A Flush Bottom Outlet Valve is a drain valve that can be connected "flush" to the bottom of a tank, reactor or vessel. This avoids any dead space in the vessel nozzle where solids or particles can collect. The Fetterolf Ram-Seal and Rod Seal valve are both flush bottom drain valves with exceptional sealing to process (No leakage) and many options.

A line blind valve is a pipe line component that enables a customer to change a traditional static spectacle plate, figure of 8, or orifice plate safely, within 60 seconds.

Automatic recirculation valves are used to protect centrifugal pumps that can overheat if a minimum flow is not recirculated to the pump during low flow circumstances. They are therefore sometimes referred to as minimum flow or bypass valves. They have three main functions - mainline non-return, bypass functionality and pressure letdown.
