This high-flow, single-stage power valve uses a 4.5 inHg vacuum rating to respond when engine vacuum drops under load, helping deliver additional fuel when increased power demand requires it. The assembly is designed for use with four-door carburetor metering systems and is supplied as a matched pair for convenient service or multi-carburetor installations.\u003cbr\u003eThe high-flow design supports increased fuel delivery through the power circuit while maintaining a straightforward single-stage operating profile. At cruising conditions, the valve remains closed when manifold vacuum is above its calibrated opening point. As vacuum decreases during acceleration or other high-load conditions, the valve opens to supplement the main fuel circuit. This operating behavior helps support consistent fuel metering without adding unnecessary complexity to the carburetor system.\u003cbr\u003eEach Edelbrock 13145 power valve includes a gasket to help provide a proper seal during installation. Replacing the valve and gasket together can help reduce the risk of vacuum leaks and fuel leakage caused by worn or reused sealing components. Verify carburetor compatibility, thread configuration, gasket placement, and the required vacuum rating before installation. Use appropriate installation practices and follow the carburetor manufacturer’s service recommendations for adjustment and testing. The Edelbrock 13145 VRS-4150 is a practical replacement choice for restoring power-valve function in compatible high-performance carburetor applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand and Part Number: Edelbrock 13145 VRS-4150 power valve assembly\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-Flow Design: Supports increased fuel delivery through the power circuit under load\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSingle-Stage Operation: Provides a simple, predictable enrichment response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e4.5 inHg Vacuum Rating: Opens as engine vacuum drops below the calibrated threshold\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFour-Door Configuration: Designed for compatible four-door carburetor applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGasket Included: Includes sealing gaskets to support proper installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePair Quantity: Supplied as a pair for convenient replacement or multi-carburetor service\u003c\/li\u003e\u003c\/ul\u003e","brand":"EDELBROCK","offers":[{"title":"Default Title","offer_id":48724480557278,"sku":"EDE13145","price":36.84,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7690\/8766\/files\/EDE13145.jpg?v=1787952176","url":"https:\/\/www.racingsupply.ca\/products\/edelbrock-13145-edelbrock-13145-vrs-4150-4-5-inhg-high-flow-power-valve-with-gasket-pair","provider":"Racing Supply Co.","version":"1.0","type":"link"}
