In the petrochemical industry, valves are used to control fluid flow, pressure, and prevent accidents. They are capable of enduring high temperatures and pressures in refinery environments, ensuring safe and smooth operation of processes.
TIANYU DN15~DN2000 PN16 PN25 fully welded trunnion ball valve complies with API 6D, API 607 and CE PED standards, forged from ASTM A105 steel with nickel coated F316 trim and dual layer fire-safe composite seal. Its integrated monoblock welded body removes bolt joint leakage risks ideal for buried pipelines, dual trunnion design prevents large-diameter ball deflection while full bore channel cuts transmission energy loss. Featuring anti-corrosion buried coating and minimal maintenance demand, it delivers over 15 years stable zero-leak service for cross-country gas, crude oil and municipal large flow industrial pipelines with remarkable long-term economic benefits.
