High-Pressure Durability and Versatile Application

Designed for Class 4500 pressure ratings, this globe valve withstands severe industrial conditions. Its robust construction ensures a long service life in water, gas, oil, and steam systems across refineries, power plants, and pipelines. The anti-corrosive coating helps resist wear and extend operational longevity.


Precision Engineering for Reliable Operation

Equipped with a bolted bonnet and a rising stem (OS&Y design), the valve delivers precise flow control and straightforward manual operation. The handwheel and clear stem indicators aid operators in maintaining accurate valve positioning under demanding temperature and pressure environments.


Compliant and Safe Performance

Meeting rigorous industry standards such as API 602, ASME B16.34, and ANSI B16.104 leakage class, this valve guarantees reliable sealing with either metal-to-metal or soft seated design. Hydrostatic and pneumatic pressure testing ensures every unit delivers safe, leak-free operation under rated conditions.
