Three-Way Flanged Cast Iron Globe Valve Applications
The Flowrite Two-way valves are designed for situations of water, steam, and glycol up to 50 percent. The following are extra specifications:
- Water upstream pressures as high as ANSI 125 and ANSI 250 cast iron body rating.
- Water modulating differential pressure as high as 25 psi (172 kPa) for bronze trim and 50 psi (345 kPa) for stainless steel trim.
