WCB slurry valve with wear-resistant armor and environmental protection via sodium silicate sand casting for high dimensional stability

In the harsh industrial fields such as mines, cement and sewage treatment, the slurry valve must not only face the test of high pressure, but also resist the severe erosion and wear of solid particles at all times. How to achieve green and precise manufacturing while ensuring extreme wear resistance?

We bring you the answer-WCB carbon steel slurry valve casting with advanced sodium silicate sand casting process, casting industrial hard core with green technology, and injecting endless green power into modern fluid control.

As the core of the slurry valve, the material determines its life. We select WCB carbon steel (weldable cast steel grade B) according to ASTM A216 standard, which achieves a perfect balance between strength, toughness and weldability. After strict normalizing heat treatment, WCB castings have formed a uniform pearlite+ferrite structure with excellent tensile strength (≥485MPa) and excellent impact toughness. Facing the slurry medium containing solid particles, it can show iron-like will, effectively resist erosion and wear, and is not easy to deform or brittle crack under the working conditions of frequent start-stop and pressure fluctuation, thus ensuring the long-term and stable operation of the valve.

Good materials need better craftsmanship. We fully adopt advanced sodium silicate sand (organic ester hardening) casting process. Compared with the traditional technology, sodium silicate sand is not only tasteless and nontoxic, but also greatly improves the working environment in the workshop, and has extremely high dimensional stability and surface smoothness. This precise molding technology ensures the smoothness of the internal flow channel of the slurry valve casting, greatly reduces the fluid resistance, and effectively prevents the medium from staying and scaling. At the same time, the used sand can be recycled by 100% thermal method, and the green manufacturing from the source to the terminal is truly achieved, so that your equipment not only has excellent performance, but also meets the high environmental protection standards of modern industry.

Relying on the excellent hard permeability and collapsibility of sodium silicate sand process, our WCB slurry valve castings show outstanding performance in the molding of complex structures. Dense and defect-free casting quality can be achieved whether it is the special-shaped flow channel inside the valve body or the flange joint with thick and large cross section. Combined with the excellent welding and machining performance of WCB material, we can carry out high-precision post-processing and customization of castings according to the special working conditions of customers, so as to ensure that each slurry valve can fit perfectly and truly "control the slurry and be unimpeded".

From the transportation pipeline of mine tailings to the control of raw slurry in cement plant; From sludge discharge from sewage treatment plant to slurry circulation in desulfurization system of power plant. Our water glass sand process WCB slurry valve casting is widely used in various severe slurry conveying systems with its excellent wear resistance, environmentally-friendly manufacturing process and high cost performance, and has become the preferred fluid control core for many heavy-duty projects.

A good valve comes from a good casting, and a green process casts the future. Choosing our sodium silicate sand process WCB slurry valve casting is a choice of wear resistance, environmental protection and peace of mind. Let us control industrial slurry with green technology and hard core quality, and protect the smoothness and safety of each fluid!
