The ultra-high pressure needle valve is designed specifically for ultra-high pressure working conditions, with a compact structure and strong blast resistance.
The Y-shaped high-pressure needle valve adopts a Y-shaped flow channel structure, effectively reducing flow resistance and improving flow capacity
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
Adopting a 90 ° right angle flow channel design, it is suitable for pipeline systems with high pressure, high viscosity, or media containing micro particles. The conical needle valve core is matched with a hard alloy sealing surface to achieve precise flow regulation and tight shut-off.
The low-temperature and high-pressure welding needle valve adopts a fully welded valve body structure to eliminate the risk of external leakage
