SUN閥SCEALAN產(chǎn)品介紹
一旦入口（端口 1）處的壓力超過(guò)閥門設(shè)定值，帶有反向流動(dòng)止回閥的直接作用式順序閥將為次級(jí)回路提供流量。此外，這些閥門還包含一個(gè)整體止回閥，以提供從端口 2（順序）到端口 1（入口）的反向流動(dòng)。順序閥的壓力設(shè)定控制端口 1 處的壓力相對(duì)于排水口（端口 3）處的壓力。
? 所有 3 端口順序閥芯在物理和功能上都是可互換的（即，對(duì)于給定的框架尺寸，相同的流路、相同的腔體）。
? 雖然這是一個(gè)零先導(dǎo)流量閥，但必須連接端口 3（排水口）以保持控制腔中的壓力參考。如果端口 3 被堵塞，往復(fù)式密封泄漏將導(dǎo)致閥門發(fā)生故障。
? 端口 3 處的壓力以 1:1 的比例直接添加到閥門設(shè)定值中，并且不應(yīng)超過(guò) 5000 psi (350 bar)。
? 適用于負(fù)載保持應(yīng)用。
? 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/或腔體/墨盒加工變化而導(dǎo)致內(nèi)部零件卡住的可能性。
Direct-acting sequence valves with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
? All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
? Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction.
? Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
? Suitable for use in load holding applications.
? 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.
