Overview

The ZQV Y-Type Globe Valve combines a rugged forged steel body with an inclined Y-pattern seat arrangement, delivering fine throttling control while keeping pressure loss low. The forged construction and compact bonnet suit high-pressure, small- to medium-bore service such as steam drains, bypass and chemical injection lines. A renewable hardfaced plug seats against a matching ring for repeatable regulation and tight shut-off, while threaded, socket-weld or flanged ends provide flexible installation across demanding process and utility systems.
