Catalog MSG14-2500/US Pressure Relief Valves
Technical Information Series R5V
General Description
Series R5V pilot operated pressure relief valves have
a similar design to the subplate mounted R4V series.
The SAE flanges allow to mount the valves directly on
s e O u t
Pha
the outlet flanges of pumps or inlet flanges of actuators
to achieve a very compact design.
Valves with SAE flanges can also be bolted together to
combine functions without the need of a manifold block.
R5V 2-Port R5V 2-Port
Operation
The system pressure in Port A is applied to the pilot
valve and to the top surface of the main poppet via an
orifice in X. The hydraulically balanced main poppet
is held against the seat by the main spring. In this
D state there is no flow 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 flow to tank. The flow through the control R5V 3-Port R5V 3-Port
orifice in X creates a pressure drop which limits the Features
pressure at the top of the main poppet to the set point.
The higher system pressure in Port A now lifts the • Pilot operated with manual adjustment
main poppet off its seat and allows flow to Port B. In • R5V with 2-port body: PHASE OUT
– 3 sizes (SAE 3/4", 1", 1-1/4")
the resulting float position only enough flow is passed
– SAE 61 flange
from Port A to Port B to maintain the inlet pressure in
Port A at the set point. When the pressure in Port A • R5V with 3-port body:
– 4 sizes (SAE 3/4", 1", 1-1/4", 1-1/2")
falls below the set point, the hydraulic balance on the
– SAE 61 and SAE 62 flange
main poppet is restored. The main spring then forces
the main poppet to close. • 3 pressure stages
• 3 adjustment modes: Hand knob, acorn nut with lead seal,
or key lock
• With optional vent function
