Application

According to the structure, the electric adjustment butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type; according to the sealing form, it can be divided into soft seal type and hard seal type; soft seal type generally adopts rubber ring seal and hard seal type. Metal ring seals are usually used.For valves with a working pressure greater than 1.0 MPa and a shut-off effect on the main pipe, strength and tight performance tests shall be carried out prior to installation. Qualified and used. In the strength test, the test pressure is 1.5 times the nominal pressure, the duration is not less than 5 min, and the valve casing and packing should be free of leakage.

Feature

1. The valve seat channel has a large effective flow area and a small fluid resistance when fully opened.
2. The opening and closing torque is small. Since the butterfly plates on both sides of the rotating shaft are basically equal by the medium, the torque is generated in the opposite direction, so the opening and closing is relatively labor-saving.
3. The sealing surface material is generally made of rubber and plastic, so the low-pressure sealing performance is good.
