SUN閥MWGALHN產(chǎn)品介紹
帶先導(dǎo)輔助裝置的通風(fēng)式負(fù)載反應(yīng)負(fù)載控制閥結(jié)合了兩個(gè)閥門：一個(gè)止回閥和一個(gè)溢流閥。止回閥允許從方向閥（端口 2）到負(fù)載（端口 1）的自由流動(dòng)，而直接作用式先導(dǎo)輔助溢流閥則控制從端口 1 到端口 2 的流動(dòng)。端口 3 處的先導(dǎo)輔助裝置以先導(dǎo)比確定的速率降低溢流閥的有效設(shè)定值。端口 2 處的背壓不會(huì)影響閥門設(shè)定值，因?yàn)閺椈汕粎⒖纪L(fēng)口（端口 4）。
? 設(shè)置為最大負(fù)載誘導(dǎo)壓力的至少 1.3 倍（當(dāng)設(shè)置小于 2000 psi 或 140 bar 時(shí)，為 1.5 倍）。
? H 系列的最大建議負(fù)載壓力為 3080 psi (212 bar)。
? J 系列的最大建議負(fù)載壓力為 3850 psi (265 bar)。
? 順時(shí)針旋轉(zhuǎn)調(diào)節(jié)裝置可減少設(shè)定值并釋放負(fù)載。
? 對(duì)于 H 型范圍，順時(shí)針旋轉(zhuǎn)設(shè)置為 1000 psi (70 bar)，對(duì)于 J 型范圍，順時(shí)針旋轉(zhuǎn)設(shè)置為 2000 psi (140 bar)。
? 與純提升閥設(shè)計(jì)相比，這些閥門能夠調(diào)節(jié)更大范圍的流量。更長(zhǎng)的行程使我們能夠安裝單向阻尼裝置，使閥門平穩(wěn)開啟并快速關(guān)閉。
? 該閥在功能上是一種 4 通平衡閥。它作為提升閥安裝，作為滑閥調(diào)節(jié)，兼具兩種閥門類型的優(yōu)點(diǎn)。
? 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(duì)于給定的框架尺寸，具有相同的流路、相同的腔體）。
? 耐腐蝕插裝閥適用于腐蝕性環(huán)境，其型號(hào)代碼后綴為 /AP（外部不銹鋼組件）或 /LH（外部鍍鋅鎳組件）。
? 太陽載荷控制和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。
? 該閥門具有完全泄壓能力。
? 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, load reactive load control valves with pilot assist combine two valves; a check valve and a relief valve. 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).
? Set at least 1.3 times the maximum load induced pressure (1.5 times when the setting is less than 2000 psi or 140 bar).
? The maximum recommended load pressure for the H range is 3080 psi (212 bar).
? The maximum recommended load pressure for the J range is 3850 psi (265 bar).
? Turn adjustment clockwise to decrease setting and release load.
? Full clockwise setting is 1000 psi (70 bar) for the H range and 2000 psi (140 bar) for the J range.
? These valves are capable of modulating over a broader range of flows than the pure poppet designs. The longer stroke allows us to incorporate a uni-directional damping device that smooths the opening and lets the valve close quickly.
? This valve is functionally a 4-port counterbalance valve. It seats as a poppet valve and modulates as a spool valve, offering the best of both valve types.
? 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).
? 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.
? Sun load control and 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.
? This valve has full relief capacity.
? 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.
