Introduction to D941 Electric Ventilation Butterfly Valve

1、 Performance Specification for D941 Electric Ventilation Butterfly Valve

Purpose and Features

Flange ventilation butterfly valveMade of the same material as the valve body and processed into a sealing ring, using electric or pneumatic transmission. The applicable temperature depends on the material of the valve body, and the nominal pressure is ≤ 0.6MPa. It is generally used for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines. Its main characteristics are:
1. Novel and reasonable design, unique structure, light weight, and quick opening and closing.
2. The operation is powerful, easy to operate, labor-saving and agile.
3. Adopt suitable materials to meet different medium temperatures and corrosive media such as low, medium, and high.

Adopting standards

Design standard: GB/T 12238-1989 JB/T8692-1998
Flange connection size: GB/T9115.1-2000
Structural length: GB/T 12221-1989
Pressure test: GB/T 13927-92; JB/T 9092-1999
