PARKER閥TDA系列介紹
TDA 系列 2 通比例節(jié)流閥用于控制大流量油。
特點(diǎn)
? 腔體和安裝模式符合 DIN ISO 7368。
? 斷電時(shí)具有故障保存功能。
? 端口 B —> A 無泄漏。
? 允許壓差高達(dá) 350 bar。
? 流量 A —> B 可選。
功能
比例流量閥設(shè)計(jì)為三級(jí)。閥芯由帶閥座結(jié)構(gòu)的順序閥芯先導(dǎo)操作。帶有力反饋的磁性、無級(jí)可調(diào)、可調(diào)閥控制順序閥芯的位置。因此，閥芯的位置不受壓差影響。壓差可達(dá)到最大工作壓力。先導(dǎo)體積要求約為 1 l/min。操作的最小壓力為 3 bar。
先導(dǎo)壓力必須大于連接 A 中的系統(tǒng)壓力的 25%。流量調(diào)節(jié)精度為 0.5%。由于漸進(jìn)特性流線，在低流量時(shí)，該值在漸進(jìn)區(qū)內(nèi)可提高 0.25%。零行程調(diào)節(jié)時(shí)間約為 25 毫秒。閥門流動(dòng)方向?yàn)閺?B 到 A。在關(guān)閉的中性位置，閥門從 B 到 A 無泄漏。在此中性位置，先導(dǎo)閥不需要任何先導(dǎo)油。油箱連接 Y 的壓力不得高于 100 bar。
The 2-way proportional throttle valves of the TDA series are used to control large oil flows.
Features
? Cavity and mounting pattern according to DIN ISO 7368.
? Fail save function at power failure.
? Leak-free from port B —> A.
? Pressure difference up to 350 bar allowed.
? Flow A —> B optional.
Function
Proportional flow valves are designed with three stages. The valve poppet is pilot-operated by a sequence spool with seat construction. A magnetic, infinitely variable, adjustable valve with force feedback controls the position of the sequence spool. Thus the position of the poppet cannot be affected by differential pressure. The differential pressure can be up to the maximum working pressure. The Pilot volume requirement amounts to approx. 1 l/min. The minimum pressure for operation is 3 bar.
The pilot pressure must be larger than 25% of the System pressure in connection A. The adjusting accuracy of the flow is 0.5%. Due to the progressive characteristic flow line, this value is improved by 0.25% in the progressive zone at low flow rates. The adjusting time for null stroke is approx. 25 ms. The valve flow direction is from B to A. The Valve is leak-free from B to A in the closed neutral position. In this neutral position, the pilot valve does not require any pilot oil. The tank connection Y must not be pressurised higher than 100 bar.
