1-1/2" NPT Y-Pattern Swing Check Valve Brass Heavy Duty Female Thread, DN40

Key features

• ONE-WAY FLOW CONTROL – This Y-Pattern Swing Check Valve prevents backflow by allowing media to flow in only one direction, helping to protect pumps and piping systems from reverse flow disruption. Angled Y-pattern structure built with enlarged inner cavity provides ample swing space for the disc, effectively reducing the risk of jamming.
• DURABLE SWING CONSTRUCTION – The swing-type disc moves freely without obstruction and ensures reliable valve closure, minimizing water hammer. Heavy-duty brass body with uniform wall thickness delivers stable pressure resistance and outstanding durability for long-term service.
• SMOOTH INTERNAL FINISH – Polished inner cavity reduces residue accumulation. Unique angled flow path lowers fluid turbulence and optimizes low pressure drop performance during operation.
• VERSATILE APPLICATION – Available in multiple sizes for residential, commercial, and industrial piping systems. Designed exclusively for horizontal installation. Suitable for water, oil, gas and air pipelines.
