SKU CH-ZBT3-ZMA2A

Eight-inch ductile iron wafer butterfly valve with aluminum bronze disc, Buna seat, and ten-position lever handle

  • 8-inch ductile iron wafer valve handles high-flow shut-off
  • Aluminium bronze disc resists corrosion in demanding fluids
  • Buna seat provides reliable sealing for water and oil
  • Ten-position lever handle gives precise flow control
  • California Proposition 65 warning flags chemical exposure risk

Valve Type and Application

The Legend Valve 116-427 is an 8-inch wafer-style butterfly valve designed for flow control in plumbing systems. It features a ductile iron body with an aluminum bronze disc and a Buna seat for sealing. The valve is operated by a 10-position lever handle for manual adjustment. It is intended for installers needing a quarter-turn shut-off or throttling device.

Disc and Seat Materials

The single specification that decides fit is the combination of an aluminum bronze disc and a Buna seat. These materials determine chemical compatibility and temperature limits for the specific fluid being handled. Buyers must verify that both the disc and seat are rated for their media before purchase. Systems requiring a different disc alloy or an EPDM or Viton seat cannot use this valve.

Proposition 65 Compliance Notice

This product carries a California Proposition 65 warning for exposure to chemicals known to cause cancer and birth defects or other reproductive harm. The notice applies to the valve as supplied and does not describe thermal, noise or power characteristics. No operational power draw, sound level or heat generation data is provided for this mechanical component. Installers should follow standard safety practices when handling and installing the valve.

Questions about this item

How does the 8-inch size translate when the valve is installed in a pipeline?

The 8-inch designation refers to the nominal pipe diameter, meaning the wafer body fits between flanges sized for 8-inch piping systems.

What does the 10-position lever handle actually control?

The lever handle provides 10 discrete notch settings, allowing incremental flow adjustment from fully closed to fully open.

What physical clearance is needed to mount the wafer body and operate the handle?

The wafer design sits between two flanges, so you need enough bolt-circle space for the 8-inch pattern plus swing radius for the lever handle.
