Built with a rugged \u003cstrong\u003epowder-coated cast iron body\u003c\/strong\u003e and a \u003cstrong\u003ezinc-plated steel shaft\u003c\/strong\u003e, this manual full-port valve utilizes a \u003cstrong\u003ebeveled disc\u003c\/strong\u003e with a 75-degree rotation to manage \u003cstrong\u003elow-pressure drop\u003c\/strong\u003e performance across chilled water loops and air handling units. With a \u003cstrong\u003eCv flow coefficient\u003c\/strong\u003e of 111, it supports a flow capacity ranging from 3,489 to 13,834 SCFH, making it a staple for contractors prioritizing \u003cstrong\u003eindustrial butterfly valve\u003c\/strong\u003e reliability. The \u003cstrong\u003ecompact design\u003c\/strong\u003e includes a locking screw on the adjusting cover to secure the disk position, ensuring steady operation in tight mechanical spaces. Note that as a \u003cstrong\u003emanual butterfly valve\u003c\/strong\u003e, it is intended for throttling and flow regulation rather than tight shut-off service. This component is essential for maintaining \u003cstrong\u003eHVAC fluid regulation\u003c\/strong\u003e efficiency and high-response control within professional combustion environments.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized Flow Control:\u003c\/strong\u003e High \u003cstrong\u003eCv flow coefficient\u003c\/strong\u003e and beveled disc design minimize turbulence and \u003cstrong\u003epressure drop\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Features a \u003cstrong\u003ecast iron body\u003c\/strong\u003e and \u003cstrong\u003eBuna-N shaft packing\u003c\/strong\u003e for long-term resilience in \u003cstrong\u003eindustrial HVACR\u003c\/strong\u003e settings.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Adjustment:\u003c\/strong\u003e Includes an integrated \u003cstrong\u003eindicator plate\u003c\/strong\u003e and \u003cstrong\u003elocking screw\u003c\/strong\u003e for reliable, non-slip manual positioning.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroad Compatibility:\u003c\/strong\u003e Standard \u003cstrong\u003e1.5\" NPT connection\u003c\/strong\u003e integrates seamlessly into existing gas and air piping systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Eclipse 501218 be used as a primary shut-off valve?\u003c\/strong\u003e\u003cbr\u003e\nNo, this \u003cstrong\u003e1.5 inch butterfly valve\u003c\/strong\u003e is designed for \u003cstrong\u003eflow regulation\u003c\/strong\u003e and throttling within combustion systems; it is not rated for tight shut-off applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the maximum pressure and temperature ratings for this valve?\u003c\/strong\u003e\u003cbr\u003e\nThe manual \u003cstrong\u003eEclipse butterfly valve\u003c\/strong\u003e is rated for a \u003cstrong\u003emaximum operating pressure\u003c\/strong\u003e of 5 psig and an \u003cstrong\u003eoperating temperature range\u003c\/strong\u003e of -40°F to 140°F.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this valve compatible with automatic actuators?\u003c\/strong\u003e\u003cbr\u003e\nWhile this specific model is a \u003cstrong\u003emanual control valve\u003c\/strong\u003e, the shaft design on the \u003cstrong\u003eHoneywell Eclipse 106BV-B\u003c\/strong\u003e series often allows for field-conversion or integration with specific \u003cstrong\u003eelectric operators\u003c\/strong\u003e and mounting kits.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
