Carbon steel globe valve is forced sealed valve, valve closure, must be applied to the disc pressure to force the sealing surface does not leak. When the medium enters the valve body from below the disc, the resistance to be overcome by the operation force is the friction force between the stem and the packing and the thrust force produced by the pressure of the medium, so the valve stem diameter to be large, the valve stem bending will occur.


Carbon steel is used in higher temperature, or concern with thermal or mechanical shock is an issue, which makes them popular in the oil and petrochemical industries.


Body and bonnets are high quality cast and afterwards precisely machined, directing the attention to prevent stress concentration.


Bonnets are made either of one piece only-the yoke then being an integral part of it-or have two pieces, depending on the size of the globe valve. This ensures the perfect alignment with the body what leads to an accurate opening and closing.


Bodies of globe valves are designed considering the same characteristics as gate valves, which in this case means that disc is guided in bigger valve sizes or high pressure service in order to avoid vibrations and better seat.


The design of the body-bonnet gasket varies depending on the class of the globe valve.

Class 150 to 600 globe valves consist of a circular male-female connection with a graphite or spiral wound gasket.


Class 900 and above globe valves consist of a ring type joint.

In pressure seal designs the sealing in achieved through a gasket that takes advantage of the internal pressure of the line. The material most commonly used is high-purity graphite being located between the body and the body retainer ring.


Design Features

Design standard as per: BS1873、GB/T 12235

Generally, lift is just 1/4 of the valve seat port, ensuring a short Opening/closing time. 
Only one sealing face exists on the valve body and disc.

The valve is designed as a back seat sealing structure.

Use flexible and woven graphite collaboration type packing.
