Product Description
This solenoid-operated 3-way, 2-position cartridge is a direct-acting, poppet-style directional valve. The valve is normally open between port 1 and port 2 with port 3 blocked. Energizing the valve connects port 2 to 3 and blocks port 1. All flow paths are bidirectional and blocked paths are blocked in both directions. Due to the poppet style construction, this valve has extremely low leakage.This valve is designed to be used with 740 and 747 Series coils.The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.This valve is direct actuated and requires no minimum hydraulic pressure for operation.This cartridge has an option for manual override. See the CONFIGURATION section.
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.
Coil connector options offer ratings up to IP69K. See individual coil product pages for details.This cartridge utilizes both 740 Series high-power and 747 Series hazardous location coils.This valve is suitable for load holding applications on port 3 only. In the event of power failure, the valve would spring closed.Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles.A FULL DATA SHEET is available for this model using the link at the top of the page.
