This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool pilot valve used to pilot other full-flow valves. The valve is normally open between port 1 and port 2 or port 1 and port 3 and all flow paths are bidirectional. 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.
• Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).
• This cartridge utilizes 740 Series low-power and high-power coils, and 747 Series hazardous location coils for both Normally Open and Normally Closed configurations.
• 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.
• 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.
• This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
• A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
• Coils can be mounted on the tube in either direction.
• Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
