SUN阀PPDBLNN产品介绍
先导式减压/泄压阀将入口（端口 2）处的高主压力降低到端口 1 处的恒定减压，并具有从端口 1 到油箱（端口 3）的全流量泄压功能。
• 从减压（端口 1）到入口（端口 2）的完全反向流动可能会导致主阀芯关闭。如果回路中需要反向自由流动，请考虑在回路中添加单独的止回阀。
• 如果先导流量消耗至关重要，请考虑使用直接作用式减压/泄压阀。
• 建议的最大入口压力由调节范围决定。范围 D、E、N 和 Q 的测试最大入口和减压之间的压差为 2000 psi (140 bar)。范围 A、B 和 H 的测试最大入口和减压之间的压差为 3000 psi (210 bar)。范围 C 和 W 的测试最大入口压力为 5000 psi (350 bar)。
• 先导式阀门具有异常平坦的压力/流量特性，非常稳定，滞后性低。
• 端口 3 处的压力以 1:1 的比例直接添加到阀门设置中，并且不应超过 5000 psi (350 bar)。
• 先导式减压阀、减压/泄压阀本质上不是快速作用阀。为了获得卓越的动态响应，请考虑直接作用阀。
• 可以指定 W 和 Y 控件（如适用），无论是否指定特殊设置。当未指定特殊设置时，可以使用 W 或 Y 控件在整个范围内调节阀门。当指定特殊设置时，此设置代表阀门的最大设置。
• 配置有 EPDM 密封件的阀芯用于磷酸酯流体系统。接触石油基流体、油脂和润滑剂会损坏密封件。
• 所有三端口减压和减压/泄压阀芯在物理上都是可互换的（即，对于给定的框架尺寸，相同的流路、相同的腔体）。考虑安装配置时，有时建议将全容量回流管线（端口 3）与减径/泄压阀筒一起使用。
• 采用 Sun 浮动式结构，以更大限度地减少由于安装扭矩过大和/或腔体/阀筒加工变化而导致内部零件卡住的可能性。
Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3).
• Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.
• If pilot flow consumption is critical, consider using direct acting reducing/relieving valves.
• Recommended maximum inlet pressure is determined by the adjustment range. Ranges D, E, N, and Q are tested with a 2000 psi (140 bar) maximum differential between inlet and reduced pressure. Ranges A, B, and H are tested with a 3000 psi (210 bar) maximum differential between inlet and reduced pressure. Ranges C and W are tested with 5000 psi (350 bar) of inlet pressure.
• Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.
• Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
• Pilot operated reducing, reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves.
• W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
• Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
• All three-port pressure reducing and reducing/relieving cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size). When considering mounting configurations, it is sometimes recommended that a full capacity return line (port 3) be used with reducing/relieving cartridges.
• 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.
