Manual Butterfly Valve - Ningjin Thriveon Valve | Key Benefits

Aug . 11, 2025 01:25

Introduction to Manual Butterfly Valves

A manual butterfly valve is a type of quarter-turn valve that regulates fluid flow by rotating a disc within the valve body. Unlike pneumatic actuator butterfly valves, which rely on compressed air or gas for operation, manual valves are hand-operated, making them ideal for applications where simplicity and cost-effectiveness are prioritized. These valves are commonly used in water supply systems, HVAC, and industrial pipelines due to their compact design, ease of installation, and durability.
