Standard lead time for in-stock items is 3–5\n  business days to most major ports; expedited air-freight can be arranged for line-down\n  emergencies. Each shipment includes a datasheet print-out and a mechanical-valve inspection\n  checklist. For MRO work, our team can cross-reference your failed SMC, Festo, Parker or\n  Airtac 1\/8\" 3-way mechanical valve to the POSU H-3-1\/8-S-22 form-fit-function equivalent,\n  so you can standardize on a single SKU across a multi-line pneumatic build.\n\u003c\/p\u003e\n\n\u003c!-- ============ Inquiry CTA ============ --\u003e\n\u003cdiv style=\"background-color:#16c8c8; padding:24px 32px; margin:32px 0; text-align:center; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n  \u003ch3 style=\"margin:0 0 12px 0; color:#ffffff; font-size:20px; line-height:28px;\"\u003e\n    Need H-3-1\/8-S-22 valves or a full pneumatic BOM?\n  \u003c\/h3\u003e\n  \u003cp style=\"margin:0 0 16px 0; color:#ffffff; font-size:15px; line-height:22px;\"\u003e\n    Send your part list to \u003cstrong\u003eMoritta@KOEED.COM\u003c\/strong\u003e and get availability + price within 24 hours.\n  \u003c\/p\u003e\n  \u003ca href=\"mailto:Moritta@KOEED.COM?subject=RFQ%20%E2%80%94%20H-3-1-8-S-22\" style=\"display:inline-block; background-color:#ffffff; color:#0056B3; padding:12px 24px; text-decoration:none; font-weight:bold; border-radius:4px; font-size:15px;\"\u003e\n    Request a Quote →\n  \u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"border:1px solid #0056B3; padding:16px 24px; margin:16px 0; text-align:left; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 8px 0; color:#111111; font-size:15px; line-height:22px;\"\u003e\n    Looking for more in the same series or brand?\n  \u003c\/p\u003e\n  \u003ca href=\"\/collections\/posu-pneumatics\" style=\"display:inline-block; color:#0056B3; padding:6px 18px; text-decoration:none; font-weight:bold; border:1px solid #0056B3; border-radius:4px; font-size:14px;\"\u003e\n    Browse POSU Pneumatics →\n  \u003c\/a\u003e\n   \n  \u003ca href=\"\/collections\/pneumatic-components\" style=\"display:inline-block; color:#0056B3; padding:6px 18px; text-decoration:none; font-weight:bold; border:1px solid #0056B3; border-radius:4px; font-size:14px;\"\u003e\n    Browse all Pneumatic Components →\n  \u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"border:1px solid #eeeeee; background-color:#f4fcfc; padding:16px 24px; margin:16px 0; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 4px 0; color:#111111; font-size:15px; font-weight:bold;\"\u003e\n    \u0026gt; Not sure if H-3-1\/8-S-22 fits your panel?\n  \u003c\/p\u003e\n  \u003cp style=\"margin:0 0 8px 0; color:#333333; font-size:14px;\"\u003e\n    Email \u003cstrong\u003eMoritta@KOEED.COM\u003c\/strong\u003e with a photo of your existing valve or a sketch of the pneumatic schematic — our sourcing team will cross-reference it against SMC, Festo, Parker and Airtac equivalents.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n","brand":"POSU","offers":[{"title":"Default Title","offer_id":43837881254073,"sku":"305322386569","price":238.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0268\/8476\/7929\/files\/s-l1600_9d32e5ab-b5c5-4d09-b40b-77784c848901.jpg?v=1711997922","url":"https:\/\/koeed.com\/products\/1pcs-new-for-posu-h-3-1-8-s-22-pneumatic-mechanical-valve-h-3-1-8-s-2-22","provider":"KOEED","version":"1.0","type":"link"}
