Overview

The graphite self sealing packing ring of the water pressure blocking valve | also known as the self tight sealing graphite packing ring at the outlet of the superheater. Made of pure flexible graphite paper, after cutting, the graphite paper is spiral wound and pressed into a circular graphite packing with a 45 degree angled mouth in a mold. It can be used for sealing the upper and lower end faces of the packing box or used as a separate set, especially suitable for sealing high-temperature and high-pressure parts, such as the 45 degree angled mouth self tightening gasket commonly used in power systems. According to customer requirements, $r $n can also have metal edging and corner wrapping on the upper and lower end faces.

Main technical parameters:

Temperature（Temperature）	--200～450℃ (non oxidizing)-200～800℃）
pressure(Pressure )	≤35MPa
PhValue（PH range)	0-14
Linear velocity（Linear speed )	10m/s

　Application:

Having various characteristics of expanded graphite, it can withstand intense temperature and pressure fluctuations, making it an ideal packing for valves and various static seals. Except for avoiding use when the valve stem is severely damaged, it can be used alone or in combination with JJ-771 high carbon fiber disc root end ring to prevent packing extrusion.
