SUN溢流阀RQKB-LAN产品介绍
强制降档减压阀的作用类似于电气系统中的断路器。一旦入口（端口 1）处的压力超过阀门设定值，阀门将完全打开并保持打开状态，从而形成从端口 1 到油箱（端口 2）的不受限制的流动路径。只要端口 1 处的压力超过端口 2 处的压力，阀门就会保持打开状态。要重置阀门，从端口 1 到端口 2 的流动必须停止，并且端口 2 处的压力必须等于或大于端口 1 处的压力。
• 所有2 端口泄压阀芯（先导泄压阀除外）在物理和功能上均可互换（对于给定的框架尺寸，具有相同的流路、相同的腔体）。
• 要重置阀门，必须停止流经滤芯。
• 主级孔口由150 微米不锈钢筛网保护。
• 不适合用于负载保持应用。
• 旨在用于系统的执行器侧，因为流经阀门的流量必须停止，阀门才能重置。 如果在系统的泵侧使用，则必须关闭泵流以使阀门重置。
• 油箱端口（端口2）上的背压以1:1 的比例直接添加到阀门设置中。
• 耐腐蚀插装阀适用于腐蚀环境，并通过型号代码后缀/AP（外部不锈钢部件）或/LH（外部镀锌镍部件）进行识别。
• 采用Sun 浮动式结构，最大限度地减少由于安装扭矩过大和/或型腔/盒加工变化而导致内部零件粘连的可能性。
Kick-down relief cartridges act similar to a circuit breaker in an electrical system. The valves will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve settting, creating an unrestricted flow path from port 1 to tank (port 2). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset the valve, flow from port 1 to port 2 must cease and pressure at port 2 must be equal to or greater than the pressure at port 1.
• All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
• To reset valve, flow through the cartridge must cease.
• Main stage orifice is protected by a 150-micron stainless steel screen.
• Not suitable for use in load holding applications.
• Intended for use on the actuator side of the system as flow through the valve must cease for the valve to reset. If used on the pump side of a system, pump flow must be shut off for the valve to reset.
• Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
• Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components.
• Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
