Product Overview

Butterfly valves regulate or isolate fluid flow in pipelines, making them ideal for situations requiring quick shutoff, low pressure drop, and easy operation. The butterfly valve operates with a rotating disc that allows for on/off or modulating service. Constructed from high-quality materials, including carbon steel, stainless steel, these valves are known for their durability, corrosion resistance, and suitability for various industrial applications.

Product Features

Quick Operation: Butterfly valves can be opened or closed quickly, often using a lever or actuator, allowing efficient flow control. This is particularly beneficial in industries like HVAC systems, fire protection systems, and chemical processing, where rapid flow adjustments are essential.

Low-Pressure Drop: The streamlined disc design ensures minimal resistance to flow, reducing pressure drop across the valve.

Compact and Lightweight: Butterfly valves are smaller and lighter compared to other types of valves, making them easy to install and maintain.

Versatile Connection Options: Available in wafer, lug, flanged, double flanged, and grooved connections to accommodate a wide range of piping configurations.

Resilient or Metal Seat Options: Offers both soft seats (e.g., EPDM, PTFE) for low-pressure applications and metal seats for higher temperatures and pressures.

Manual or Actuated Operation: Can be operated manually using a lever or automated with electric, pneumatic, or hydraulic actuators.
