The Valco design lends itself to a
unique variety of connecting slots and
port arrangements. The rotor is held
in place by a preload assembly, which
allows rotor replacement without
removing loops and tubing and
without disengaging the valve from
the actuator or mounting bracket.
In addition, the preload assembly
ensures that the valve is always
reassembled to the factory-set tension.
