  • Ten-position lever allows precise flow control
  • California Proposition 65 warning for chemical awareness

10-inch ductile iron wafer butterfly valve

This 10-inch wafer butterfly valve uses a ductile iron body with an aluminum bronze disc and Buna seating. It is intended for flow control in plumbing and industrial piping systems where the specified materials are compatible with the media. The 10-position lever handle allows manual adjustment across a range of throttle settings. Buyers who need flanged connections or automated actuation should select a different configuration.

Thermals noise and power draw

The valve operates without electrical power so it produces no noise and draws no current during normal use. Temperature limits are determined by the Buna seat material and the pressure rating of the ductile iron body. No cooling or external energy source is required for the lever-operated mechanism. Installers must verify that the process fluid temperature stays within the Buna seating range.

Build quality and mounting implications

The wafer pattern fits between standard flanges and is secured by the surrounding pipe bolts, so alignment depends on accurate flange spacing. The ductile iron body and aluminum bronze disc provide mechanical strength for the stated pressure class. Buna seats require compatible gaskets and lubricants to maintain sealing performance over time. The 10-position lever handle locks in set positions for repeatable flow settings.

Questions about this item

How do I install the 10" wafer butterfly valve between flanges and what step is often missed?

Center the 10" wafer body between mating flanges, insert bolts through all lug holes, and tighten in a star pattern; the step often missed is verifying the Buna seat is fully seated before torquing.

Which component of the 116-428 valve will need replacement first during routine maintenance?

The Buna liner is the primary wear item; plan to replace it when the seal shows cracking or compression set, while the aluminum bronze disc and ductile iron body typically remain serviceable.

What operational limit appears first when the T-337AB valve cycles continuously under pressure?

The 10-position lever handle's detent mechanism and Buna seat temperature rating reach their practical limits before the ductile iron body or aluminum bronze disc exhibit fatigue.
