Description of Models
The H-2 Type Controlair Valves are handle operated 3-
way pressure graduating control valves. The handle actu-
ates the pressure-graduating portion to increase, de-
crease or maintain a graduated air pressure to the deliv-
ery line.
When the handle is in the "OFF" or release position the
delivery line is connected to exhaust, except in the pre-
loaded type Controlairs. Handle movement from the
"OFF" or release position actuates the pressure graduat-
ing portion to deliver a graduated pressure according to
the value of the control spring.
Models
There are several models with similar valve functions, but
different handle operating characteristics.
H-2-X Controlair Valve -Handle is spring returned to the
off position from all positions in the handle travel. Some
special models exist. See notes on Identity schedule on
page 9.
H-2-LX Controlair Valve - Handle is spring returned to off
position from all positions except at the maximum pres-
sure setting. The handle is held in the extreme position by
a mechanical detent.
H-2-FX
Controlair Valve - Handle is equipped with a
friction brake that will hold the handle in any position se-
lected in the handle travel.
H-2-EX Controlair Valve - Handle is spring returned to
"OFF" position from all other positions in the handle travel.
The "OUTLET" pressure increases from 0 to 40% of the
control pressure in the first 60 degrees of handle travel.
The outlet pressure then increases to maximum control
pressure in the remaining 32 degrees of handle travel.
H-2-EFX Controlair Valve - Handle travel and valve func-
tions are the same as H-2-EX except it is equipped with a
friction brake that holds the handle in any position select-
ed in the handle travel.
H-2-ES Controlair Valve - Valve is similar to H-2-EX ex-
cept no handle return spring or friction brake in the handle
travel.
H-2-EFS Controlair Valve- Valve is similar to H-2-EFX
except is preloaded in "release" position and handle return
spring is only effective in the first 28° of 86 degrees of
handle travel.
