Matco Norca Check Valves

High-Quality Matco Norca Check Valves

Matco Norca check valves are designed to maintain safe and reliable flow control across a wide range of industrial and municipal applications. These valves allow fluid to move in one direction while automatically preventing reverse flow, protecting pumps, piping systems and downstream equipment from potential damage. With durable construction and dependable performance, Matco Norca has become a trusted brand for check valves used in waterworks, mechanical and utility systems across the USA.

Function and Design

The primary function of a check valve is to stop backflow without requiring an operator or external control system. A Matco Norca swing check valve operates with a simple hinged disc that swings open when forward flow occurs and closes when flow reverses. This design provides an effective and economical solution for water distribution systems, wastewater plants and other industrial pipelines.

Another commonly used option is the ductile iron wafer check valve, known for its compact body and suitability in tight spaces. Wafer-style check valves are installed between flanges and are often chosen in applications where weight and space are key considerations. Matco Norca’s wafer check valves combine strength with efficiency, making them an ideal choice for both new construction and replacement projects.

Applications in Industry

Check valves play a critical role in protecting pipelines and equipment across multiple sectors:

• Water and wastewater systems – Preventing contamination from reverse flow and maintaining consistent distribution.

• Industrial facilities – Protecting pumps, compressors and piping in high-demand environments.
  

• Municipal projects – Long-term performance in watermain infrastructure and utility systems.

• HVAC and mechanical systems – Providing dependable non-return protection in circulation lines.

Because Matco check valves are built from materials like cast iron and ductile iron, they offer both durability and resistance to wear in demanding service conditions. The combination of material strength and proven designs supports reliable performance over time.

Compliance and Standards

Matco Norca check valves are manufactured to meet key industry standards, making them suitable for regulated installations in waterworks and industrial projects. Their flanged, threaded and wafer-style configurations provide flexibility for different piping layouts and system requirements.

Choosing the Right Valve

When selecting a check valve, considerations include size, pressure rating, flow media and installation space. A swing check valve is often chosen for general water applications, while a ductile iron wafer check valve may be better suited for compact industrial piping runs. Matco Norca’s product range offers options that fit both common and specialized needs in watermain and industrial systems.
