1. Models with an “i” suffix have a built-in position sensing switch. Model 8125 and 9010 each has a built-in switch.

2.This is the maximum pressure in MPa to which the valve can be adjusted. Some models are shipped from the factory set for lower pressures.

          1.0 MPa = 10 bar = 145 psi.

3.MBBTM (Make-Before-Break) is a patented Rheodyne design that provides uninterrupted flow when switching between LOAD and INJECT. MBB also greatly reduces transient pressure shocks.
