Bellows globe valve belongs to the mandatory sealing valve, the opening and closing parts are plug-shaped valve flap, the sealing surface is flat or conical, the valve flap along the center line of the valve seat in a straight line; disconnecting valve valve stem opening or closing stroke is relatively short, and has a cut-off action, which makes it suitable for use as a medium of cut-off or regulation and throttling, suitable for steam, thermal oil and other media on the pipeline.

Bellows globe valve its key components metal bellows, the lower end and stem assembly with automatic roll welding welding, the upper end and connecting plate automatic roll welding, in the fluid medium and the atmosphere between the formation of a metal barrier, so that the valve stem no leakage, valve flap with a conical design, the sealing surface and the media into a streamlined, good sealing performance, long use.

Double sealing design (bellows + packing) if bellows failure, stem packing will also avoid leakage and meet the sealing standards, the bonnet comes with a grease filling connector, you can directly lubricate the valve stem, nut and sleeve, unlike the traditional only add lubricant to the threads, the handwheel, the use of a long time, easy to operate.
