IL200 series lock-up valve, IL211 double-acting action. Signal pressure max 1.0 MPa; set pressure range 0.14 to 0.7 MPa; shut-off circuit pressure max 0.7 MPa; ambient\/fluid temperature -5 to 60 C; port size Rc1\/4 (F = G1\/4 thread); lock differential 0.01 MPa; weight 0.64 kg. Body\/pilot body\/bonnet aluminum alloy with silver baking finish; brass piston; NBR diaphragm and seals. Retains pressure at the operating area as emergency operation until air source recovers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMPN:\u003c\/strong\u003e EIL211-F02 · \u003cstrong\u003eSKU:\u003c\/strong\u003e EIL211F02\u003c\/p\u003e\u003ch2\u003eEIL211-F02 Applications\u003c\/h2\u003e\u003cp\u003eThe IL211 lock-up valve safeguards air-operated process control loops driving double-acting devices. If the air source or supply piping fails, it retains the pressure at the operating area as an emergency measure, holding the actuator position until the air supply returns to normal. Signal air acts on a diaphragm that opens the valve between IN and OUT; if signal pressure drops below the set point the valve closes by spring force. Common on control-valve positioner lines in chemical, power and process plant applications requiring fail-safe pressure retention.\u003c\/p\u003e\u003ch2\u003eEIL211-F02 Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSMC\u003c\/td\u003e\n\u003ctd\u003eManufacturer Part No.\u003c\/td\u003e\n\u003ctd\u003eEIL211-F02\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eIL200\u003c\/td\u003e\n\u003ctd\u003eAction\u003c\/td\u003e\n\u003ctd\u003eDouble acting\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSignal Pressure\u003c\/td\u003e\n\u003ctd\u003eMax. 1.0 MPa\u003c\/td\u003e\n\u003ctd\u003eSet Pressure Range\u003c\/td\u003e\n\u003ctd\u003e0.14 to 0.7 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eShut-off Circuit Pressure\u003c\/td\u003e\n\u003ctd\u003eMax. 0.7 MPa\u003c\/td\u003e\n\u003ctd\u003ePort Size\u003c\/td\u003e\n\u003ctd\u003eRc1\/4 (G1\/4)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAmbient\/Fluid Temp\u003c\/td\u003e\n\u003ctd\u003e-5 to 60 C\u003c\/td\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.64 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eAluminum alloy\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cstyle\u003e.ha-2col{display:grid;grid-template-columns:1fr 1fr;gap:44px;margin-top:34px;align-items:start}@media(max-width:768px){.ha-2col{grid-template-columns:1fr;gap:28px}}.ha-xref{display:flex;flex-wrap:wrap;gap:10px;margin:0 0 10px}.ha-xref-item{border:1px solid #e8e8e8;border-left:3px solid #e05a1e;border-radius:8px;padding:9px 16px;background:#fafafa;min-width:150px}.ha-xref-brand{display:block;font-size:11px;font-weight:800;letter-spacing:.6px;text-transform:uppercase;color:#e05a1e}.ha-xref-model{display:block;font-size:14.5px;font-weight:600;color:#1a1a1a;margin-top:2px}.ha-xref-note{font-size:12.5px;color:#777;margin:0}.ha-dl{display:inline-flex;align-items:center;gap:14px;background:#e05a1e;color:#fff!important;text-decoration:none!important;font-weight:700;font-size:15px;line-height:1.2;padding:15px 28px;border-radius:10px;box-shadow:0 3px 12px rgba(224,90,30,.28);transition:transform .16s,box-shadow .16s,background .16s}.ha-dl:hover{background:#c44d18;box-shadow:0 6px 18px rgba(224,90,30,.40);transform:translateY(-2px)}.ha-dl-ic{display:flex;align-items:center;justify-content:center;width:38px;height:38px;background:rgba(255,255,255,.18);border-radius:8px;flex-shrink:0}.ha-dl small{display:block;font-size:11.5px;font-weight:500;opacity:.92;letter-spacing:.3px;margin-top:2px}\u003c\/style\u003e\u003cdiv class=\"ha-2col\"\u003e\u003cdiv class=\"ha-col\"\u003e\n\u003ch2\u003eEIL211-F02 Datasheet \u0026amp; Manual\u003c\/h2\u003e\n\u003ca class=\"ha-dl\" href=\"https:\/\/ca01.smcworld.com\/catalog\/keiso-en\/mpv\/il200_en\/data\/il200_en.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003cspan class=\"ha-dl-ic\"\u003e\u003csvg width=\"22\" height=\"22\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#fff\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M21 15v4a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2v-4\"\u003e\u003c\/path\u003e\u003cpolyline points=\"7 10 12 15 17 10\"\u003e\u003c\/polyline\u003e\u003cline x1=\"12\" y1=\"15\" x2=\"12\" y2=\"3\"\u003e\u003c\/line\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003cspan\u003eDownload Datasheet \u0026amp; Manual\u003csmall\u003eSMC EIL211F02 · PDF · Official SMC document\u003c\/small\u003e\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":48103773274286,"sku":"EIL211F02","price":768.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/7221\/5982\/files\/02_03_2026_16_39_08_Untitled_2026_03_02T163859.297.png?v=1784196111","url":"https:\/\/hydroair.ae\/products\/eil211f02","provider":"HydroAir","version":"1.0","type":"link"}
