United Brass Works 363 Continuous Blow-Down Valve Overview
The United Brass Works 363 Continuous Blow-Down Needle Valve is designed for controlled boiler surface blowdown in steam and hot-water systems. This Class 300 globe-pattern valve uses threaded connections, a rising stem with swivel disc holder, and a calibrated flow indicator that helps operators make repeatable adjustments during continuous boiler blowdown.
The Model 363 is rated for up to 390 PSI at 500°F, with a maximum boiler blow-down pressure of 312 PSI. Its hardened stainless-steel seat and disc are designed for demanding boiler service, while the compact 1/2-inch and 3/4-inch configurations make it suitable for maintenance, replacement, and new boiler installations.
This valve is commonly used where operators need precise control of dissolved solids removal, boiler water quality, and continuous steam-system blowdown. Contact JJC Global Group for current availability, lead time, and quotation.
