Product Overview

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.

Key Features

Silent Closure Mechanism: Hydraulic damping system ensures slow, controlled closure, reducing noise levels to below 50 dB(A).Eliminates water hammer and protects pumps, pipes, and fittings.

Low Resistance Design: Optimized flow path minimizes pressure drop, ensuring energy efficiency.Ideal for high-flow systems such as HVAC and water distribution networks.

Durable Construction: Body materials: Ductile iron (EN-GJS-400-18), Stainless steel (CF8M), or Bronze (C83600).Internals: Stainless steel disc and spring for corrosion resistance and long service life.

Compact & Lightweight: Space-saving design simplifies installation in tight spaces.

Compliance: Meets EN 1074, AWWA C508, and ISO 5208 standards for water and wastewater applications.
