Product Overview
The metal-sealed carbon dioxide medium forged steel three-way ball valve is a special valve specially designed for carbon dioxide (CO₂) medium. It adopts a forged steel valve body, metal hard seal and three-way flow channel structure, which can reliably cope with the harsh working conditions of liquid, gaseous and supercritical CO₂, and achieve precise medium switching, distribution and isolation control.

Product features
1. Specialized metal sealing system
Super-hard sealing surface: The sealing surface of the ball and the valve seat is made of supersonic sprayed tungsten carbide or Stellite alloy, with a hardness of HRC≥58
Low-temperature adaptability: Special heat treatment process ensures that the sealing components do not become cold brittle at -196℃
Zero leakage design: Precisely ground metal sealing pairs achieve bubble-level sealing
2. Forged steel valve body structure
High strength characteristics: Forged into shape, optimized grain flow direction, tensile strength ≥485 MPa
Excellent compactness: No casting defects, and the pressure-bearing capacity is increased by 30%
Material traceability: Provide complete 3.1 material certification certificates
3. Special design for CO₂ medium
Preventing dry ice formation: The special valve cavity pressure relief design prevents the formation of dryness when liquid CO₂ vaporizes
Low-temperature treatment: All pressure-bearing components undergo deep cryogenic treatment to eliminate manufacturing stress
Sealing material optimization: Special composite materials are adopted in response to the permeability characteristics of CO₂
4. Three-way function configuration
L-shaped flow channel: It realizes the switching control of the medium between two outlets
T-channel: Completes the diversion, convergence or complete cut-off of the medium
Flexible switching: A single valve replaces multiple two-way valve combinations, simplifying pipeline design
