RE: Gate valve
Valuable advice from a professor many years ago: First, design for graceful failure. Everything we build will eventually fail, so we must strive to avoid injuries or secondary damage when that failure occurs. Only then can practicality and economics be properly considered.
RE: Gate valve
My vote would be for a butterfly valve if you need to throttle the flow. They tend to also be a reasonable isolation valve for the size pipe you're talking about.
I consider ball valves to be best at flow isolation rather than throttling and I feel that ball valves tend to clog faster than the gate valves. Not to mention that I haven't come across a 42" ball valve.

RE: Gate valve
A gate valve used for throttling is likely to just cause endless troubles. Gate valves are good for shut-off duty but not flow control.

Yu havent mentioned if this is a pump station or in a sewage treatment facility where the fluid may be a specific type of treated sewage ie WAS, RAS etc.
