CO2 Valve

Model: Tr21*4

  • 1. Specialized compatibility, installation matches perfectly Designed specifically for carbonated water machines and soda water machines, with standard inlet M18×1.5 and outlet Tr21×4 threads. It perfectly matches the interface with the gas cylinder and the machine body, no need for modification, direct assembly, and highly versatile.
  • 2. Ultra-high pressure safety protection, more reliable explosion-proof Built-in 250bar high-pressure bursting disc, precise pressure relief in case of overpressure, preventing the gas cylinder or machine body from bursting. From the structural perspective, it eliminates potential safety hazards and complies with food and beverage equipment safety standards.
  • 3. Excellent sealing performance, no leakage or pressure loss Precise processing + high-quality sealing structure, no leakage or slow pressure loss during long-term use, ensuring stable gas production for the carbonated water machine and enhancing the overall user experience.
  • 4. Stable pressure-bearing, long service life High strength of the valve body, resistant to fatigue, and able to withstand repeated inflation impacts. It maintains stable performance even under frequent opening and closing, pressure fluctuations, reducing maintenance costs.
  • 5. Food-grade safety, compatible with beverage equipment The overall structure is clean and odorless, the materials are safe and compliant, suitable for food-grade scenarios such as drinking water, carbonated water, and soda water, with no secondary pollution.
  • 6. Customizable, compatible with multiple types of machines Can adjust the thread specifications, bursting pressure, valve body size, and interface structure as needed, compatible with household/industrial carbonated water machines, soda water machines, and air gun equipment, providing one-stop support.
  • 7. Compact structure, friendly installation space Small in size, simple in structure, does not occupy installation space, compatible with various integrated carbonated water machine structures, simple assembly and easy maintenance.
