Schubert & Salzer – Type 7030 Flange Valve

Overview

The Schubert & Salzer Type 7030 is a pneumatically operated flange valve designed for on/off control of gases, vapors, and fluids in larger pipe sizes. Built with a ductile iron body (A395 Grade 60-40-18) in a take-out length and flange pattern per DIN EN 1092-1, the Type 7030 is available in 4″ and 6″ sizes and rated to 235 psi with media temperatures from 14°F to 338°F.

The Type 7030 is suited for industrial pipeline installations where flanged connections and a robust ductile iron body are required. Optional ATEX non-electrical approval is available for hazardous area use, and a pressure relief version is offered as an accessory configuration.

Features & Benefits
