技术特性 [ + ]


  • 未获得最好性能,需要使用带有颤振信号的电流式放大器。颤振信号调节范围为100-250Hz。
  • FLeX系列比例阀完美适配Sun XMD系列可扩展移动控制器。
  • 疲劳和爆破等级符合NFPA测试标准T2.6.1 R2014。
  • 使用CFD流体仿真辅助设计优化几何形状。
  • 通流能力基于200psi (14bar) 压差。
  • 该阀的所有配置均为锌镍镀层,提供1000小时盐雾保护。
  • 该阀可以使用FLeX系列高功率或者防爆线圈。
  • 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。
  • 设计并通过一百万次以上寿命试验。
  • 直动式,无需最小工作压力。
  • 该阀在2到1口通流时具有较强的自补偿效果。1到2口通流时和外部补偿器配合使用可得到良好的比例流量控制特性。
  • 当无外部补偿器时,最大电流下1到2口通流可能会得到不同负载下的全流量。
  • 推荐维持至少50psi或者3.5bar的背压。
  • 极低的泄漏量 - 0.004 in³ (0.07 cc³)/min (1 滴/min)。
  • 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

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.

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

The valve acts as a 2 port restrictive flow control.

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.

Yes. The 747 series explosion proof coils can be used on any FLeX proportional valve.

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

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.
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。
