DeltaGuard® GV850 — Isolation Valve




The DeltaGuard® GV850 Isolation Valve is a reliable, low maintenance, tight shut-off isolation valve designed for high temperatures / harsh applications. The throttling version is capable of operation continuously in the partially open or throttled position while isolating the body internals from the process. Steam purge requirements for the GV850 are extremely low. The GV850 design provides for practical and efficient in-line maintenance of all internal components without removing the valve body from the line.
