Characteristics
Butterfly valves not only have simple structure, small volume, light weight, low material consumption, small installation size, small driving torque, easy operation, and fast speed, but also have good flow regulation function and closing sealing characteristics.
Advantages
-
⚙️
Butterfly valves have the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90° reciprocating rotation, and small driving torque. They are used to cut off, connect, and regulate media in pipelines, and have good fluid control characteristics.
-
💧
Butterfly valves can transport mud and accumulate the least amount of liquid at the pipeline outlet. Under low pressure, good sealing can be achieved. Good regulation performance.
-
🌊
The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving product.
-
🔩
The valve stem is a through stem structure that has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up or down. The packing of the valve stem is not easily damaged and the seal is reliable. Fixed with the butterfly plate cone pin, the extended end is designed to prevent the valve stem from bursting out in case of accidental breakage at the connection between the valve stem and the butterfly plate.
-
🔗
The connection methods include flange connection, clamp connection, butt welding connection, and lug clamp connection.
-
🤖
The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuating mechanisms, which can achieve remote control and automated operation.
Packing
📦
Standard export wooden case packaging
Application Scenarios
🏭
Widely used in pipeline systems of water supply and drainage, heating, ventilation, chemical, food and other industries, especially suitable for scenarios requiring high sealing performance and non-strongly corrosive media.
Frequently Asked Questions
❓ What is a wafer butterfly valve and how does it differ from other butterfly valve types?
A wafer butterfly valve is a type of butterfly valve designed to fit between two pipe flanges using bolts that pass through the valve body. Unlike lug-style or flanged butterfly valves, wafer butterfly valves are lightweight, compact, and cost-effective, making them ideal for tight installation spaces in standard pipeline systems.
❓ What temperature range is suitable for this wafer butterfly valve?
This wafer butterfly valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for a wide variety of industrial and commercial pipeline applications including water supply, heating, and ventilation systems.
❓ What sealing performance does this butterfly valve offer?
This butterfly valve achieves zero leakage sealing grade with bidirectional sealing direction. The concentric structure and precision investment casting workmanship ensure a reliable, tight seal under both low and standard operating pressures.
❓ What drive and actuation options are available for this valve?
This wafer butterfly valve supports multiple driving forms including manual handle/lever operation, worm gear transmission, electric actuators, pneumatic actuators, hydraulic actuators, and electro-hydraulic linkage systems. This makes it suitable for both manual local control and fully automated remote operation.
❓ In which industries can this wafer butterfly valve be applied?
This valve is widely used in pipeline systems across industries including water supply and drainage, heating, HVAC (ventilation and air conditioning), chemical processing, and food processing. It is especially suited for applications requiring high sealing performance and handling non-strongly corrosive media.
❓ What are the available connection methods for installation?
This wafer butterfly valve supports four main connection methods: flange connection, clamp connection, butt welding connection, and lug clamp connection. This flexibility allows it to be integrated into a wide range of existing pipeline configurations with ease.
