Differences Between Manual Flange Butterfly Valve and Wafer Type Manual Butterfly Valve

Connection Method

Manual flange butterfly valves connect using flanges, while wafer type manual butterfly valves connect using wafer connections. In addition, flange connections suit high-demand applications, such as high temperature and high pressure. On the other hand, wafer connections work better in situations with limited temperature and pressure.

Applicable Range

Manual flange butterfly valves typically serve applications that require high sealing and discharge capabilities. In contrast, wafer type manual butterfly valves work better for fluid control. These valves excel in situations where temperature and pressure requirements are less stringent.

Vibration Resistance

Wafer type manual butterfly valves have strong vibration resistance, making them particularly suited for environments prone to vibrations and impacts. In this regard, manual flange butterfly valves do not perform as well.

Highlights of Wafer Type Manual Butterfly Valves

Wafer type manual butterfly valves, which utilize a wafer connection, have the following characteristics:

Simple Installation

The wafer connection allows for easy installation, disassembly, and replacement. The strong clamping force prevents loosening due to pipeline vibrations and temperature changes.

Strong Vibration Resistance

Manual butterfly valves are widely used in environments with frequent vibrations, impacts, and pressure shocks, providing excellent vibration resistance.

Wide Applicability

Manual butterfly valves are suitable for controlling low-temperature and low-pressure liquid fluids, as well as low-pressure gases.

Highlights of Manual Flanged Butterfly Valves

Manual flange butterfly valves, which use flange connections, have the following benefits:

Easy Installation

Manual flange butterfly valves require only flange connections during installation. As a result, they eliminate the need for further preparatory work, saving both time and labor costs.

High Sealing Performance

These valves offer excellent sealing capabilities, making them suitable for high-demand applications.

Convenient Discharge

Manual flange butterfly valves can be equipped with reliable discharge facilities, facilitating the discharge of high-temperature and high-pressure fluids.
