Typical<br />
<strong>Cartridge</strong><br />
Model Code<br />
■ Maximum operating pressure = 350 bar.<br />
■ Maximum valve leakage at 24 cSt = 160 cc/min. at 210 bar.<br />
■ Response time - typical = 50 ms.<br />
■ Maximum switching frequency = 15000 cycles/hr.<br />
■ Viscosity range = 10 - 600 cSt.<br />
■ This valve is direct actuated and requires no minimum hydraulic pressure for operation.<br />
■ The solenoid tube assembly is fatigue rated for 350 bar service.<br />
■ A wide variety of coil termination and voltage options are available. See Sun website: Products: Accessories: Coils.<br />
