SUN閥PPDBLWN產(chǎn)品介紹
先導式減壓/泄壓閥將入口（端口 2）處的高主壓力降低到端口 1 處的恒定減壓，并具有從端口 1 到油箱（端口 3）的全流量泄壓功能。
? 從減壓（端口 1）到入口（端口 2）的完全反向流動可能會導致主閥芯關閉。如果回路中需要反向自由流動，請考慮在回路中添加單獨的止回閥。
? 如果先導流量消耗至關重要，請考慮使用直接作用式減壓/泄壓閥。
? 建議的最大入口壓力由調(diào)節(jié)范圍決定。范圍 D、E、N 和 Q 的測試最大入口和減壓之間的壓差為 2000 psi (140 bar)。范圍 A、B 和 H 的測試最大入口和減壓之間的壓差為 3000 psi (210 bar)。范圍 C 和 W 的測試最大入口壓力為 5000 psi (350 bar)。
? 先導式閥門具有非常平坦的壓力/流量特性，非常穩(wěn)定，滯后性低。
? 端口 3 處的壓力以 1:1 的比例直接添加到閥門設置中，并且不應超過 5000 psi (350 bar)。
? 先導式減壓閥、減壓/泄壓閥本質(zhì)上不是快速作用閥。為了獲得卓越的動態(tài)響應，請考慮直接作用閥。
? W 和 Y 控件（如適用）可以指定或不指定特殊設置。當未指定特殊設置時，可以使用 W 或 Y 控件在整個范圍內(nèi)調(diào)節(jié)閥門。當指定特殊設置時，此設置代表閥門的最大設置。
? 配置有 EPDM 密封件的閥芯用于磷酸酯流體系統(tǒng)。接觸石油基流體、油脂和潤滑劑會損壞密封件。
? 所有三端口減壓和減壓/泄壓閥芯在物理上都是可互換的（即，對于給定的框架尺寸，相同的流路、相同的腔體）?？紤]安裝配置時，有時建議將全容量回流管線（端口 3）與減量/泄壓閥筒一起使用。
? 采用 Sun 浮動式結(jié)構(gòu)，以最大限度地減少由于安裝扭矩過大和/或腔體/閥筒加工變化而導致內(nèi)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.
