Mute Check Valve

Type：H42X
Subtitle：Silent Anti-Water Hammer Check Valve
The Mute Check Valve is a high-performance non-return valve designed to prevent reverse flow while eliminating noise and water hammer in piping systems. Featuring a silent closure mechanism and hydraulic damping system, this valve ensures smooth, quiet operation, making it ideal for residential, commercial, and industrial applications. Constructed from ductile iron, stainless steel, or bronze, this valve is durable and corrosion-resistant, suitable for water, steam, and oil systems. Its compact design and low-pressure drop make it a reliable choice for HVAC systems, water supply networks, and fire protection systems.
