Electric check valve Belonging to forced sealing type valve, the electric check valve is connected with the actuator and complete the task of adjustment through receiving 1 ~ 5V intermittent contact control signal transmitted by the system or computer. When closing the valve, the pressure must be exerted to valve clack in order to avoid leakage of the forced sealing surface. Meanwhile, this type of valve is also more tightly under the action of this medium. It has the features of reliable seal, high hardness, wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long performance life. Thus it is suitable for the thermal power plant, petrochemical industry and metallurgy industry.
