1. As the temperature increases, the load capacity of the spring diminishes significantly. At higher temperatures, Inconel Springs must be used.

Ductile Iron check valves offer higher pressure ratings than Cast Iron check valves. For example, Ductile Iron check valves (2" ~ 24") are rated at 250 PSI WOG. By comparison, Cast Iron check valves (2" ~ 12") are rated at 200 PSI WOG and (14" ~ 24") are only rated at 150 PSI WOG.

Features:

Shut-off is achieved via the fully automatic, spring- assisted disc that closes at zero flow velocity
Quick closure of the disc reduces water hammer by creating a positive shutoff prior to flow reversal
Head loss is minimized by providing a compact face- to-face and a virtually unobstructed flow path
Ductile iron body maintains the anti-corrosive properties of cast iron while achieving a yield strength comparable to carbon steel
Can be installed in any position: vertical (with upward flow only) or horizontal
Anti-corrosive, stainless steel trim (disc, spring, and shaft) are standard
Field replaceable soft seat (o-ring) and precision machined disc ensure a bubble-tight seal

Narrow face-to-face dimensions and lightweight design provide an economical, space-saving solution
