SUN溢流閥RQKB-LAN產(chǎn)品介紹
強(qiáng)制降檔減壓閥的作用類(lèi)似于電氣系統(tǒng)中的斷路器。一旦入口（端口 1）處的壓力超過(guò)閥門(mén)設(shè)定值，閥門(mén)將完全打開(kāi)并保持打開(kāi)狀態(tài)，從而形成從端口 1 到油箱（端口 2）的不受限制的流動(dòng)路徑。只要端口 1 處的壓力超過(guò)端口 2 處的壓力，閥門(mén)就會(huì)保持打開(kāi)狀態(tài)。要重置閥門(mén)，從端口 1 到端口 2 的流動(dòng)必須停止，并且端口 2 處的壓力必須等于或大于端口 1 處的壓力。
? 所有2 端口泄壓閥芯（先導(dǎo)泄壓閥除外）在物理和功能上均可互換（對(duì)于給定的框架尺寸，具有相同的流路、相同的腔體）。
? 要重置閥門(mén)，必須停止流經(jīng)濾芯。
? 主級(jí)孔口由150 微米不銹鋼篩網(wǎng)保護(hù)。
? 不適合用于負(fù)載保持應(yīng)用。
? 旨在用于系統(tǒng)的執(zhí)行器側(cè)，因?yàn)榱鹘?jīng)閥門(mén)的流量必須停止，閥門(mén)才能重置。 如果在系統(tǒng)的泵側(cè)使用，則必須關(guān)閉泵流以使閥門(mén)重置。
? 油箱端口（端口2）上的背壓以1:1 的比例直接添加到閥門(mén)設(shè)置中。
? 耐腐蝕插裝閥適用于腐蝕環(huán)境，并通過(guò)型號(hào)代碼后綴/AP（外部不銹鋼部件）或/LH（外部鍍鋅鎳部件）進(jìn)行識(shí)別。
? 采用Sun 浮動(dòng)式結(jié)構(gòu)，最大限度地減少由于安裝扭矩過(guò)大和/或型腔/盒加工變化而導(dǎo)致內(nèi)部零件粘連的可能性。
Kick-down relief cartridges act similar to a circuit breaker in an electrical system. The valves will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve settting, creating an unrestricted flow path from port 1 to tank (port 2). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset the valve, flow from port 1 to port 2 must cease and pressure at port 2 must be equal to or greater than the pressure at port 1.
? All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
? To reset valve, flow through the cartridge must cease.
? Main stage orifice is protected by a 150-micron stainless steel screen.
? Not suitable for use in load holding applications.
? Intended for use on the actuator side of the system as flow through the valve must cease for the valve to reset. If used on the pump side of a system, pump flow must be shut off for the valve to reset.
? Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
? Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components.
? 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.
