Butterfly valves are essential components in fluid control systems, offering efficient flow regulation across various industries. Among the different types, manual butterfly valves stand out for their simplicity, reliability, and cost-effectiveness. This article provides an in-depth analysis of manual butterfly valves, covering their functionality, technical specifications, applications, and the company behind the product, Ningjin Thriveon Valve Co., Ltd..
A manual butterfly valve is a type of quarter-turn valve operated manually using a lever or gear. Unlike pneumatic or electric actuators, manual valves rely on direct human interaction for operation. This design simplifies the structure, making them ideal for applications where automation is unnecessary or cost-prohibitive.
Key operation methods include:
Compared to pneumatic actuator butterfly valves, manual valves are lighter, easier to maintain, and less prone to mechanical failures. However, they may not suit high-frequency or remote operation scenarios.
The manual butterfly valve is designed to meet rigorous industry standards, ensuring durability and performance. Below is a detailed technical specification table:
