4 inch ductile iron wafer butterfly valve with aluminum bronze disc gear operated EPDM finish

Legend Valve

Legend Valve 116-444 4" T-335AB-G Butterfly EPDM Valve

SKU CH-H4KR-J74XD

A 4-inch ductile iron wafer butterfly valve with aluminum bronze disc, gear operation and EPDM seat

  • 4-inch wafer butterfly valve fits standard flanges
  • Ductile iron body resists corrosion and pressure
  • Aluminum bronze disc handles abrasive fluids reliably
  • Gear operator enables precise flow control with low torque
  • EPDM seat suits water and glycol-based systems

4" T-335AB-G Butterfly Valve

The Legend Valve 116-444 is a ductile iron wafer butterfly valve designed for flow control in piping systems. It features an aluminum bronze disc and EPDM seat material suitable for compatible fluid applications. The gear operator provides mechanical advantage for opening and closing the valve. This component serves industrial and commercial plumbing installations.

Ductile Iron Wafer Body With Gear Operator

The wafer-style body fits between standard flanges for a compact installation profile. Ductile iron construction offers structural strength for demanding service conditions. The gear operator allows precise manual control without the effort of a bare shaft or lever. Aluminum bronze disc resists corrosion in many water and chemical environments.

EPDM Seat For Compatible Media Service

The EPDM seat provides sealing performance within its approved temperature and chemical range. Gear operation reduces the torque required at the handwheel during normal cycling. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm. Proper material verification against the specific service media remains essential.

Questions about this item

What pipe standard does the 4" T-335AB-G wafer butterfly valve fit between?

The wafer body is designed to fit between standard 4-inch flanges, so it matches the bolt-circle pattern of common 4" piping systems.

What clearance and hardware are needed to mount the gear-operated valve?

The ductile-iron wafer body sits between two flanges; you need two flange gaskets, a full bolt set, and enough pipe spread to slide the wafer in without forcing the EPDM liner.

Which step is most often missed when installing the gear-operated butterfly valve?

Installers frequently forget to centre the wafer with the flange bolts before tightening, which pinches the EPDM seat and makes the disc bind when the gear operator is turned.
