SUN阀SCEALAN产品介绍
一旦入口（端口 1）处的压力超过阀门设定值，带有反向流动止回阀的直接作用式顺序阀将为次级回路提供流量。此外，这些阀门还包含一个整体止回阀，以提供从端口 2（顺序）到端口 1（入口）的反向流动。顺序阀的压力设定控制端口 1 处的压力相对于排水口（端口 3）处的压力。
• 所有 3 端口顺序阀芯在物理和功能上都是可互换的（即，对于给定的框架尺寸，相同的流路、相同的腔体）。
• 虽然这是一个零先导流量阀，但必须连接端口 3（排水口）以保持控制腔中的压力参考。如果端口 3 被堵塞，往复式密封泄漏将导致阀门发生故障。
• 端口 3 处的压力以 1:1 的比例直接添加到阀门设定值中，并且不应超过 5000 psi (350 bar)。
• 适用于负载保持应用。
• 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。
Direct-acting sequence valves with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
• All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
• Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction.
• Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
• Suitable for use in load holding applications.
• 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.
