First, the use and characteristics of D41W ventilation butterfly valve

采用与阀体相同材料加工成密封圈,其适用温度随阀体选材而定,公称压力≤0.6MPa,一般适用于工业、冶金、环保等管道作通风调节介质流量之用。 Ventilation butterfly valve is made of the same material as the valve body into a sealing ring. The applicable temperature depends on the material selection of the valve body. The nominal pressure is ≤ 0.6 MPa. It is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation regulation of medium flow. Its main features are:
1. Novel design, reasonable, unique structure, light weight, quick opening and closing.
2. The operating torque is small, the operation is convenient, and the effort is dexterous.
3. Use adaptable materials to meet low, medium and high temperature of different media and corrosive media.

Second, D41W ventilation butterfly valve adopts standard

High Vacuum Butterfly Valve
Design standard: GB / T12238-1989 JB / T8692-1998
Flange connection size: GB / T9115.1-2000
Structure length: GB / T12221-1989
Pressure test: GB / T13927-1992; JB / T9092-1999
