Other remarks 1

The extension dimensions of valve stem and bonnet may vary according to different temperature ratings.

Other remarks 2

As valves subject to a temperature ≤-101℃ shall be protected against subzero deformation, the main parts are subzero treated.

Other remarks 3

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 life of valve.

Other remarks 4

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

Other remarks 5

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

Other remarks 6

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

Other remarks 7

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

Other remarks 8

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

Other remarks 9

Small switching moment, reliable sealing

Other remarks 10

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 11

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

Other remarks 12

Y-shape stop valve – the streamline flow pass has a very high flow coefficient, and can maximally reduce the pressure drop through the system.

Other remarks 13

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.
