Check out our FAQ below or fill out our contact form for more information.

What materials are used in McKenzie Valve’s Excess Flow Check Valves?

Our Excess Flow Check Valves are constructed from high-grade stainless steel or carbon steel, providing exceptional durability and resistance to corrosion. These materials ensure reliable performance even in harsh industrial environments.

‍

Why choose McKenzie Valve’s Excess Flow Check Valves?

McKenzie Valve’s Excess Flow Check Valves are AAR-approved and built with high-quality materials, ensuring compliance with industry standards. With durable construction and reliable performance, they are specifically designed for the demanding conditions of tank car applications.

‍

How does McKenzie Valve’s Excess Flow Check Valve work?

McKenzie Valve’s Excess Flow Check Valve activates when the flow rate surpasses a set threshold, typically caused by a rupture or sudden pressure change. The valve closes automatically, stopping the flow to protect the tank car system and its contents.

‍

What is an Excess Flow Check Valve, and why is it important for tank cars?

An Excess Flow Check Valve is a safety device designed to automatically close and restrict fluid flow if the flow rate exceeds a predetermined limit. This valve is crucial for tank cars as it helps prevent leaks and spills in the event of a line break or accidental damage, ensuring the safety of operators and the environment.
