As a component used to achieve on/off and flow control in pipeline systems, electric butterfly valves are becoming increasingly popular in practical applications due to their excellent quality and performance! Electric butterfly valves can generally be divided into the most common types of electric clamp butterfly valves and electric flange butterfly valves according to their different connection methods. There are two types of sealing materials: soft sealing (normal temperature and pressure) and hard sealing (high temperature and high pressure).

Working Principle

Electric butterfly valves use electricity as the driving force. After adjusting the connection between the electric actuator and the valve stem and adjusting the electric butterfly valve, the electric seal is used as the driving force to drive the 0-90 ° rotation movement of the hard sealed butterfly valve plate. The electric butterfly valve receives 4-20mA industrial automation control system signals to accurately control the valve opening, thereby achieving the adjustment and control of different process parameters such as flow rate, temperature, and pressure.

Installation Precautions

(1) Electric butterfly valves should be installed vertically on horizontal pipelines. If there is a need for horizontally inclined equipment in special circumstances, support should generally be added.

(2) The equipment location should have good environmental conditions, and the ambient temperature should be between -25 to +55 ℃.

(3) Try to prevent equipment from being exposed to vibration sources, otherwise necessary anti vibration reinforcement measures should be taken.

(4) When installing equipment, it is necessary to point the arrow direction on the valve body or flange towards the direction of the medium.

(5) Before installing the equipment, it is necessary to carefully remove welding slag and other debris inside the pipeline. After installing the equipment, the valve core should be at a larger opening and the pipeline and butterfly valve should be cleaned again to prevent debris from getting stuck and damaging the saving parts.

(6) Electric butterfly valves should be located in a position that is easy to maintain and repair.

(7) The straight pipe section in front of the valve should be as long as possible.

(8) Export piping should use straight pipe sections with a diameter of 3-5 times the pipeline diameter.
