It features a 1-1\/4 in NPT inlet (MNPT) and a preset relief pressure of 200 psi, with a soft-seat seal for bubble-tight operation and reliable reseating after discharge. The valve supports flow up to about 1,624 CFM at set pressure and is rated for service up to 250°F, making it suitable for air lines, tanks, and other pressurized-air applications that require rapid overpressure protection. Built to ASME standards, it employs a stainless steel spring and silicone O‑ring to maintain performance in demanding environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"CDI","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677893001518,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_71d64bfe-87dd-43e5-86be-25f1adc60e19.jpg?v=1769569064","url":"https:\/\/plgautomation.com\/products\/cdi-sw12-1-1-4-npt-200psi-safety-pressure-relief-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
