Concept and characteristics of the stem

The valve stem is an important part for the transmission,on the next actuator or handle,

the following direct drive spool to move or rotate to achieve valve swich or regulation.

Stem in the valve opening and closing process is not noly moving parts,mechnaical 

parts,and the seal member.

So the choice of the stem material,it must ensure that the required temperature has 

sufficient strength,good toughness,scratch resisitance,corrosion resistance.

And our company adopts advanced CNC equipment.

More accurate

Brighter surface

Higher working efficiency

Stem is wearing parts should also note that in the selection of the mechanical prperties 

and heat treatment processing performance.
