Wafer Type Headless Butterfly Valve

A wafer type butterfly valve is a type of valve used to control the flow of fluids in a pipeline. It belongs to the category of quarter-turn valves, meaning it can be operated by rotating the valve disc a quarter turn to either fully open or fully close the flow passage.

 

 

 

1.Our butterfly valve Using flat stem without pin of connection, driving & reliable sealing of double direction were strengthened and allowing the disc standing freely in the middle of line, and reducing the torque of opening & closing valve and isolating completely media so that eliminate leakage & corrosion. The material of this stem is Stainless Steel 416, Optional Material: 1. Steel 45# (Chinese Standard); 2. Stainless Steel 304/316; 3. Special material according to your Inquiry.

2.Top flange meets the standard of ISO 5211 and fit fitting driving devices such as handle, gear box, motorized and pneumatic actuators etc.

 

The wafer type butterfly valve is typically used in applications where space and weight considerations are important, such as HVAC systems, water treatment plants, and industrial processes. lt offers advantages such as quick and easy operation, low pressure drop, and cost-effectiveness. However, it may not be suitable for high-pressure or high-temperature applications, as it is primarily designed for moderate conditions.
