DESCRIPTION OF MODELS

The HG-2 type CONTROLAIR valves are handle
operated units consisting of one 3-way directional
side valve and a 3-way pressure graduating
portion. The directional side valve is arranged to
supply full supply pressure to two separate
delivery lines. The pressure graduating portion is
arranged to increase, decrease, or maintain
graduated air pressure to a second separate
delivery line.
In neutral position both delivery lines are
exhausted.
Handle movement either side of
neutral position actuates the graduating portion to
deliver graduated pressure to one of the delivery
lines as the handle is moved to full travel position.
The side valve is operated in only one direction of
handle travel movement from neutral position. A
movement of 10 degrees from neutral position
opens the 3-way side valve and directs supply
pressure to a delivery line. Further movement
past 10 degrees to full travel position (46
degrees) continues to actuate the side valve
delivery supply pressure to the delivery lines, and
continues to activate the pressure graduating
valve to deliver graduated pressure to a second
delivery line which increases in proportion to the
amount of handle movement from neutral. The
maximum graduated pressure obtained at full
handle travel depends on the value of the control
spring installed.
MODELS
The only model of the HG-2 type valve is the HG-
2-FX CONTROLAIR Valve.
equipped with a friction brake that will hold the
handle in any position selected in the handle
travel arc. The brake is internally adjustable.
