nnnn375 DETENTED SHUTTLE VALVE
nnnnThe Lee Company's new 375 Detented
nnnnShuttle Valve is the latest addition to
nnnnLee's line of miniature detented shuttle
nnnnvalves. The poppet in this shuttle valve
nnnnlatches at either seat to close off the
nnnnemergency port or the normal port.
nnnnThis new shuttle valve is ideal for high
nnnnpressure applications with system
nnnnpressures up to 5000 psi.
nnnnThe 375 Detented Shuttle Valve is
nnnnavailable in a metal seat version, as
nnnnwell as a polymeric seat version for
nnnnapplications requiring zero leakage.
nnnnThe metal components are con-
nnnnstructed entirely of stainless steel for
nnnndurability and long life. Each detented
nnnnshuttle valve is 100% tested and in-
nnnnspected to ensure reliable, consistent
nnnnperformance.
