Silencing Check Valve

Type：H41X
Subtitle：Silent Non-Return Valve
The Silencing Check Valve is a cost-effective non-return valve designed to prevent reverse flow and reduce water hammer in piping systems. Featuring a spring-assisted closure mechanism, this valve ensures quick sealing to minimize pressure surges, making it ideal for applications where noise reduction and budget considerations are important. Constructed from ductile iron, stainless steel, or bronze, this valve is durable and corrosion-resistant, suitable for water, steam, and oil systems. While it does not achieve zero water hammer, its spring-loaded design significantly mitigates pressure surges, offering a balance between performance and affordability.

产品概览

The Silencing Check Valve is a cost-effective non-return valve designed to prevent reverse flow and reduce water hammer in piping systems. Featuring a spring-assisted closure mechanism, this valve ensures quick sealing to minimize pressure surges, making it ideal for applications where noise reduction and budget considerations are important.

Constructed from ductile iron, stainless steel, or bronze, this valve is durable and corrosion-resistant, suitable for water, steam, and oil systems. While it does not achieve zero water hammer, its spring-loaded design significantly mitigates pressure surges, offering a balance between performance and affordability.

 

主要功能

Spring-Assisted Closure:Spring mechanism ensures rapid disc closure, reducing water hammer and noise levels.Closure speed is fixed, providing consistent performance without adjustable settings.

Cost-Effective Design:Simplified structure compared to hydraulic damping systems, offering a more affordable solution.

耐用的结构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.

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

运行优势

Water Hammer Reduction: Spring-assisted closure minimizes pressure surges, though not completely eliminated.

Cost-Effective: More affordable than hydraulic damping systems, offering excellent value for money.

Low Maintenance: Self-cleaning design and corrosion-resistant materials.

Ease of Installation: Compact and lightweight for quick integration into existing systems.
