描述
BJ45H/W/Y 夹套保温截止阀
The BJ45H/W/Y jacketed insulated globe valve is designed for applications where
the process medium must be heated or kept warm during pipeline operation. The
jacketed construction helps reduce heat loss and supports stable flow of media
such as urea, nitric acid and acetic acid.
This valve is available in BJ45H, BJ45W and BJ45Y configurations, including
BJ45H-16C, BJ45W-16C and BJ45Y-16C. It is suitable for chemical, fertilizer,
petrochemical and other industrial process systems requiring reliable shut-off
and thermal insulation.
