FLeX Series pilot-operated, normally closed, electro-proportional throttle with reverse flow check - flow 2-1
Cavity: T-162A | Capacity:
Technical specifications
This valve is a pilot-operated, normally closed, electro-proportional throttle with reverse free-flow check. Energizing the coil generates an opening force on the pilot stage which vents the main stage poppet to open proportionally, allowing flow from port 2 to 1. The check will allow flow from 1 to 2 in either the open or closed condition.
- Capacities rated at 200 psi (14 bar) differential and maximum rated coil current.
- FLeX Series proportional valves are fully compatible with the XMD Expandable Mobile Drivers from Sun.
- Designed and tested to 10 million on-off operational cycles.
- Exceeds new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
- Improved linearity and resolution over similar competing valves.
- Designed using CFD fluid simulation for optimized geometries.
- For optimum performance, an amplifier with current feedback and adjustable dither (100 - 250 Hz) should be used.
- Depending on circuit requirements, a reverse free flow check bypassing the compensator may be needed when using an FPB* with an external compensator.
- All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.
- This valve can be used with both the 740 Series high-power coils and 747 Series hazardous location coils.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details.
- A FULL DATA SHEET is available for this model using the link at the top of the page.
- 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.

- Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
- An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.
