Service Information 

SM-800.6516 

The user of these devices must conform to all applicable 

electrical,  mechanical,  piping  and  other  codes  in  the 

installation, operation or repair of these devices. 
 

INSTALLATION!

  Do  not  attempt  to  install,  operate  or 

repair  these  devices  without  proper  training  in  the 

technique of working on pneumatic or hydraulic systems 

and devices, unless under trained supervision. 
Compressed  air  and  hydraulic  systems  contain  high 

levels  of  stored  energy.  Do  not  attempt  to  connect, 

disconnect  or  repair  these  products  when  a  system  is 

under  pressure.  Always  exhaust  or  drain  the  pressure 

from  a  system  before  performing  any  service  work. 

Failure to do so can result in serious personal injury. 
 

MOUNTING!

  Devices  should  be  mounted  and 

positioned  in  such  a  manner  that  they  cannot  be 

accidentally operated. 

WARNING: INSTALLATION AND 

MOUNTING 

 

DESCRIPTION OF MODELS

 

The  H-4  Type  CONTROLAIR  Valves  are  knob 

operated 3-way pressure graduating valves. The knob 

actuates  the  pressure  graduating  portion  to  increase, 

decrease  or  maintain  graduated  air  pressure  to  a 

separate delivery line. 

 

In knob “release” position the delivery line is connected 

to  exhaust.  Knob  rotation  from  release  position 

actuates  the  graduating  portion  to  deliver  graduated 

pressure  to  a  delivery  line  according  to  the  value  of 

control  spring  being  used.  The  knob  is  self  holding  in 

all positions. 

 

The  H-4  CONTROLAIR  Valve  is  available  with  either 

clockwise  rotation  or  counterclockwise  rotation  of  the 

knob increasing pressure.
