Description

16" Wafer Butterfly Valve — Replaceable Cartridge Seat Design



The 16-inch (DN400) wafer butterfly valve from Laux Valve features an innovative replaceable cartridge seat design. Unlike conventional lined or bonded seat valves, the cartridge seat can be replaced in the field without special tools, significantly reducing maintenance downtime and extending the valve's service life.



Key Features



    • Replaceable Cartridge Seat — Quick field replacement reduces downtime. No special tools required.

    • Wafer Type Design — Compact, lightweight, and cost-effective for installation between flanges.

    • Ductile Iron Body — ASTM A536 Grade 65-45-12 ductile iron for strength and durability.

    • Class 150 / PN16 — Rated for standard industrial pressure classes.

    • API 598 Tested — 100% hydrostatic shell and seat leakage testing.

    • Full Traceability — Each valve serial numbered with recorded test data.

Why Choose the Replaceable Seat Design?


Traditional butterfly valves require complete valve replacement or factory refurbishment when the seat wears out. The replaceable cartridge seat design allows:



In-situ seat replacement in minutes, not hours

No valve removal from the pipeline

Reduced spare parts inventory (stock seats, not complete valves)

Extended valve body life — the body outlasts multiple seat replacements

  Lower total cost of ownership over the valve's lifetime



Applications



Water treatment and distribution systems

HVAC and building services

Industrial process cooling

Irrigation and agricultural systems

Municipal water supply
