What are the main working states of electro-hydraulic butterfly valves

Electro hydraulic butterfly valves are usually composed of angular stroke electric actuators and butterfly valve bodies. The angular stroke electric actuator provides power to rotate the butterfly plate around the axis, thereby achieving the opening, closing, and adjusting functions of the valve. There are mainly two sealing forms: soft seal and hard seal: soft seal is suitable for normal temperature and low pressure fluid media, and hard seal is suitable for high temperature and high pressure fluid media.
