1. Ductile Iron offers higher pressure and temperature ratings than Cast Iron. Ductile Iron ANSI Classes 150 and 300 have the same bolting pattern as Cast Iron ANSI Classes 125 and 250 respectively.

Features:

Low weight and short laying length produce savings in initial cost, space requirements, and installation when compared to full-body, swing-type check valves.

Contour of body provides a short and straight flow path that generates very little turbulence. Additionally, the spring-loaded discs are designed with very low cracking pressure which reduces the amount of energy required to open the valve.

Shut-off is achieved via the fully automatic, spring-assisted discs that close near zero flow velocity. The lightweight, split disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum.

Ductile Iron body maintains the anti-corrosive properties of cast iron while achieving a yield strength comparable to carbon steel. ductile iron also offers higher pressure/temperature ratings than cast iron.

Resilient soft seats (EPDM, Viton or Buna) ensure a bubble tight seal that meets or exceeds API 598 test requirements.

Sizes 2" through 6" are designed to fit bolt circle patterns for both cast iron ANSI classes 125/300 and ductile iron ANSI classes 150/300.

Ductile Iron body maintains the anti-corrosive properties of Cast Iron while achieving a yield strength comparable to carbon steel.
