The Oil Intensifier System (OIS) is intended to generate 
pressure up to 500 MPa (75 000 psi) using an OPG1 
(whose maximum pressure is 200 MPa (30 000 psi)).  The OIS 
includes a 5:1 intensifier.  The intensifier is used only 
when necessary to generate pressure > 200 MPa (30 000 
psi). 

n

  Position the OIS between the OPG1 and the PG7302 

with the OPG1 to the right and the PG7302 to the left. 

o

  Using a DH500 coned and threaded tube, connect 

the OPG1 lateral TEST port to the OIS's SUPPLY 
port (1). 

p

  Using a DH500 coned and threaded tube or two 

tubes and a tee, connect the PG302 TEST port to the 
OIS's lateral TEST port (2). 

 

n

  Open LOW PRESSURE SHUTOFF valve (4) and 

close INTENSIFIER SHUTOFF valve (5).  In this 
condition, OPG1 generates pressure straight through 
the Intensifier System, bypassing the intensifier. 

o

  Plug TEST port (6) if it is not being used. 

Operation:  Using Intensifier (Pressure > 200 MPa 
(30 000 psi)) 

OPG1 generates and adjusts pressure up to 200 MPa 
(30 000 psi).  Generally, the OIS intensifier is used 
only when running tests that include pressures 
greater than 200 MPa (30 000 psi).  The OIS may be 
switched into and out of use under pressure. 

n

  When running tests that include pressures above 200 

MPa (30 000 psi), connect the device under test 
(DUT) to the upper TEST connection (6) of the OIS. 

o

  Set pressures under 100 MPa (15 000 psi) using the 

OPG1 above, without the intensifier. 

p

  To switch in the intensifier, first close the LOW 

PRESSURE SHUTOFF valve (4), then open the 
INTENSIFIER SHUTOFF valve (5).  In this condition 
the OPG1 pressure is shut off from the PG7302 and 
is applied to the low side of the intensifier.  Increasing 
pressure on the low side of the intensifier results in 
pressure changes five times greater on the high side 
(PG7302 side) of the intensifier. 

q

  Use the OPG1 to generate and adjust pressure as 

necessary to set test points and float the PG7302 
piston. 

r

  Before switching out the intensifier, be sure that the 

PG7302 piston is fully down (LSTOP) as the pressure 
may change abruptly during the switching procedure.  
If possible, switch out the intensifier at the same
