Other remarks 1

The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service valve life

Other remarks 2

The friction between sealing faces is smaller during opening and closing, facilitating a longer service life.

Other remarks 3

The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate.

Other remarks 4

SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing

Other remarks 5

Rising stem structure, making the valve switch position be clear at a glance

Other remarks 6

The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.

Other remarks 7

A certain clearance is provided between valve clack and valve stem. You may adjust it by yourself. The sealing is reliable.

Other remarks 8

The valve clack can be machined into parabola, spherical, needle shapes, etc. according to the requirement of customer. It can be used for adjustment (rough adjustment) on pipeline.

Other remarks 9

Short stroke is suitable for application at positions subject to frequent opening.

Other remarks 10

Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.

The body and bonnet of class 150~Class 900 globe valves are usually with studs and nuts,body and bonnet of class 1500~2500Lb are usually with pressure seal design.
