OLEOWEB阀VBCF系列参数特性

OLEOWEB阀VBCF系列描述说明及选型

Oleoweb VBCF平衡阀设计用于在可预见执行器（例如气缸或液压马达）上的重力的工作条件下获得*佳的负载控制。VBCF偏心阀是双作用的，即，它们在两个输送方向上都控制负载。它们是易折的阀门，因此可以直接应用在执行器上，从而减少滞后现象。承受重力载荷是平衡阀的基本任务之一。为了确保在负载保持方面的*佳性能，Oleoweb特别注意其液压密封平衡阀，用高强度钢制成零件，经过硬化和磨削，并在组装后仔细检查阀的尺寸和公差以及密封性。偏心阀的另一个主要任务是控制执行器的运动。由于先导比，可以在低于阀设定压力的压力下释放负载。对于Oleoweb平衡阀，可以提供不同的先导报告。对比弹簧还允许流体通道区域逐渐打开，从而即使在存在负载荷的情况下也可以控制执行器的运动，从而避免了气蚀的发生。为了获得*佳操作，建议设置平衡阀值比*大工作负荷高30％。使用塑料盖也可以密封设置，以防篡改。VBCF 平衡阀还可以执行防震阀的功能，保护连接到执行器的结构不受突然的压力峰值（例如，过高的负载或意外冲击）造成的损坏。为此，必须将分配器上的回流管连接到排水管。VBCF是一种无补偿平衡阀：回油管路上的任何残余压力都会通过提高打开阀门所需的设定压力和先导压力来抵消阀门的打开。因此，这种类型的阀更适合安装在带有开放式中心阀芯的分配器的下游，并用于在中性位置排放。Oleoweb VBCF 平衡阀是阀体中的零件：这些零件容纳在液压歧管中。该解决方案使您能够在保持整体尺寸不变的情况下管理高流量。阀体和外部部件均由高强度钢制成，并通过镀锌保护其免受腐蚀。六个表面上的车身加工确保了表面处理的*佳执行，并具有其有效性的优势。对于暴露于特别腐蚀性的腐蚀剂的应用（例如海洋应用），可应要求提供锌镍处理。钢制阀体允许在*高350 bar（5075 PSI）的工作压力下工作，并确保高耐磨性，从而提高了阀的可靠性和耐用性。VBCF阀的尺寸从BSPP 1/4“到BSPP 1/2”不等，流量高达60 lpm（15,9gpm）。

The Oleoweb VBCF counterbalance valves are designed to obtain the best control of the loads in working conditions that foresee gravitational forces on the actuators, such as cylinders or hydraulic motors. The VBCF overcenter valves are double-acting, ie they control the load in both delivery directions; they are flangable valves, which can therefore be applied directly on the actuator with consequent reduction of the hysteresis phenomenon. Sustaining a gravitational load is one of the fundamental tasks of counterbalance valves. To ensure the best performance in terms of load holding, Oleoweb takes particular care of the hydraulic seal of its counterbalance valves, making the components in high-strength steel, hardened and grinded and carefully checking dimensions and tolerances as well as the sealing of the valves once assembled. Another main task of the overcenter valves is the control of the actuator movement. Thanks to the piloting ratio, it is possible to release the load at a pressure lower than the valve setting pressure. For the Oleoweb counterbalance valves, different piloting reports are available. The contrast spring also allows a gradual opening of the fluid passage area allowing the control of the actuator movement even in the presence of negative loads and thus avoiding the onset of cavitation. For optimal operation it is advisable to set the counterbalance valve at a value 30% higher than the maximum work load. Using a plastic cap it is also possible to seal the setting, protecting it from tampering. The VBCF counterbalance valves can also perform the function of shock-proof valves, protecting the structure connected to the actuator from damage caused by sudden pressure peaks due, for example, to excessively high loads or accidental impacts. For this to be possible, the return line on the distributor must be connected to the drain. The VBCF is a non-compensated counterbalance valve: any residual pressure on the return lines counter the opening of the valve by raising the setting and pilot pressure necessary to open it. For this reason this type of valve is better suited to be installed downstream of distributors with open center spool, with uses connected to discharge in neutral position. Oleoweb VBCF counterbalance valves are parts in body valves: the components are housed inside a hydraulic manifold. This solution allows you to manage high flow rates while keeping down the overall dimensions. The valve body and external components are made of high-strength steel and are protected against corrosion by galvanizing. The processing of the body on the six faces guarantees an optimal execution of the surface treatment to the advantage of its effectiveness. For applications exposed to particularly aggressive corrosive agents (eg marine applications) the zinc-nickel treatment is available on request. The steel body allows working with operating pressures up to 350 bar (5075 PSI) and ensures a high resistance to wear to the benefit of valve reliability and durability. VBCF valves are available in sizes from BSPP 1/4 "to BSPP 1/2" for flow rates up to 60 lpm (15,9 gpm).
