Casting Steel Material
Visual check for cast steel material includes: surface quality, dimension, chemical properties, mechanical performance,
non-distructive testing to ensure that the comprehensive performance of raw materials
comply with the relevant ASTM, BS , EN , JIS standards.
The design provides the whole structure of low flow resistence channel structure,
enables the body stiffness and strenght to bear the nominal piping pressure and stress loading.,
the valve body wall thickness design complies with the API 600 with sufficient margin corrosion resistance for the medium.
Bonnet can be designed with a variety of seal structure of body connection to meet the needs of different operating conditions,
the structure can be equipped to connect with jacketed, flat, spiral or metal ring gasket,
and self pressure-seal valve bonnet for class 900/1500/2500.
Seat structure can b e designed as per user requirements as a whole alloy steel materials pressed-in sealing structure,welding sealing or screw connection in assembly. The austenitic stainless steel body material can be provided with integral seat.
The wedge structure design can be solid, flexible or parallel dual plates and has enough strenght and stiffness to ensure the valve sealing performance.
Seat and other materials
The choice of materials for the seat and other seal material can be as per API 600 stadards or users design and manufacturing requirements.

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.
