技术特性 [ + ]

此阀是一款先导控制,常开,电比例节流阀,带反向单向阀。比例电磁铁得电可以在先导级产生作用力,从而比例地关闭主级的阀芯。液流方向为2口流向1口。无论电比例开启还是关闭反向单向阀都允许油液从1口自由流向2口。

  • FLeX系列比例阀完美适配Sun XMD系列可扩展移动控制器。
  • 设计并通过1000万次寿命测试。
  • 疲劳和爆破等级符合NFPA测试标准T2.6.1 R2014。
  • 和其他厂家类似产品相比提高了线性度和分辨率。
  • 使用CFD流体仿真辅助设计优化几何形状。
  • 为了获得更好的性能,应当使用带颤振调节功能(100-250Hz)和电流反馈的放大器。
  • 通流能力基于200psi (14bar) 压差。
  • 根据液压回路需要,在使用FPB*以及外部补偿器进行组合的时候,需要用反向单向阀使油液能够反向自由流动。
  • 该阀的所有配置均为锌镍镀层,提供1000小时盐雾保护。
  • 多种线圈插头形式和电压可选,带或不带浪涌保护。见配置部分。
  • 不同线圈插头形式提供最高IP69K防护等级,详情见各线圈产品页面。
  • 该阀适用于740系列低功率线圈。
  • 该阀的完整参数页可以在本网页上部下载。
  • Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象

All flow is blocked, hence the term priority. The priority flow has to be satisfied.

The spring force in our flow controls equates to about 100 psi (7 bar). This is high enough to give the valves acceptable capacity (not really) and not too high for proper circuit operation. 100 psi (7 bar) is the spring force; at the upper end of the flow control's range, the drop through the valve will be as high as 250 psi (17 bar) before it starts modulating.

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

In a meter-in flow control circuit if the pump is set at 3000 psi and the load is 2000 psi the drop through the flow control is 1000 psi. In a meter-out circuit with the load at 2000 psi the drop through the flow control is 2000 psi.

We claim +/- 10%. We set to +/- 5% in production testing to allow for differences in customers' conditions. If you want accuracy, stay in the bottom 2/3rds of the range. Our 12 gpm (45 L/min.) flow controls are quite flat at 9 gpm (34 L/min.) and dead flat below 6 gpm (23 L/min.), until you get to the bottom of the range. Below about .25 gpm (1 L/min.), spool leakage and orifice conditions start to limit accuracy.

I am afraid not. Unless you are overflowing your current valve and correctly size ours, you are not likely to notice any improvement. Priority flow controls are not efficient devices. They are an easy way to get more than 1 source of oil from 1 pump but they can generate a lot of heat. Try to size your actuators so the pressures are similar on both the priority and the bypass circuits. If you can't do that, try to have the lower flow leg be the lower pressure. The pump pressure is determined by whichever leg is higher and if there is flow that is taking a pressure drop that is not doing work it is creating heat.

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.
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.
Yes. The 747 series explosion proof coils can be used on any FLeX proportional valve.
No. This cartridge only controls flow in the 2 to 1 flow direction. From 1 to 2, the valve is always fully open.

Yes. All FLeX phase 1 valves are available in the SmartConnect schematic tool, and are also available for submittal to QuickDesign.

备注 [ + ]
  • 当选择Sun阀块时,请检查插装阀的间隙要求。不同的阀控制方式以及线圈要求的间隙不一样。
  • 在阀的最大尺寸之外需增加额外的2.00 inches (50,8 mm),以进行线圈的安装和移除。
