Handle Soft Sealed Wafer Butterfly Valve is a crucial fluid control equipment, widely used in industries such as oil, chemicals, power, and water treatment. It features a compact structure, easy operation, and excellent sealing performance, having become an indispensable part of modern industrial pipeline systems.

Structural Features

The handle soft-sealed wafer butterfly valve is composed of the valve body, valve plate, seal ring, handle, and connecting equipment. The valve plate features a double eccentric structure, allowing for immediate disconnection of the seal when the valve plate leaves the seat, achieving the purpose of rapid fluid cutoff. The valve plate adjusts the size and shape of the fluid passage through the handle's angle, thereby accomplishing flow regulation and fluid control.

Operating Principle

As the handle turns, the valve plate follows and the seal ring on the valve seat contacts and compresses, forming a complete seal ring. When the handle is rotated to the closed position, the valve plate moves away from the valve seat, immediately breaking the seal ring, thus cutting off the fluid passage.

Performance Features

‌Excellent sealing: Utilizes a soft sealing design with materials such as rubber, PTFE, etc., offering great elasticity and sealing performance, capable of adapting to various complex operating conditions and effectively preventing medium leakage._

Tight structure: Easy to install, space-saving, especially suitable for limited pipeline spaces.

‌Operation Simple: The handle operates simply and intuitively, allowing for easy on/off valve operation without the need for additional tools._

High Corrosion Resistance: The soft sealing materials offer excellent corrosion and wear resistance, thereby extending the lifespan of the valve.

Low flow resistance and high flow rate: The valve plate is designed with a double eccentric structure, resulting in minimal flow resistance when fully open, suitable for applications requiring high flow rates with low resistance.

Application Fields

The soft-sealed handle butterfly valve is widely used in various industries such as petrochemicals, power, and water treatment. In the petrochemical industry, it is used for transporting various oil products and chemical media, ensuring production safety; in the power industry, it is used in water treatment systems to ensure the normal operation of power equipment; in the water treatment industry, it controls water flow, ensuring the safe and stable operation of the system.
