Fail-Safe Control Valve

The ARIA is designed for 1.5 million cycles and can withstand ambient temperatures up to 150°F, with travel speeds at 12 seconds per inch (nine seconds for ¾-in. stroke valves). It's equipped with an electric spring fail-safe (when opened or closed), robust enclosures with IP67/NEMA 4X enclosure, watertight ½-in. NPT fittings, and has split range input capability for 1/3-2/3 high/low applications.

 

It's designed as either Spring-Fail-Safe upon Loss-of-Power, or as Fail-In-Place on Loss-of-Power, (model dependent.) The actuator is mounted onto the control valve via pillars and mounting base and attached via a yoke locknut. The actuator stem and valve stem are connected as well.

There are 4 models to choose from in the ARIA series:

1. ARA Model: 3-Way, Flanged Steel Mix Valves; ½ to 2 in.
2. ARB Model: 2-Way & 3-Way, NPT Threaded Bronze & SS Valve; ½ to 2 in.
3. ARC Model: 2-Way & 3-Way, Flanged, Cast Iron Valves; 2-½ to 6 in.
4. ARD Model: 2-Way, Flanged Steel Cage Valves; ½ to 2 in.
