The low temperature ball valve with overhaul adopts the top mounted structure, which can realize online maintenance. It is easy to disassemble and repair on the pipeline. When the valve fails on the pipeline and needs to be repaired, it is not necessary to disassemble the valve from the pipeline, just remove the bonnet bolts and nuts, remove the bonnet and valve stem assembly from the valve body together, and then take out the ball and valve seat assembly to repair the ball and valve seat online, saving maintenance time.

The low temperature maintenance butterfly valve is a three eccentric sealing butterfly valve. Its sealing surface is conical type, with an angular eccentricity in the horizontal center. The valve stem has two eccentric distances in the axial and radial directions relative to the center of the flow channel. The sealing pair is an independent and removable structure. The deformation under low temperature conditions is approximately the same, ensuring good sealing, and realizing rapid replacement and maintenance of internal parts.

Gate valve is a gate with opening and closing parts. The movement direction of the gate is perpendicular to the direction of the fluid. Gate valve is sealed by contact between seat and gate plate. Usually, metal materials are surfacing to increase wear resistance, such as surfacing 1Cr13, STL6, etc.

The globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve by the valve disc lower part...
