SKU CH-Z574-7MTYW

Semi-lug butterfly valve with ductile iron body, EPDM liner and 316 stainless steel disc rated for 200 psi water pressure and 0 to 250 degrees F

  • Handles 200 psi water pressure for demanding plumbing systems
  • Operates reliably from 0 to 250 degrees F in hot-water lines
  • Corrosion-resistant 316 stainless-steel disc extends service life
  • EPDM liner suits potable-water applications per NSF/ANSI 372
  • Lever handle gives quick manual control for maintenance shut-off

Semi-Lug Butterfly Valve 2-1/2 Inch

This semi-lug butterfly valve uses ductile iron for the body and 316 stainless steel for the disc. The EPDM liner handles water service across a 0 to 250 degrees Fahrenheit range. It fits 2-1/2 inch piping and carries a 200 psi pressure rating for commercial and residential plumbing systems.

Lever Handle Operation Standards Compliance

The lever handle provides manual flow control without external power. The valve meets standards 13D, 13R, CRN, CSA, FM, IAPMO, ICC, NFPA 13, NSF/ANSI 372, PHCC and UL Listed. Four bolt holes on a 5/8 inch bolt circle diameter secure the valve between flanges in typical installations.

Fire Protection And Potable Water Use

The certifications support use in fire sprinkler systems and potable water lines where lead-free compliance is required. Buyers who need automated actuation or larger pipe diameters will need a different valve configuration. The ductile iron body and stainless disc resist corrosion in treated water applications.

Questions about this item

How do I install the Viega 22074 ProPress butterfly valve and what step is often missed?

Press the valve onto 2-1/2" tubing using a ProPress tool with the correct jaw size; the step often missed is verifying the EPDM seal seats fully before pressing.

What maintenance or replacement will the Viega 22074 valve need over time?

Inspect the EPDM liner and 316 stainless steel disc periodically; replace the liner if it hardens or cracks after repeated thermal cycles up to 250°F.

What limit appears first when the Viega 22074 valve runs continuously at high pressure?

The 200 psi pressure rating is the first limit; sustained operation above it risks ductile iron body deformation or seal extrusion.
