A manually operated soft-seated butterfly valve is a type of valve used for fluid flow control in piping systems, primarily composed of the valve body, butterfly plate, valve stem, and manual operating mechanism. Its basic working principle involves rotating the valve stem through the manual operating mechanism, which in turn drives the butterfly plate to rotate around the central axis within the valve body, thereby achieving the opening and closing of the valve.

Structural Features

Compact structure, small size, light weight: The manual soft-seated butterfly valve features a simple design, easy installation, and is suitable for various installation environments.

Flexible operation: Simply rotate 90° to open or close, effortless and dexterous.

‌Reliable sealing performance: Utilizes elastic materials for sealing, such as rubber, PTFE, etc., effectively preventing medium leakage and exhibiting excellent corrosion resistance._

Wide Application Range: Suitable for various media such as water, oil, steam, and gases, with temperatures ranging from -20°C to 150°C and pressures from 1.0 Mpa to 1.6 Mpa.

Application Fields

Manually operated soft-seated wafer butterfly valves are widely used in various industrial fields, including:

Petroleum, Chemicals, Electricity: Used for regulating flow and controlling media.

Drainage and gas pipelines: play a significant role in industries such as food, light industry, and papermaking.

Environmental, Hydropower, Heating: Used to control fluid flow and pressure, meeting various industrial requirements.
