Product Introduction :

Manual butterfly valves are a type of valve that is operated by hand, typically using a lever or a handwheel to control the position of the disc within the valve body. This simple yet effective design allows for precise flow regulation in various applications, making them a popular choice in a wide range of industries. Manual butterfly valves are known for their lightweight construction and compact size which facilitate easy installation and maintenance. They provide a reliable sealing mechanism, ensuring minimal leakage when closed. The manual operation allows for immediate response to flow control needs, making them suitable for situations where automated systems are not required. Available in various materials including stainless steel, plastic and cast iron, manual butterfly valves can be customized to meet specific application requirements including pressure and temperature ratings.
