Among numerous valve products, gate and butterfly valves are commonly used valve models. However, many users do not know the difference between gate and butterfly valves when selecting, and do not know how to choose these two types of valves. In response to this issue, Liangzan Valve will introduce the differences between gate valves and butterfly valves to facilitate better selection by users.

Distinguish by definition:

Gate valve is a common type of opening and closing valve that uses a gate (i.e. the opening and closing part, in which the opening and closing part is called the gate or gate, and the gate seat is called the gate seat) to connect (fully open) or cut off (fully closed) the medium in the pipeline. It is not allowed to be used for interception, and it should be avoided to slightly open the gate during use, as the erosion of high-speed flowing media will accelerate the damage of the sealing surface. The gate plate acts as a lifting motion on a surface perpendicular to the centerline of the gate seat channel, cutting off the medium in the pipeline like a gate, hence it is called a gate valve.

Butterfly valve refers to a type of valve in which the closing element (disc or disc) is a disc that rotates around the valve axis to achieve opening and closing. It mainly serves as a shut-off and throttling valve in pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting. The butterfly valve is usually less than 90 ° from fully open to fully closed, and the butterfly valve and stem do not have self-locking ability. In order to position the butterfly plate, a worm gear reducer needs to be installed on the valve stem. The use of a worm gear reducer not only enables the butterfly plate to have self-locking ability and stop at any position, but also improves the operational performance of the valve.
