The full-bore design keeps the internal flow path close to the nominal pipe diameter, reducing pressure drop through the valve compared with standard-port designs. A locking lever handle and adjustable packing nut add durability for long-term service.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSize note:\u003c\/strong\u003e This is the \u003cstrong\u003e1\/4-inch\u003c\/strong\u003e member of the stainless full-port ball valve series.

In a marine engine room, stainless valves are often preferred on raw water circuits and anywhere salt exposure is a factor. The 1\/4-inch size is commonly used on small-diameter instrument, gauge, and auxiliary lines. The most common selection issue is confirming the exact size needed — the series spans 1\/4 in. through 2 in., and the SKU format can be easy to misread.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564290605092,"sku":"VAL-BV1\/4S\/S","price":32.58,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/4702357d-7d78-4a71-93da-d189e62f49f7.png?v=1788727299","url":"https:\/\/marisolmarine.com\/products\/west-2158","provider":"Marisol Marine Company","version":"1.0","type":"link"}
