The John Guest push-fit acetal double check valve is meticulously designed to protect against backflow or back siphonage, safeguarding against Fluid Category 3 risks.

Its low headloss design ensures superior flow characteristics, making it ideal for potable liquids, foodstuffs, intermittent hot water up to 50C, and various water treatment applications. The rapid, tool-free installation process creates a secure, leak-tight seal instantly, thanks to the unique collet locking design that holds pipes firmly in place without deformation or flow restriction. Made from durable acetal copolymer with nitrile O-rings, this valve resists corrosion and scale build-up, which extends equipment lifespan and enhances system performance.
