SUN閥CBCGLJN產(chǎn)品介紹
帶先導(dǎo)輔助裝置的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)輔助裝置以先導(dǎo)比確定的速率降低泄壓閥的有效設(shè)定值。
? 平衡閥的設(shè)定值應(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)裝置以降低設(shè)定值并釋放負(fù)載。
? 順時針旋轉(zhuǎn)設(shè)定值小于 200 psi (14 bar)。
? 端口 2 處的背壓以 1 加上先導(dǎo)比乘以背壓的比率增加到有效泄壓設(shè)定值。
? 當(dāng)閥門為標(biāo)準(zhǔn)設(shè)定時，復(fù)位超過設(shè)定壓力的 85%。低于標(biāo)準(zhǔn)設(shè)定壓力的設(shè)定可能導(dǎo)致復(fù)位百分比降低。
? Sun 平衡閥芯可以直接安裝到執(zhí)行器外殼中加工的腔體中，以增加保護(hù)并提高回路的剛度。
? 提供兩種止回閥開啟壓力。除非擔(dān)心執(zhí)行器氣蝕，否則請使用 25 psi (1.7 bar) 止回閥。
? 此閥在先導(dǎo)部分沒有正向密封，在端口 2 和端口 3 之間將以高達(dá) 3 in3/min.@1000 psi (45 ml/min.@70 bar) 的速度通過。這是主從電路和閥缸組件泄漏測試中的考慮因素。
? 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、油脂和潤滑劑會損壞密封件。
? 所有 3 端口平衡閥、負(fù)載控制閥和先導(dǎo)開啟止回閥閥芯在物理上均可互換（即，對于給定的框架尺寸，流路相同、腔體相同）。
? 耐腐蝕筒式閥適用于腐蝕性環(huán)境，其型號代碼后綴為 /AP（外部不銹鋼組件）或 /LH（外部鍍鋅鎳組件）。
? 采用 Sun 浮動式結(jié)構(gòu)，以最大限度地減少由于安裝扭矩過大和/或腔體/筒式加工變化而導(dǎo)致內(nèi)部零件卡住的可能性。
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.
? 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 less than 200 psi (14 bar).
? Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.
? 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.
? Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
? Two check valve cracking pressures are available. Use the 25 psi (1,7 bar) check unless actuator cavitation is a concern.
? This valve does not have positive seals on the pilot section and will pass up to 3 in3/min.@1000 psi (45 ml/min.@70 bar ) between port 2 and port 3. This is a consideration in master-slave circuits and in the leak testing of valve-cylinder assemblies.
? 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 3-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).
? 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.
