SUN閥CWGALHN產(chǎn)品介紹
帶先導(dǎo)輔助的通風(fēng)平衡閥用于控制超負(fù)荷。止回閥允許從方向閥（端口 2）到負(fù)載（端口 1）的自由流動，而直接作用式先導(dǎo)輔助泄壓閥控制從端口 1 到端口 2 的流量。端口 3 處的先導(dǎo)輔助以先導(dǎo)比確定的速率降低泄壓閥的有效設(shè)定值。端口 2 處的背壓不會影響閥門設(shè)定，因為彈簧腔參考通風(fēng)口（端口 4）。
此閥門的其他名稱包括運(yùn)動控制閥和過中心閥。
? 平衡閥的設(shè)定壓力應(yīng)至少為最大負(fù)載誘導(dǎo)壓力的1.3倍。
? 順時針旋轉(zhuǎn)調(diào)節(jié)裝置可減少設(shè)定值并釋放負(fù)載。
? 順時針旋轉(zhuǎn)設(shè)定為 200 psi (14 bar)。
? 所有 4 端口平衡閥、負(fù)載控制閥和先導(dǎo)開啟止回閥芯在物理上均可互換（即，對于給定的框架尺寸，具有相同的流路、相同的腔體）。
? 當(dāng)閥門為標(biāo)準(zhǔn)設(shè)置時，復(fù)位壓力超過設(shè)定壓力的 85%。低于標(biāo)準(zhǔn)設(shè)定壓力的設(shè)置可能會導(dǎo)致復(fù)位百分比降低。
? 端口 4 處的壓力以 1 加上先導(dǎo)比乘以壓力的比率添加到有效泄壓設(shè)定中。
? Sun 平衡筒可以直接安裝到執(zhí)行器外殼內(nèi)加工的腔體中，以增加保護(hù)并提高電路的剛度。
? 該閥門所有端口之間均有正密封。
? 與非通風(fēng)閥相比，通風(fēng)閥可能需要較低的先導(dǎo)比來實現(xiàn)機(jī)器穩(wěn)定性。
? 采用 Sun 浮動式結(jié)構(gòu)，最大限度地減少由于安裝扭矩過大和/或腔體/墨盒加工變化而導(dǎo)致內(nèi)部零件卡住的可能性。
Vented counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Backpressure at port 2 does not affect the valve setting because the spring chamber references the vent (port 4).
Other names for this valve include motion control valve and over-center valve.
? Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
? Turn adjustment clockwise to decrease setting and release load.
? Full clockwise setting is 200 psi (14 bar).
? All 4-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
? Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.
? Pressure at port 4 is added to the effective relief setting at a rate of 1 plus the pilot ratio times the pressure.
? Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
? This valve has positive seals between all ports.
? With vented valves, a lower pilot ratio may be required to achieve machine stability compared to non-vented valves.
