Introduction
The Fluke 700PRV Pressure Relief Valve Kit consists of
two adjustable pressure relief valves for the Fluke 700HTP
Hydraulic Test Pump. The two valves provide a pressure
relief setting range of 50 to 400 bar (725 to 5,800 psi).
The 700HTP pump can develop pressures up to 700 bar
(10,150 psi). Application of too much pressure can damage
some pressure instruments. The pressure relief valves in
this kit provide a way to protect pressure instruments from
accidental overpressure. When the applied pressure
reaches the relief setting of the valve, the valve opens a
channel to release hydraulic fluid pressure back into the
hydraulic fluid reservoir.
Specifications
Valve Preset Value
(±10%) Relief Setting Range
Low Range:
PRV12-2-HTP1 94 bar (1360 psi) 50 to 200 bar (725 to 2,900 psi)
High Range:
PRV12-3-HTP1 376 bar (5,450 psi) 200 to 400 bar (2,900 to 5,800 psi)

Adjustment
screw
pv02f.eps
The adjustment screw is a cylinder, and has a slot for an
adjustment tool. The adjustment screw compresses a
spring, which determines the relief (cracking) pressure
setting.
Hydraulic fluid inlet and outlet ports are machined into the
body of the 700HTP pump, and are designed for this valve.
When the pressure relief valve is not in use, a threaded
plug must be installed in the pump’s pressure relief valve
port.
Selecting Which Valve to Use
The following table lists the suggested pressure relief valve
for the Fluke Pressure Modules in the 35 bar (500 psi) and
higher ranges.

Install the nylon seal in the 700HTP pressure relief valve
port first, followed by the O-ring and pressure relief valve.
Note
Use only the nylon seal provided, never thread
sealing tape, with parallel threads.
Adjusting the Pressure Relief Setting
Set the pressure relief by trial and error. The table under
Specifications shows the preset pressure relief settings at
time of shipment. To set the pressure relief lower, turn the
adjustment screw counter-clockwise (loosen it). To set
the pressure relief higher, turn the adjustment screw
clockwise (tighten it).
