Definition of Y-Type High-Pressure Needle Globe Valve

The Y-type high-pressure needle globe valve is suitable for high-temperature and high-pressure applications, enabling maximum flow rate and minimum leakage. It is available in cast (standard configuration) and forged (optional configuration) versions.

Structural Characteristics of Y-Type High-Pressure Needle Globe Valve

Adopts an optimized flow passage to minimize flow direction changes and reduce pressure drop.

Robust valve body design minimizes valve body deformation and leakage.

Split-type design minimizes valve body stress, thereby extending the service life of the valve body and weld overlay.

Provides precise disc alignment through the valve seat to minimize leakage between the disc and the valve seat.

Certified for fugitive emissions in accordance with ISO 158748-1, Class 2500 pressure rating, and CO3 durability class (2500 mechanical cycles).

Certified for fugitive emissions in accordance with API 624.
