Double acting lock-up valve, IL200 series. Signal pressure max. 1.0 MPa; set pressure range 0.14 to 0.7 MPa (maintain 0.1 MPa or more differential between signal and set pressure); shut-off circuit pressure max. 0.7 MPa; lock differential 0.01 MPa; port size G1\/4 (thread type F = G); ambient\/fluid temperature -5 to 60 degrees C; weight 0.64 kg. Body\/pilot body\/bonnet aluminum alloy. Retains pressure at the operating area as emergency operation until the air source is recovered.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMPN:\u003c\/strong\u003e IL211-F02 · \u003cstrong\u003eSKU:\u003c\/strong\u003e IL211F02\u003c\/p\u003e\u003ch2\u003eIL211-F02 Applications\u003c\/h2\u003e\u003cp\u003eThe IL211-F02 is a double-acting lock-up valve used in air-operated process control lines. If the air source or supply piping fails, the valve holds the last operating pressure at the actuator until supply is restored, preventing uncontrolled actuator movement. Signal pressure above the set point opens the IN-to-OUT path; if signal drops below the set pressure the valve closes and locks. Suited to fail-freeze protection of pneumatic control valves and positioner-driven actuators in G-thread (G1\/4) piping systems.\u003c\/p\u003e\u003ch2\u003eIL211-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\u003eIL211-F02\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eIL200 (IL211)\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\u003ePort size\u003c\/td\u003e\n\u003ctd\u003eG1\/4 (thread type F = G)\u003c\/td\u003e\n\u003ctd\u003eSignal pressure\u003c\/td\u003e\n\u003ctd\u003eMax. 1.0 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSet pressure range\u003c\/td\u003e\n\u003ctd\u003e0.14 to 0.7 MPa\u003c\/td\u003e\n\u003ctd\u003eShut-off circuit pressure\u003c\/td\u003e\n\u003ctd\u003eMax. 0.7 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eLock differential\u003c\/td\u003e\n\u003ctd\u003e0.01 MPa\u003c\/td\u003e\n\u003ctd\u003eAmbient and fluid temperature\u003c\/td\u003e\n\u003ctd\u003e-5 to 60 C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.64 kg\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\u003eIL211-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 IL211F02 · 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":48103778189486,"sku":"IL211F02","price":867.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/7221\/5982\/files\/23_03_2026_14_46_08_IL211_F02.png?v=1784196162","url":"https:\/\/hydroair.ae\/products\/il211f02","provider":"HydroAir","version":"1.0","type":"link"}
