Other remarks 1

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.

Other remarks 2

The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.

Other remarks 3

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

Other remarks 4

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

Other remarks 5

Small switching moment, reliable sealing

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

Small flow resistance, high flow capacity and good flow characteristics

Other remarks 8

For small gate valves, the interchangeability can be ensured with process tooling.

Other remarks 9

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.

Design of Disc

Gate valves with NPS>=2 are flexible gate,gate valves with with NPS<2 are of solid gate.

If being requested by the customer,the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.
