Extension bar soft seal butterfly valve-WESDOM Group

Product Introduction

The design principle of an extension bar soft seal butterfly valve is based on using a circular disc or plate that rotates on an axis perpendicular to the fluid flow. The valve consists of four main components: the body, the disc, the stem, and the seat.

The body of the valve is typically constructed from cast iron, carbon steel, or stainless steel and provides the housing for the other components. The disc is a circular plate that is mounted on the stem and positioned in the center of the valve body. The stem connects the disc to the valve actuator and allows the disc to be rotated to control the flow of fluid.

The soft seal on the butterfly valve is typically made from elastomeric materials such as EPDM or Buna-N, which provide a tight seal against the flow medium. The extension bar is attached to the stem to extend the length of the valve handle, allowing the valve to be operated from a distance or in hard-to-reach locations.

The operation of an extension bar soft seal butterfly valve is based on a quarter-turn principle. When the valve actuator is rotated, the disc rotates around its axis to open or close the valve. The soft seal on the disc provides a tight shut-off against the flow medium, reducing the risk of leakage and ensuring reliable performance.
