Four inch ductile iron wafer butterfly valve with aluminum bronze disc and ten position lever handle

Legend Valve

Legend Valve 116-404 4" T-335AB Butterfly Valve EPDM

SKU CH-GV1J-NA8W2

A 4-inch ductile-iron wafer butterfly valve with aluminium-bronze disc, EPDM seat and 10-position lever handle for flow control

  • 4-inch ductile iron body fits standard wafer installations
  • Aluminum bronze disc resists corrosion in water service
  • EPDM seat handles hot and cold potable water
  • Ten-position lever handle allows precise flow control
  • California Proposition 65 warning lists cancer and reproductive risks

4" Ductile Iron Wafer Butterfly Valve

This 4" T-335AB ductile iron wafer butterfly valve is designed for flow control in commercial and industrial piping systems. It features an aluminum bronze disc and EPDM seat material suitable for water and compatible fluid applications. The 10-position lever handle provides discrete throttling control for system balancing.

Thermals Noise and Power Draw

As a manually operated mechanical valve, this product generates no operational noise and draws no electrical power during normal use. Thermal performance is governed entirely by the temperature of the media flowing through the pipeline rather than the valve itself. The ductile iron body and EPDM seat maintain sealing integrity across standard service temperature ranges.

Replaces and Upgrades

This valve replaces worn or leaking wafer-style butterfly valves in existing 4" flanged piping installations where EPDM seat compatibility is required. The upgrade is worthwhile when the current valve disc material is incompatible with the service media or when the handle mechanism has failed. It is not suited for applications requiring automated actuation or ANSI class ratings beyond the wafer design.

Questions about this item

How is the 4" T-335AB wafer butterfly valve installed between flanges, and what step is often missed?

Center the valve between flanges, insert bolts through the wafer lugs, and tighten in a star pattern; the step often missed is verifying disc clearance before final torque.

What maintenance will the EPDM seat and 10-position lever handle need over time?

Inspect the EPDM seat for cracking or compression set annually; lubricate the lever handle pivot and check the 10-position notch engagement for wear.

What limit appears first when the ductile iron body and aluminum bronze disc operate continuously?

The EPDM seat reaches its temperature limit before the ductile iron body or aluminum bronze disc show stress under sustained cycling.
