1. Lug Body – Dead-End Service Capability
Threaded lug inserts allow direct bolting to a single flange.
Enables end-of-line installation without downstream flange support.
Ideal for isolation points, maintenance shut-offs, and future pipeline extensions.
2. CF8M Stainless Steel Disc – Superior Corrosion Resistance
CF8M (AISI 316) offers excellent pitting and crevice corrosion resistance.
Suitable for seawater, brine, treated water, and mild chemicals.
Provides long service life with minimal maintenance.
3. Replaceable Soft EPDM Seat – Easy Maintenance
The EPDM seat can be replaced in the field without removing the valve from the pipeline.
Reduces downtime and lowers long-term ownership costs.
EPDM offers excellent resistance to water, steam, ozone, and mild chemicals (-20°C to +120°C).
4. Reliable Sealing & Low Torque
Bubble-tight shut-off (Class VI) with resilient soft seat.
Low friction between polished disc and seat reduces operating torque.
Suitable for manual lever, gear, or automated actuation.
5. Compact, Space-Saving Design
Lug-style body fits between standard flanges (EN 1092, ANSI B16.5, etc.).
Lighter and more compact than full flanged valves.
Saves installation space and reduces structural support requirements.
