Sedelon Pressure Seal Bonnet Gate Valve



High pressure valves generally will adopt pressure seal bonnet to have better sealing performance.


In terms of working performance,if the pressure is higher, the sealing performance will be better. 
But the pressure should be in the working pressure range.


The operating principle of the pressure seal bonnet valve is mainly because of the sealing function
of the sealing surface of the wedge.So that is why the pressure is greater, then the sealing is much
tighter. The connection between body/bonnet is pressure seal type, no leakage on this position


This pressure should be within the bearing range of the sealing elements .The self-sealing structure
is widely used in the upper sealing of the valve, which is mainly used in the operating conditions
above 900LB.
