of providing steady and precise control of
gas flow rates or pressures. The Model
EPC is a DC-driven, normally-closed valve
which includes an elastomeric valve seat
to provide bubble-tight shut-off. A broad
range of flow coefficients (Cv’s) is available
for either flow or pressure control. The
Model EPC is offered with either integral
compression fittings for in-line mounting
or as a manifoldmount version. To allow
design and user flexibility, custom
configurations in OEM-scale quantities are
