1)Disc (ball) is spherical and a soft seat is incorporated into the valve seat of the body, similar to a cock.
2)When the lever handle type is used, the fluid can be stopped or flown by turning the lever handle 90 degrees. Note that the larger the size, the larger the force is required to open and close, so the gear handle can be operated.
3)Excellent airtightness is obtained from the mechanical and physical properties of soft seat materials. However, there are restrictions on the use of high-temperature areas. Suitable for “on/off operation” using open or closed operation with common soft seat. It is not suitable for use at intermediate positions, depending on the construction or material of valve.
