Air Bleed Operators
Air bleed operators have a 0.02"
(0.5 mm) diameter orifice which
connects pressure port 1 of the
main valve to the operator
piston and to atmosphere. A
small amount of air constantly
bleeds to atmosphere. The valve
spool shifts when air bleed is
stopped by a customer-supplied
on-off valve.
KA6 Low Pressure
Operator
(inline valves only)
The low pressure operator will
shift the valve spool with only 4
psig (.28 bar) applied to Port B
(Port A open). A minimum
vacuum of 6.1" Hg (with HS1
spring return) applied to port A
(Port B open) will also operated
the valve. The KA6 operator can
also be used as a differential
pressure operator with or
without spring return.the
differential pressure required to
shift the valve spool without a
spring return is less than 1 psig
(2" Hg). A filter/breather should
be installed in the open port to
reduce the possibility of internal
contamination.
KA1 Air Bias Operator
Piston area of the KA1 operator
is approximately 1/2 of the KA2
piston. When pressure is
applied to the KA1 operator the
valve spool shifts to the KA2
end. When pressure is applied
to both the KA1 and KA2
operators the valve spool shifts
to the KA1 end.
KS4 Spring Bias Operator
Piston area of the KS4 operator
is the same as the KA2
operator. The piston is the KS4
operator is spring loaded to shift
the valve spool to the KA2 end.
The valve spool shifts to the
KS4 end when pressure is
applied to the KA2 operator.
When pressure is applied to
both the KS4 and KA2
operators the valve spool shifts
to the KA2 end.
