贺尔碧格P8 385RF-NG-SPT63-B0：比例阀
这是一款先进的液压比例阀，旨在精确控制液压回路中的流体流量和压力。型号的细分为我们提供了以下线索：
P8系列：这表明它属于贺尔碧格P8系列，该系列通常为高性能直动式比例方向控制阀。
385RF-NG：这可能定义了与其尺寸、流量额定值或内部配置相关的具体特性。“RF”可能表示特定的控制类型或接口。“NG”通常指符合ISO标准的公称尺寸(NG)，该尺寸规定了歧管接口和流量。例如，NG6（CETOP 3）或NG10（CETOP 5）是常见尺寸。如果没有直接的数据表，则无法通过“NG-”确认具体的NG型号。
SPT63：此部件至关重要。“SPT”通常代表“阀芯位置传感器”。这意味着该阀门内置LVDT（线性可变差动变压器）或类似传感器，可精确测量阀芯的实际位置。这种反馈对于闭环控制至关重要，它使阀门的电子控制器能够持续比较指令位置和实际位置，并进行实时调整以实现高精度。“63”可能表示特定的传感器范围或类型。
B0：这可能是修订代码或特定的变体/选项。
贺尔比格P8比例阀的一般特点：
直动式：阀芯由比例电磁阀直接驱动，可实现快速精确的响应。
高精度：集成的阀芯位置传感器(SPT)可实现非常精确且可重复的流量和/或压力控制。这是专为闭环系统设计的比例阀的一大特点。
坚固耐用的设计：专为严苛的工业液压应用而设计，确保耐用性和长使用寿命。
电子控制：需要外部电子控制单元（通常是比例放大器卡或具有比例阀控制功能的PLC）来提供指令信号并处理传感器反馈。这允许对阀门特性进行微调。
应用：
机床：用于精确控制轴、夹紧和换刀。
塑料机械：注塑机（用于控制注射速度、压力和夹紧）。
压力机：需要精确控制力和速度的液压机。
通用工业液压：任何需要对速度、力或位置进行可变且精确控制的应用，而不仅仅是简单的开/关控制。
HOERBIGER P8 385RF-NG-SPT63-B0:Proportional Valve
This is an advanced hydraulic proportional valve designed for precise control of fluid flow and pressure in hydraulic circuits.The breakdown of the model number gives us some clues:
P8 Series:This identifies it as part of Hoerbiger’s P8 series,which are typically high-performance,direct-operated proportional directional control valves.
385RF-NG:This likely defines specific characteristics related to its size,flow rating,or internal configuration.”RF”might indicate a particular control type or interface.”NG”usually refers to the Nominal Size(NG)according to ISO standards,which specifies the manifold interface and flow capacity.For example,NG6(CETOP 3)or NG10(CETOP 5)are common sizes.Without a direct datasheet,the exact NG cannot be confirmed from”NG-“.
SPT63:This part is critical.”SPT”often stands for”Spool Position Transducer.”This means the valve incorporates a built-in LVDT(Linear Variable Differential Transformer)or similar sensor to precisely measure the actual position of the valve spool.This feedback is essential for closed-loop control,allowing the valve’s electronic controller to continuously compare the commanded position with the actual position and make real-time adjustments for high accuracy.”63″might denote a specific range or type of transducer.
B0:This is likely a revision code or a specific variant/option.
General Features of Hoerbiger P8 Proportional Valves:
Direct-Operated:The valve spool is directly actuated by a proportional solenoid,allowing for quick and precise response.
High Precision:The integrated spool position transducer(SPT)enables very accurate and repeatable control of flow and/or pressure.This is a hallmark of proportional valves designed for closed-loop systems.
Robust Design:Built for demanding industrial hydraulic applications,ensuring durability and long service life.
Electronic Control:Requires an external electronic control unit(often a proportional amplifier card or a PLC with proportional valve control capabilities)to provide the command signal and process the transducer feedback.This allows for fine-tuning of valve characteristics.
Applications:
Machine Tools:For precise control of axes,clamping,and tool changes.
Plastics Machinery:Injection molding machines(for controlling injection speed,pressure,and clamping).
Presses:Hydraulic presses requiring accurate force and speed control.
General Industrial Hydraulics:Any application where variable and precise control of speed,force,or position is required,not just simple ON/OFF control.
