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 either the open or closed condition.

  • Les cartouches configurées avec des joints EPDM s’utilisent dans les systèmes avec des fluides ester phosphate. L’exposition de ces joints à des fluides à base de pétrole, de graisse ou de lubrifiant détériorera les joints.
  • Designed and tested to 10-million operational cycles at full-rated pressure.
  • Exceeds 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 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 cc)/min (1 drop/min).
  • This cartridge utilizes both 740 Series low-power and 747 Series hazardous location coils.
  • This valve is available with a manual push-type override option for normally open versions only.
  • Models equipped with the P control pull-type manual override allow the operator to shift the valve into a mechanically detented position by fully pulling then twisting the override counter-clockwise. This detented position will be maintained until the operator pulls and twists the manual override clockwise and allows the valve to return to its de-energized position. This pull-type manual override assembly requires a pull force of approximately 15 lbf in. (1,7 Nm) and has a mechanical life expectancy of approximately 2,000 cycles.
  • Pour les modèles équipés du dispositif de contrôle D ou L, le mécanisme d'indexage présent dans la commande manuelle est destiné à des actionnements temporaires. Les commandes manuelles de secours D, L et T ont une espérance de vie mécanique de 7000 cycles environ.
  • 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.

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.
Only external seals are serviceable.  Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.

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.

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).
