2、 Detailed information
Product Overview
Orbital ball valve, which combines the main advantages of gate valve, globe valve, plug valve, and ball valve, has the characteristics of small opening and closing torque, long service life of sealing pairs, and forced sealing. The valve seat sealing form can be selected according to the working conditions and customer requirements, and is suitable for industrial fields such as petroleum, chemical, and metallurgical harsh working conditions.
Design and inspection can comply with standards such as API 6D, ASME B16.34, GB/T 19672, ASME B16.5, GB/T9112~9124, HG/T20592~20635, GB/T 12224, and API 6FA. Fire safety meets the requirements of API607/API 6FA and has been tested and certified. NACE anti-corrosion and acid resistance are optional.
