GEMÜ R677

The GEMÜ R677 2/2-way manually operated plastic diaphragm valve provides universal flow isolation using a flow optimised straight through body. The GEMÜ R677 accommodates nominal sizes from DN 15 to DN 100, regulates operating pressures up to 10 bar, and withstands media temperatures ranging from -10°C to 80°C. Key Performance Capabilities: High Flow Structural Efficiency: The GEMÜ R677 integrates a flow-optimised high flow valve body, maximising media throughput within compact system layouts to reduce installation footprint and lower structural costs for plant engineers. Visual & Operational Verification: The GEMÜ R677 features an integral optical position indicator alongside optional position feedback, allowing operators to verify manual flow status instantly and prevent costly unplanned process interruptions. Lockable Actuation Security: The GEMÜ R677 offers an optionally lockable handwheel mechanism, securing mechanical flow regulation to eliminate accidental valve operation and protect critical pipelines during complex maintenance interventions. Safety & Compliance: Drinking Water & Food Conformity: The GEMÜ R677 holds FDA conformity and System 1+ drinking water hygiene suitability, ensuring safe integration into sanitary fluid networks and commercial potable water processing facilities. International Safety Standards: The GEMÜ R677 complies with ACS and EAC certifications, guaranteeing the diaphragm valve meets strict technical safety regulations for global industrial and municipal operations. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific body material (PVC-U, ABS, PP, PVDF) and diaphragm configuration selected for the GEMÜ R677.
