-off valves, internal leakage is not allowed. The latter two leaks are called external leaks, ie the medium leaks from the valve to the outside of the valve. External leakage can cause material loss, pollute the environment, and cause accidents in severe cases. For flammable, explosive, toxic or radioactive media, external leakage is not allowed, so the valve must have a reliable sealing performance.

You can benefit from these advantages:

1. Resin impregnated material would be good porosity & high compressive strength
2. Its low cost but high quality compared raw graphite
3. High quality such as excellent self-lubricating, chemical resistance and

stable performance in a long service life
4. Customized is provided according to your drawings or sample

5. ZC carbon technology meets your special dimensional needs
