Y Pattern Globe Valve

The Y Pattern Globe Valves is only suitable for full opening and full closing, and no adjustment and throttling are allowed. The globe valve is a forced seal 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 under the valve, the resistance that the operating force needs to overcome is the friction force of the stem and the filler and the thrust of the pressure from the medium. The force of the valve is larger than that of the valve, so the diameter of the stem is large, otherwise the valve rod will have the failure of the top bending.

Product Features

This product has logical structure, reliable seal, excellent performance and nice design.
Sealing face is overlayed by STL, which is friction-resistant, corrosion resistant to ensure a long time use life.
Stem heat-treatment and surface nit riding-treatment to ensure function of corrosion resistance and friction resistance.
It has double seal, thus the capability is more reliable.
The stem may show the position of lift, thus it is more clearer.
The parts material, flange and butt welding dimension may selected according to current operating condition or users' requirement to meeting the requirement of various engineering.
