Definition and characteristics of electric ventilation butterfly valve

1. Electric ventilation butterfly valve Usage and characteristics

　　 This butterfly valve is made of the same material as the valve body into a sealing ring, and the solenoid valve is driven by electric or pneumatic. The applicable temperature depends on the material selection of the valve body, and the nominal pressure is ≤0.6MPa. It is generally used in industrial, metallurgical, environmental protection and other pipelines for ventilation and media flow adjustment. The main features of the gas solenoid valve are: 　

　 A. Novel and reasonable design, unique structure, light weight, fast opening and closing.

　　B, small operating torque, convenient operation, labor-saving and smart.

　　C. Use suitable materials to meet the low, medium and high temperature of different media and corrosive media.

2. Electric ventilating butterfly valve adopts standard

　　Design standard: GB/T12238-2008 JB/T8692-1998 　　Flange connection size: GB/T9115.1-2000 　　Structural length h:GB/T12221-1989 　　Pressure test: GB/T13927-1992; JB/T9092-1999

Three, electric ventilation butterfly valve 　 actuator

Adopt new series GT electric actuator, high temperature solenoid valve has double-acting type and single-acting type (spring reset), gear transmission, safe and reliable; large-diameter valve adopts series AW type pneumatic actuator pull-out type transmission, reasonable structure, magnetic The column-turning liquid level gauge has a large output torque, and there are double-acting and single-acting.

　　A, gear-type double piston, large output torque, small volume.

　　B. The cylinder is made of aluminum gold, which is light in weight and beautiful in appearance.

　　C. Manual operating mechanism can be installed on the top and bottom.

　　D, rack type connection can adjust the opening angle and rated flow.

　　E, the actuator can be optional with electric signal feedback instructions and various accessories to realize automatic operation.

　　F, IS05211 standard connection provides convenience for product installation and replacement.　

　 g. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° at 0° and 90°. The electric actuator ensures the synchronization accuracy with the valve.
