Technical Information
General Description
Series R4V pilot operated, pressure relief valves for
in-line mounting have a similar design to the subplate
mounted R4V series. For single functions where no
manifold blocks are used, the valves can be directly
placed in the pipework.
The R4V valves are available with 2 ports (L-body) for
in-line relief function or with 3 ports (T-body) for relief
functions in the bypass.
Operation
The system pressure in Port A is applied to the pilot
valve and to the top surface of the main poppet via an
oriļ¬ce in X. The hydraulically balanced main poppet
is held against the seat by the main spring. In this
state there is no ļ¬ow through the valve. The adjusted
spring force acting on the pilot cone determines the
relief pressure. If the pressure in Port A exceeds the
set point, the pilot cone is lifted from its seat, releasing
a small pilot ļ¬ow to tank. The ļ¬ow through the control
oriļ¬ce in X creates a pressure drop which limits the
pressure at the top of the main poppet to the set point.
The higher system pressure in Port A now lifts the
main poppet off its seat and allows ļ¬ow to Port B. In
the resulting ļ¬oat position only enough ļ¬ow is passed
from Port A to Port B to maintain the inlet pressure in
Port A at the set point. When the pressure in Port A
falls below the set point, the hydraulic balance on the
main poppet is restored. The main spring then forces
the main poppet to close.
