Features and benefits

● Universal trim: 13Cr stem, wedge in CA 15 or 13Cr faced, and CoCr alloy seat API Trim 8 suitable for applications up to 850°F (454°C).
● Seat face CoCr alloy hardfaced, ground and lapped to a mirror finish.
● Flexible wedge with low center stem wedge contact, in solid CA15 (13Cr)or hardfaced with 13Cr, SS 316, Monel or CoCr alloy. Wedge is ground and lapped to a mirror finish and tightly guided to prevent dragging and seat damage. A CoCr alloy hardfaced CF8M wedge is also available.
● Non-rotating stem with precision Acme threads and burnished finish. Double Acme for faster operation.
● Body and bonnet joint accurately machined.
● Body and bonnet castings are precision machined. One-piece bonnet up to NPS 12 (DN 300) for better alignment and fewer parts.

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 life of valve.
Other remarks 2 SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing
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 The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.
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 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.
