The streamlined design of the PP butterfly valve disc reduces fluid resistance loss, making it an energy-saving product.

The stem of PP butterfly valve is a through stem structure, which has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up or down. The packing of the valve stem is not easily damaged and the seal is reliable. Fixed with the butterfly plate cone pin, the extended end is designed to prevent the valve stem from bursting out in case of accidental breakage at the connection between the valve stem and the butterfly plate.

The connection methods for PP butterfly valves include flange connection, clamp connection, butt welding connection, and lug clamp connection.

The driving forms of PP butterfly valves include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can achieve remote control and automated operation. The disadvantages of butterfly valves are as follows:

1. The pressure and working temperature range are small.

2. Poor sealing performance.
