Product Introduction

The creation of the electric soft seal butterfly valve has transformed the traditional fluid control mechanism. Electric soft-seal butterfly valves are widely used in the chemical manufacturing, oil and gas, and petroleum industries due to their unparalleled accuracy, efficiency, and sustainability. Electric soft seal butterfly valves are now the preferred choice of many organizations seeking to optimize their fluid control processes.

At its core, an electric soft seal butterfly valve is a type of quarter-turn valve that controls the flow of fluid by using a disc or vane that rotates in the pipe to either block or allow the passage of fluid. What sets the electric soft seal butterfly valve apart is its unique sealing mechanism, which employs a soft seal, usually made of materials such as EPDM, NBR, or PTFE, to ensure tight shut-off and prevent leakage.

The electric soft seal butterfly valve operates through an electric actuator that is connected to the valve’s stem. When the actuator is energized, it rotates the stem, which in turn rotates the disc or vane to control the flow of fluid. The soft seal, positioned around the circumference of the disc or vane, compresses against the seat, creating a reliable seal to prevent fluid leakage.

Advantages of electric soft seal butterfly valve!

  • High Precision

    Electric actuators provide precise and consistent control of the valve, allowing precise regulation of fluid flow.

  • Quick Operation

    The valve’s quarter-turn operation allows for fast opening and closing, reducing downtime and increasing productivity. This makes the electric soft seal butterfly valve ideal for processes that require frequent or rapid changes in fluid flow.

  • Reliable Shut-off

    The soft sealing mechanism of the electric soft seal butterfly valve ensures tight shut-off, preventing leakage and reducing the risk of environmental contamination or damage to equipment.

  • Automation Capabilities

    The electric soft seal butterfly valve can be easily integrated into automation systems, allowing for remote control and monitoring. This enables operators to adjust and optimize fluid flow parameters, enhancing process efficiency and reducing labor costs

  • Low Maintenance

    The electric soft seal butterfly valve eliminates the need for manual operation, reducing maintenance requirements and costs associated with manual valves.

  • Wide Range of Applications

    Electric soft-seal butterfly valves are widely used in the chemical manufacturing, oil and gas, and petroleum industries due to their unparalleled accuracy, efficiency, and sustainability.



Project Name: A valve dealer in Pakistan imports valves as inventory for sale.

Main Products: American standard gate valves, stainless steel check valves, ductile iron soft-sealed gate valves, wafer butterfly valves, exhaust valves and other valves.

This valve distributor from Pakistan described some informations about their company to our sales manager of the international department.They have been engaged in the valve industry for 11 years and are very professional, with a fixed customer base and sales methods. As a middleman, they need to purchase a large number of valves that are sold every day. And China is a big valve producing country, so they intend to cooperate with Chinese valve manufacturers as their own exporter. After some comparisons, the enthusiasm form WESDOM left a deep impression on them. From the initial samples, trial orders to subsequent FCL orders, the cooperation is very smooth and pleasant. This Pakistan distributor said that the cooperation with WESDOM is very pleasant, and the products and services of WESDOM are also very considerate, and will have more cooperation with WESDOM valve in the future.
