The True Union Ball Valve is rated to 225 PSI at 70°F.  The "True Union" enables you to remove the valve from the system for maintenance without disturbing piping connections.  EPDM seals and seats are standard (PTFE is an option) and designed to be compatible with aggressive fluids.  The full port design ensures maximum flow at a low pressure drop. 1/2" to 6" in threaded, flange and socket connections are available.
