Needle Valve – Free Reverse Flow
SAE 10-Cartridge – 350 bar
SDR10A-01
160 l/min
350 bar
The SDR10A controls flow from port 2
to port 1 and is non pressure
compensated. That means the flow rate
depends on the pressure differential
and viscosity. There is free flow from
port 1 to port 2.
FEATURES
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 extend service life
z Good stability throughout flow range
z Low leakage
z Compact design
