It features a body constructed from lead-free cast copper silicon alloy for durability and compliance with lead-free standards. The valve is engineered to reduce incoming high water pressure to a safer, adjustable level, protecting pipes, fixtures, and appliances from damage while also helping to reduce water consumption. It offers an adjustable pressure range from 25 to 75 psi, with a factory default setting of 50 psi, and can handle maximum inlet pressures up to 400 psi. Key components include a removable integral stainless steel strainer to protect the valve from debris, a replaceable thermoplastic seat module for easy maintenance, and a thermal expansion bypass. This bypass feature allows water to flow back toward the main supply when pressure on the outlet side increases due to thermal expansion (such as from a water heater), preventing excessive pressure buildup in the system. The valve has a sealed spring cage with stainless steel screws, making it suitable for installations in waterwork pits. It features a union inlet with NPT threads and a female NPT outlet, facilitating straightforward installation and allowing for in-line serviceability—meaning the valve can be serviced or repaired without being removed from the pipeline. This valve is part of the product line from Watts Water Technologies, a company specializing in water safety and conservation solutions.","brand":"Watts","offers":[{"title":"Default Title","offer_id":46338640642198,"sku":"QX2JXNB","price":48.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0514\/3520\/8854\/files\/rbjl5gdhhbfk3o4pcdcs.jpg?v=1776091641","url":"https:\/\/blitzstock.com\/products\/watts-lfn45b-series-1-lead-free-cast-copper-silicon-alloy-water-pressure-reducing-valve-npt-thread-union-inlet-x-npt-female-outlet-elastomer-disc-adjustable-pressure-25-to-75-psi-maximum-400-psi","provider":"Blitzstock","version":"1.0","type":"link"}
