SUN閥PPDBLNN產(chǎn)品介紹
先導(dǎo)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(dòng)可能會(huì)導(dǎo)致主閥芯關(guān)閉。如果回路中需要反向自由流動(dòng)，請(qǐng)考慮在回路中添加單獨(dú)的止回閥。
? 如果先導(dǎo)流量消耗至關(guān)重要，請(qǐng)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(cè)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(cè)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(cè)試最大入口壓力為 5000 psi (350 bar)。
? 先導(dǎo)式閥門具有異常平坦的壓力/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(shè)置中，并且不應(yīng)超過 5000 psi (350 bar)。
? 先導(dǎo)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(dòng)態(tài)響應(yīng)，請(qǐng)考慮直接作用閥。
? 可以指定 W 和 Y 控件（如適用），無論是否指定特殊設(shè)置。當(dāng)未指定特殊設(shè)置時(shí)，可以使用 W 或 Y 控件在整個(gè)范圍內(nèi)調(diào)節(jié)閥門。當(dāng)指定特殊設(shè)置時(shí)，此設(shè)置代表閥門的最大設(shè)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(rùn)滑劑會(huì)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(duì)于給定的框架尺寸，相同的流路、相同的腔體）?？紤]安裝配置時(shí)，有時(shí)建議將全容量回流管線（端口 3）與減徑/泄壓閥筒一起使用。
? 采用 Sun 浮動(dòng)式結(jié)構(gòu)，以更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(dǎo)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.
