SUN閥PVJBLAN產(chǎn)品介紹
可通風(fēng)的先導(dǎo)式減壓/泄壓閥可將入口處的高一次壓力降低至端口 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。排氣口（端口 4）可用作通過先導(dǎo)閥或二通閥進(jìn)行遠(yuǎn)程控制的方法。
? 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 3000 psi (210 bar)。
? 先導(dǎo)閥在減壓和泄壓模式之間表現(xiàn)出非常低的死區(qū)過渡。
? 推薦的最大入口壓力由調(diào)節(jié)范圍決定。 D、E、N 和 Q 系列在入口壓力和減壓壓力之間的最大壓差為 2000 psi (140 bar) 的條件下進(jìn)行測試。 A、B 和 H 系列是在入口壓力和減壓壓力之間的最大壓差為 3000 psi (210 bar) 的情況下進(jìn)行測試的。 C 和 W 系列是在 5000 psi (350 bar) 入口壓力下進(jìn)行測試的。
? 先導(dǎo)閥表現(xiàn)出異常平坦的壓力/流量特性，非常穩(wěn)定且滯后性低。
? 從減壓（端口 1）到入口（端口 2）的完全反向流動(dòng)可能導(dǎo)致主閥芯關(guān)閉。如果回路中需要反向自由流動(dòng)，請考慮在回路中添加單獨(dú)的止回閥。
? 通過控制排氣口（端口 4）處的壓力，可以將閥門的有效設(shè)置控制在標(biāo)稱閥門設(shè)置以下。
? 采用 Sun 浮動(dòng)式結(jié)構(gòu)，更大限度地減少由于安裝扭矩過大和/或型腔/墨盒加工變化而導(dǎo)致內(nèi)部零件粘合的可能性。
Ventable, pilot-operated pressure reducing/relieving valves reduce a high primary pressure at the inlet to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). The vent port (port 4) can be used as a means for remote control by pilot or 2-way valves.
? Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 3000 psi (210 bar).
? Pilot operated valves exhibit very low dead-band transition between reducing and relieving modes.
? 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.
? 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.
? By controlling the pressure at the vent (port 4), the effective setting of the valve can be controlled below the nominal valve setting.
? 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.
