Product Description
Product Description
Manual Butterfly Valve
Product introduction:
A manual butterfly valve is a type of valve that uses the rotation of a circular butterfly plate to control the on/off state or regulate the flow of fluids (such as water, air, oil, etc.) in a pipeline. It has a simple structure, small size, and convenient operation. It is usually driven by a handle or gearbox and features rapid opening and closing, low flow resistance, good sealing performance, and simple maintenance. It is widely used in pipeline systems in building, urban pipe networks, and industrial fields.
Product characteristic:
Manual butterfly valves are characterized by their compact structure, lightweight design, and quick operation. They can be opened and closed with a 90-degree rotation, offering excellent flow regulation, low flow resistance, ease of installation and maintenance, and the availability of various materials to suit different media (such as water, gas, and chemicals), while maintaining a good seal. Their streamlined valve plate design and wipeable seat make them suitable for a wide range of operating conditions, from normal temperature and pressure to high temperatures, and they are particularly suitable for large-diameter pipelines.
Product Advantages:
The advantages of manual butterfly valves are their compact structure, light weight, simple operation, convenient installation, and high cost-effectiveness. They also feature low flow resistance, rapid opening and closing (90-degree rotation), good regulation and sealing performance (especially suitable for media such as water, air, and mud), and easy maintenance with replaceable parts. They are widely used in many fields such as food, chemical, and power.
Product Applications:
Manual butterfly valves are widely used in municipal water supply and drainage, HVAC, petrochemical, power, food and beverage, pharmaceutical and environmental engineering and other fields. They are mainly used for the rapid cut-off and regulation of fluids such as gas, water, oil and steam in pipelines. They are especially suitable for large-diameter, low pressure difference and space-constrained systems. They can control and switch fluid flow through simple operation.
