valve  mechanism,  and  consequently  damage  the  entire  pressure  unit.  Therefore,  during  the 
equipment operation particular attention should be paid to the following: 

-

 

Correct  setting  of  the  safety  valve,  appropriate  to  the  operating  parameters  of  the  equipment 
being protected, 

-

 

Appropriate  protection  of  the  valve  mechanism  against  unauthorized  adjustment  and  a  risk  of 
damage. The valve seal must be intact, 

-

 

Periodic inspections of the valve for correct operation according to the requirements of the office 
of technical inspection regulations. 

 

The  safety  valve  operation  inspection  involves  blowing  the  valve  by  pulling  the  handle  (wheel) 
upwards.  The  pin,  lifted  by  pulling  the  wheel  up,  releases  the  pressure  of  the  valve  spring  and 
moves the head a little up and allows the compressed air to flow through the valve.  
The handle can be loosened at the pressure equal at least 50% of the operating pressure. 
 
The  valves  delivered  require  no  special  maintenance.  They  should  only  be  periodically  (every 
1000  hours)  blown  by  pulling  the  handle  of  the  push  pin.  Special  care  must  be  taken  while 
performing this operation. Keep away from the stream of air blown out (caution 

 the air may be 

hot!). 
In  case  of  the  valve  leaks,  contact  the  manufacturer  service  to  arrange  its  repair.  The  valve 
cannot be repaired by the user itself. 
Blocking the pin, tightening the adjustment nut or covering the valve outlets is not allowed. 
In  addition  to  the  guidelines  and  requirements  listed  in  this  paragraph,  the  user  is  obliged  to 
observe the regulations being in force in the country in which the equipment is operated.  
 

 

 

 
The  safety  valves  are  intended  only  for  protection  of:  pressure  tanks,  conduits  for 
compressed  air  or  other  neutral  gases,  sources  of  compressed  air  from  overpressure 
(above the limit for that type of equipment). 
The safety valves may not be used as relief valves for pressure adjustment.
