The 25-100kg automatic fire extinguisher valve features a smooth, glossy coating that not only improves the valve's appearance but also effectively isolates the metal from the air, preventing rust and corrosion and extending the valve's service life.
Furthermore, the coating enhances the valve's wear resistance, reducing damage from friction and thus improving its reliability and stability. Moreover, the chrome or nickel plating is easy to clean, helping to maintain valve hygiene and prevent the accumulation of dirt and bacteria.
This valve maintains good performance in various environments, including humid and high-temperature environments. Additionally, we can customize chrome or nickel plating coatings according to customer requirements to meet diverse needs.
