21A and 21L are direct acting solenoid valves. The fixed
core and armature tube are welded together to enhance
pressure resistance and leak-tightness. Valves do not require
a minimum operating pressure. A large selection
of seal materials provides wide chemical compatibility.
AC/DC interchangeability of the coil is possible for both NC
and NO configurations.
