General Globe Valve (Double Disc)

The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.…

Features & Benefits

During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height 

is relatively small. The action is sensitive and the sealing performance is good; the opening is quickly closed, and the torque is light. The overall 

structure, simple and compact, beautiful shape. Long service life and high reliability.


General Information

Design Standard: BS1873, API623, ASME B16.34

Main Material: Carbon Steel, Stainless Steel, Alloy Steel, Etc.

Size Range: NPS4~NPS20/DN100~DN500

Pressure Level: Class150~ Class 2500/PN20~PN420

Temperature Range: -29℃~540℃

Application Scenario: The globe valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require 

closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the 

application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry 

and other fields.
