Caractéristiques techniques [ + ]

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 the closed condition. In the open condition, flow from 1 to 2 will cause the valve to auto-close and pilot flow will pass from 1 to 2.

  • 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 high-power and hazardous location coils.
  • This valve is available with a manual push-type override option for normally open versions only.
  • A FULL DATA SHEET is available for this model using the link at the top of the page.
  • Une large gamme d’options de connexions et de tensions d’alimentation des bobines est disponible, avec ou sans diode "Roue Libre" anti-self. Voir la section CONFIGURATION.
  • Cette valve intègre le concept Sun de la cartouche à visser "flottante" qui permet de minimiser les contraintes internes dues à un couple de serrage excessif de la cartouche et/ou à des écarts d’usinage des cavités ou des cartouches.

Direct acting valves are used to prevent over pressure and pilot operated valves are used to regulate pressure. If you are unsure, use a direct acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.

In many circuits the directional cartridge is set to shift at a low pressure no matter how high the pilot pressure goes. If you use a DP__ , the pilot flow increases to significant amounts. A DR__ however will only consume a small amount of flow. A DP__ is useful when you want to block or open the pilot flow to shift the valve.

Yes. All FLeX phase 1 valves are available in the SmartConnect schematic tool, and are also available for submittal to QuickDesign.
Yes. All FLeX valves utilize the Sun floating nose design.
Nominal flow capacity is based on performance limits. Maximum flow capacity is based on pressure drop. When selecting any direct-acting solenoid valve, first check the performance limits plot, then check if pressure drop is acceptable.
DF** FLeX cartridges shift at rated flow and pressure.
Notes [ + ]
  • Il est nécessaire de vérifier l'encombrement des cartouches lorsque vous sélectionnez un bloc foré. Différents types de valves, de dispositifs de contrôle, et de bobines nécessitent des encombrements disponibles différents.
  • Pour permettre l'installation ou le retrait de la bobine il est nécessaire de prévoir une hauteur libre dans le prolongement du tube magnétique d'au moins 50,8 mm (2.00 in).
