Product Introduction

ULC butterfly valve refers to a type of butterfly valve that meets the safety and performance standards of the Underwriters Laboratories of Canada (ULC), which is a certification and testing organization accredited by the Standards Council of Canada.

A ULC butterfly valve is designed to provide reliable and safe operation. It is tested and evaluated according to ULC standards to ensure it meets the highest safety and performance requirements. These valves are commonly used in various industries and applications, including HVAC, water treatment, chemical processing, and oil and gas.

ULC butterfly valves are typically made of high-quality materials like stainless steel, carbon steel, or ductile iron. They are available in various sizes and configurations to meet different application requirements. They operate by rotating a disc inside the valve body to control the flow of fluid. The ULC certification confirms that an independent third-party organization has tested and evaluated the valve to ensure it meets the highest safety and quality standards.
