1. Bill of Materials represents standard materials. Equivalent or better materials
may be substituted at the manufacturer's discretion.

2. Denotes recommended spare parts.

3. Ductile Iron bodies are epoxy painted.

4. Eye Bolt is available on larger sizes only.

Ductile Iron Application Notes:

Ductile Iron 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. For example, Ductile Iron check valves (class 300 - sizes 2" ~ 24") are rated at 640 psi WOG. By comparison, Cast Iron check valves (class 250 - sizes 2" ~ 12") are rated at 500 psi
WOG and (sizes 14" ~ 24") are only rated at 300 psi WOG. Ductile Iron ANSI Classes 150 and 300 have the same bolting pattern as Cast Iron ANSI Classes 125 and 250 respectively.

1. Dimensions and weights are for reference only. When required, request certied drawings.

2. Face to face values have a tolerance of ±0.06 in (±2.0 mm) for sizes 10" and lower and a tolerance
of ±0.12 in (±3.0 mm) for sizes 12" and larger.

3. Cracking pressure is for horizontal installations only. For vertical installations, please consult factory.

PRESSURE - TEMPERATURE RATINGS

1. The above chart displays the pressure-temperature ratings for the valve's body material per
ASME B16.42-1998. Max temperature limits have been added for seat and spring materials.
Sizes 2" through 6" are dual pressure rated for both ANSI Class 150 and 300.

Titan FCI makes every effort to ensure the information presented on our literature accurately reects exact product specications. However, as product changes occur, there may be short-term differences between actual product

specications and the information contained within our literature. Titan FCI reserves the r ight to make design and specication changes to improve our products without prior notication. When required, request cer tied drawings.
