Stem for ball, globe and gate valves', CNC machined, heat number marked
Stem is a important part of the valves, gate valves, globe valves, butterfly valves and ball valves all have the stem, the stem are the forging or bar material, so the strengthand toughness properties are very good.
The advantages as follows:
The dimensions is very accurate.we can guarantee the size error within 20micron for each body.
The surface finish is very good, because we machining the body used for CNC and drill holes used for machining center.
we can save more cost of materials because we have the forging company and CNC machining by ourself.
The forging or bar material are no cracks and packing with pearl wool to protect the surface.
