技术特性 [ + ]

This FLeX Series, solenoid-operated 2-way, 2-position cartridge is a direct-acting directional poppet valve with a soft shift feature. Available in either normally open or normally closed configurations, these valves feature a pressure-balanced design, low leakage, and allow flow or blocking in both directions.

This cartridge can be installed directly into a cavity in the end of many of Sun's pilot operated and ventable valves to provide integrated pilot control.

  • 软切换阀与标准阀可替换,但是流通能力降低。
  • 软切换特性可极大地减少阀驱动时候带来的冲击,但是不宜用在计时很关键的应用中。如果需要精确的斜坡上升或计时控制,请考虑使用Sun的电比例阀。
  • 此软切换特性将比Sun的标准电磁阀显著增加响应时间。响应时间取决于流量,压力,线圈电压,油液粘度和周围的温度。典型响应时间范围为150ms到300ms。
  • 为了获得一致的软切换特性,口1应该有正压力。
  • 设计以及测试通过1000万次开关工作循环。
  • 疲劳以及爆破压力等级符合新的NFPA测试标准T2.6.1 R2014。
  • 相近的尺寸下拥有比竞争对手更高的通流能力。
  • 使用CFD流体仿真软件进行几何形状优化设计。
  • 该类阀的所有配置均配备锌-镍镀层,能够提供1000小时盐雾保护。
  • 常闭式选项可以使用FLeX低功率,高功率或者防爆线圈。常开式选项仅可以使用FLeX高功率或者防爆线圈。
  • 线圈插头提供最高IP69K防护等级,详细信息见线圈产品页。
  • 该阀提供推式手动应急选项。
  • 该阀具有极低的泄漏量 - 0.004 in³ (0.07 cc³)/min (1 滴/min)。
  • 此阀可被直接安装进Sun先导控制和外接口控制阀中以提供电磁先导控制功能。单独的先导油路被去除,只需要加工一个插孔来整合先导控制级和主级的功能。
  • 适合负载锁紧回路。
  • 详细产品页面在该网页上部可以下载浏览。
  • 不同的线圈接头与电压选项都是可选的,也同时可选带或不带浪涌保护。
  • 利用Sun浮动结构减少由于过量安装扭矩或插孔/插装阀加工误差带来的内部零件粘结的可能性。

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

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.
