Well known as excellent pressure relief valves, Parker's series R4V and R4V*P2 for in-line mounting work stable across the whole pressure range and thus contribute to a smooth-running operation. Additionally they provide a wide range of options and connections for a versatile use in various applications.

Their design is similar to the subplate mounted R4V series. For single functions – where no manifold blocks are used – the valves can be directly placed in the pipework. R4V and R4V*P2 are available with 2 ports (L-body) or with 3 ports (T-body).

Series R4V*P2 has additionally a proportional unit between the mechanical pilot valve and the main stage. The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400.
