Product Overview
The GEMU 673 is a pneumatically actuated diaphragm valve engineered for precise, contamination-free control of neutral, aggressive, and high-purity media in industrial process systems. Manufactured by GEMÜ (Gebrüder Müller Apparatebau), a global leader in fluid handling technology, this valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the working fluid from the actuator and eliminating dead legs, crevices, and seal leakage paths. The GEMU 673 is a direct-acting, normally closed (NC) or normally open (NO) valve with a compact plastic or metal actuator housing, designed for on/off and modulating duty in demanding process environments. Its hermetic separation between media and mechanism makes it ideal for sterile, corrosive, and abrasive applications where cross-contamination and maintenance downtime must be minimized.

Engineering Features & Advantages
- Precision Performance: The diaphragm design provides bubble-tight shutoff and precise flow control with minimal pressure loss, ensuring accurate metering of process media without cavitation or water hammer.
- Hermetic Media Isolation: The diaphragm completely separates the working fluid from the actuator and environment, preventing cross-contamination and enabling use in sterile and high-purity applications.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original GEMU OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
Typical Industrial Applications
Its hermetic separation between media and mechanism makes it ideal for sterile, corrosive, and abrasive applications where cross-contamination and maintenance downtime must be minimized.
