Parallel High Temperature Double Gate Valve

Brief Introduction:

Parallel high temperature double gate valves are mainly used in ethylene plant, ethane ethylene plant, propane dehydrogenation to propylene plant, MTO plant, butadiene plant and other petrochemical plants to cut off the flow of media.

he sealing surface has been relieved and the wear of the sealing surface is small when the valve is opened.

Double-sided hard seal and steam-assisted seal make the seal reliable.

The two valve plates are relatively independent to compensate for manufacturing errors.

Non-self-locking design, small opening moment.

Square flange uses lip seal to avoid leakage of medium.

The valve stem adopts double packing structure in series, and the sealing is reliable.

The valve body has only one disassembly port and leakage points is few.

Set valve position feedback and body cavity pressure feedback.
