Product Details
The nano high-silicon molybdenum alloy ball valve is a high-performance valve made of special alloy materials, and it is mainly used in fluid control systems under extreme conditions. The following are its core features and technical parameters:
Material Characteristics
Alloy Composition: The valve body is made of nano-scale high-silicon molybdenum alloy (such as silicon-molybdenum alloy with a molybdenum content of ≥15%), which is formed through powder metallurgy or directional solidification technology. It possesses both high hardness (HRC 55-65) and high-temperature resistance (with an applicable temperature range up to 800℃).
Surface treatment: The surface of the sphere is coated with tungsten carbide by supersonic spraying or plasma cladding of hard alloy, with a roughness of ≤ 0.4 μm. This significantly enhances the wear resistance and erosion resistance.
Structural Design
Sealing Form: Metal hard sealing structure. The valve seat adopts an elastic loading design. The sealing surfaces are ensured to be in close contact through the pre-tightening force of the spring, with the leakage level reaching ANSI Class IV-V grade.
Drive mode: Supports various driving methods such as pneumatic and electric. For the DN50 specification pneumatic actuator, the working air pressure is 0.4 - 0.7 MPa, and the opening and closing torque is ≤ 120 N·m.
Application scenario
Extreme operating conditions: Suitable for gasification plants, polysilicon production, etc., for media containing hard particles (such as silicon powder, coal ash), with a pressure resistance range up to PN64 (approximately 6.4 MPa)
High-temperature environment: Maintains stable performance even at temperatures above 650℃, with a low thermal expansion coefficient (≤ 1.2 × 10⁻⁶/℃)
Nanometer high-silicon molybdenum alloy ball valves are mainly applied in the following fields:
Chemical industry
Suitable for pipeline transportation and equipment connection of corrosive media such as sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, acetic acid, sodium sulfite, caustic soda, etc. Especially suitable for chemical wastewater treatment and seawater desalination treatment scenarios.
Electricity and Energy
Replace traditional materials in equipment such as acid production lines, concentration towers, bleaching towers, and condensers, reducing operating costs and enhancing corrosion resistance.
Notes:
Medium Restrictions: Prohibited for use with hydrofluoric acid (HF) and concentrated hydrochloric acid with a concentration higher than 50%;
Temperature Restrictions: The operating temperature should not exceed 150℃;
Transportation and Installation: During transportation and installation, avoid severe impacts.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
