Schubert & Salzer – Type 7342 Low Flow Valve – Electric Actuator

Overview

The Schubert & Salzer Type 7342 is a high-accuracy electric low flow valve designed for on/off and modulating control of liquids and gases at high pressures and very low flow rates. Available in 1/4″ and 1/2″ sizes in stainless steel 316L and rated to PN 320, the Type 7342 features a 2 kN thrust actuator — the highest thrust in the electric low flow valve family — and is rated IP67 for demanding environments. Media temperatures range from -76°F to +410°F with application capability from -76°F to +986°F.

Connection options include pipe thread per ISO 228-1, NPT per ANSI B1.20.1, and socket weld. The actuator supports control and 3-point configurations with 3-point, 2–10V, and 4–20mA control signals and a wide voltage range of 100–240V (50/60 Hz) or 24V AC/DC. A metal bellows option, analog stroke feedback, and fail-safe feature are available as accessories for zero-emission and critical process applications.
