† Pressure applied simultaneously to both operators. The piston area of the KA2
operator is approximately twice that of the KA1 operator.
†† Pressure applied to port B of KA6 operator (port A open). A minimum vacuum
of 6.1 inches Hg (KS1 return) applied to A (port B open) will also operate the valve.
The KA6 operator can also be used as a differential pressure operator with or without
return spring. The differential pressure required to shift the valve without return spring
is less than 1 psig (2" Hg). To reduce the possibility of internal contamination, it is
suggested that a filter/breather be installed in the port.
