VAG LIMU‑STOP® Non-Return Valve

The VAG LIMU‑STOP® is a fully-flanged, resilient-seated non-return valve featuring a high-opening slanted seat and either internal or external shaft designs. Its compact design enables easy installation, cleaning, and maintenance. Built for optimal performance in water and wastewater systems, its large opening disk is piggable in the flow direction, making it highly cost-efficient.

– Drinking water, raw & cooling water
– Domestic sewage and wastewater
– Weak acids, alkaline solutions, and oil-containing media

– Internal Shaft: Sealed shaft within the body, ideal for compact, corrosion-sensitive environments.
– External Shaft with Lever & Weight: Includes a lever-weight mechanism for vertical alignment and easy swing function.
– External Shaft with Lever, Weight & Wire Guard: Adds a protective wire guard, hinged for 180° opening for maintenance.

– Body & Cover: Ductile iron EN‑GJS‑400‑15 (GGG‑40), factory-applied internal and external epoxy coating per GSK standards
– Disk & Seal: Stainless steel disk (grade 1.4308) with NBR seal; internal disk shaft steel grade 1.4057; bronze shaft bushing
– Anti-Corrosion Coating: Epoxy coating meets GSK quality benchmarks, designed for longevity in corrosive water environments

Works effectively with potable water, wastewater, and mixed industrial discharge media. The NBR seal ensures resistance to common contaminants and mild chemical exposure.
