美國SUN插裝閥RVGDLAN說明書：

This FLeX Series solenoid-operated 2-way, 2-stage cartridge is a pilot-operated directional poppet valve. The valve is low leakage and available in either a normally open or normally closed configuration to control flow from port 2 to port 1. A reverse flow check will allow flow from 1 to 2 in either the open or closed condition.

Designed and tested to 10 million on-off operational cycles.
Meets new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
Higher flow rates than competing valves of similar size.
Designed using CFD fluid simulation for optimized geometries.
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 valve exhibits extremely low leakage - 0.004 in3 (0.07 cc3)/min (1 drop/min).
This cartridge utilizes both FLeX low-power and hazardous location coils.
This valve is available with a manual push-type override option for normally open versions only.
