SUN阀MWGALHN产品介绍
带先导辅助装置的通风式负载反应负载控制阀结合了两个阀门:一个止回阀和一个溢流阀。止回阀允许从方向阀(端口 2)到负载(端口 1)的自由流动,而直接作用式先导辅助溢流阀则控制从端口 1 到端口 2 的流动。端口 3 处的先导辅助装置以先导比确定的速率降低溢流阀的有效设定值。端口 2 处的背压不会影响阀门设定值,因为弹簧腔参考通风口(端口 4)。
• 设置为最大负载诱导压力的至少 1.3 倍(当设置小于 2000 psi 或 140 bar 时,为 1.5 倍)。
• H 系列的最大建议负载压力为 3080 psi (212 bar)。
• J 系列的最大建议负载压力为 3850 psi (265 bar)。
• 顺时针旋转调节装置可减少设定值并释放负载。
• 对于 H 型范围,顺时针旋转设置为 1000 psi (70 bar),对于 J 型范围,顺时针旋转设置为 2000 psi (140 bar)。
• 与纯提升阀设计相比,这些阀门能够调节更大范围的流量。更长的行程使我们能够安装单向阻尼装置,使阀门平稳开启并快速关闭。
• 该阀在功能上是一种 4 通平衡阀。它作为提升阀安装,作为滑阀调节,兼具两种阀门类型的优点。
• 所有 4 端口平衡阀、负载控制阀和先导开启止回阀芯在物理上均可互换(即,对于给定的框架尺寸,具有相同的流路、相同的腔体)。
• 耐腐蚀插装阀适用于腐蚀性环境,其型号代码后缀为 /AP(外部不锈钢组件)或 /LH(外部镀锌镍组件)。
• 太阳载荷控制和平衡筒可以直接安装到执行器外壳内加工的腔体中,以增加保护并提高电路的刚度。
• 该阀门所有端口之间均有正密封。
• 该阀门具有完全泄压能力。
• 采用 Sun 浮动式结构,最大限度地减少由于安装扭矩过大和/或腔体/墨盒加工变化而导致内部零件卡住的可能性。
Vented, load reactive load control valves with pilot assist combine two valves; a check valve and a relief valve. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Backpressure at port 2 does not affect the valve setting because the spring chamber references the vent (port 4).
• Set at least 1.3 times the maximum load induced pressure (1.5 times when the setting is less than 2000 psi or 140 bar).
• The maximum recommended load pressure for the H range is 3080 psi (212 bar).
• The maximum recommended load pressure for the J range is 3850 psi (265 bar).
• Turn adjustment clockwise to decrease setting and release load.
• Full clockwise setting is 1000 psi (70 bar) for the H range and 2000 psi (140 bar) for the J range.
• These valves are capable of modulating over a broader range of flows than the pure poppet designs. The longer stroke allows us to incorporate a uni-directional damping device that smooths the opening and lets the valve close quickly.
• This valve is functionally a 4-port counterbalance valve. It seats as a poppet valve and modulates as a spool valve, offering the best of both valve types.
• All 4-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
• 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.
• Sun load control and counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
• This valve has positive seals between all ports.
• This valve has full relief capacity.
• 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.
