【 Factory direct sales of electric soft seal butterfly valve for water supply in waterworks 】 Product description

The valve stem seal is not easily deformed, thus avoiding the usual valve stem leakage phenomenon. Axial thrust bearings - prevent valve stem overload, have good centering performance - are easy to install and time-saving
It belongs to a variety of electric valves and electric regulating valves. The main connection methods are: flange type
And clamp type. It is an important execution unit in the field of industrial automation control. Belonging to electric valves
A variety of electric regulating valves.
Structure and working principle of electric butterfly valve
Usually, it is composed of an angle stroke electric actuator (0-900 partial rotation) and a butterfly valve connected mechanically, and installed and debugged together.
According to the action mode classification, there are switch type and adjustment type.
The switch type is to directly connect the power supply (AC220V or other power levels) and complete the switching action through the forward and reverse direction of the switch.
The regulating type is powered by an AC220V power supply and receives a preset parameter value of 4-20mA (0-5 weak current control) signal from the industrial automation control system to complete the regulating action.
Features of Factory Direct Sales Electric Soft Seal Butterfly Valve for Water Supply in Waterworks
1. Electric butterfly valves have the characteristics of simple structure, small size, light weight, low material consumption, small installation size, fast switching, 90 degree reciprocating rotation, and small driving torque. They are used to cut off, connect, and regulate media in pipelines, and have good fluid control characteristics and sealing performance.
2. Electric butterfly valves can transport mud with minimal liquid accumulation at the pipeline outlet. Under low pressure, good sealing can be achieved. Good regulation performance.
3. The streamlined design of the electric butterfly valve disc reduces fluid resistance loss, making it an energy-saving product.
4. The electric butterfly valve stem is a through stem structure that has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the electric 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.
5. The connection methods of electric butterfly valves include flange connection, clamp connection, butt welding connection, and lug clamp connection. The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuating mechanisms, which can achieve remote control and automated operation.
