Design Features

1. With specialized surface hardening treatment, our products effectively overcome frequent wear‑out and replacement issues for metal‑hard‑seated ball valves under harsh service conditions.Our self‑developed ball valves feature low flow resistance, full‑bore passage, fast on‑off action and easy automation, which gain increasingly wide‑range applications worldwide.We are committed to delivering premium‑quality and efficient services tailored to your requirements.

该产品采用了特殊的表面硬化处理，彻底解决了金属硬密封球阀在恶劣工况下易磨损，频繁更换的难题。我们研制开发的金属硬密封球阀，具有流体阻力小，流道通畅，启闭迅速，易于自动化控制的特点，得到了越来越广泛的应用。公司将为您的要求提供优质和高效的服务。

2.According to customers’ different working‑condition requirements, our balls and seats can be processed with multiple advanced hardening technologies: supersonic spraying, nickel‑based overlay welding, customized surface hardening, hard‑alloy welding and high‑strength & high‑hardness ceramic materials.The surface hardness of ball and seat normally exceeds HRC60, and can reach HV1800‑2000 after our exclusive surface treatment. The sealing material withstands continuous temperature up to 540℃ with a maximum of 980℃, and its bonding strength is higher than 10,000 PSI. The sealing layer also possesses outstanding wear‑resistance and anti‑impact performance. Therefore our metal‑to‑metal ball valves are suitable for most severe working environments.

我们的金属硬密封球阀的球体与阀座针对用户的不同使用工况和要求，可以采用多种先进的硬化技术，包括超音速喷涂、镍基喷焊、表面特殊硬化、硬质合金喷焊以及采用高强度高硬度陶瓷材料等。球体和阀座的表面硬度一般可以达到 HRc60 以上，采用公司特殊表面处理，最高可达 HV1800‑2000。密封面材料耐温一般可达 540℃，最高可达 980℃。材料的结合强度可以达到 10000PSI 以上。密封面材料还具有很好的耐磨损、耐冲击等性能。能够适用于绝大多数的苛刻工况条件。
