Flow Regulator
SAE 8-Cartridge - 350 bar
SRP08-01
Priority style – pressure compensated
30 l/min
350 bar
The SRP08 maintains a constant outlet
flow at port 3 regardless of pressure
changes downstream on regulated port
3 or bypass port 2. The flow range is
determined by a fixed measuring orifice
and can be adjusted within a limited
range. Excess flow is diverted to the
secondary line which can be used
independently. If port 2 is closed the
valve acts as a restrictive flow regulator.
If port 3 is closed the valve will stay
closed because there is no flow/no
pressure differential over the piston.
FEATURES
z Excellent stability throughout flow range
z All surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and
ground components to ensure minimal wear and extended service life
z Rigid design using one-piece-body minimizes the effect of eccentricity
and maximizes reliability
z Low pressure drop by CFD optimized flow-path
z Optional flow ranges up to 30 l/min
z Limited flow adjustment
z Bypass flow can be pressurized for a working circuit
